HELP!! I JUST LOST ALL MY FILES :”(

Ever had the roller coaster experience of trying to recover your pictures, mp3 and files after they have been infected by virus. We have been talking about backing up your files for the past two weeks. Backing up of your files isn’t limited to your computer. You can also back up files of your phone. Nowadays, with the introduction of Smart phones (the likes of blackberry, IPhones etc.), you can use your phone as a removable device (in other words a flash drive).

I am sure you all know that. Let me give examples where this feature can come in handy, you visit a friend of yours that has a particular movie  you wish to collect, all you have to do is plug in the usb cable to your phone and you collect it. That is of course, after you must have asked how big the file is. The commonest one is when you need to print a document and we don’t have a flash, we go to a café and get it printed from our phones.  It’s quite easy yes?  Though it has its disadvantages.  First of all, you can lose all files if it gets infected with virus.

Let’s talk about this for now. I have heard people say “My pictures and music are gone” or “virus has deleted my files”. As usual, let me give an example, a real life experience (this time it wasn’t me).

My friend came over to see me, he was preparing to write a job test the next day but he had to print out his pass. He didn’t have a flash on him. I asked him how he was going to print it. He said he will use his blackberry with the USB cable. I was skeptical about the whole idea; I asked him what if the system he will plug his phone to had a virus. He said he will scan it with an anti-virus, nothing spoil. I was left with no choice but to follow him.

When we got there, while my friend was busy trying to print his pass, I myself was trying to get busy as well (saw a pretty lady and started chatting her up). It was smooth sailing till my friend came around saying “My pictures and music are gone”. I started laughing, told him I will try and get it fixed when we get home”. I turned to continue the conversation, only to find out that the babe don go  L . We left the place (my friend not knowing that he had blocked P). Anyways when we got home, I had a look at the phone. It was showing 0 songs in music and 0 pictures. I decided to check the media setting to check the memory.  I found out that it was seeing the files but it wasn’t displaying them. I connected it to my system and immediately my antivirus detected and deleted virus. I decided to do a full scan on the removable device. A few more viruses were found and deleted. We thought that was going to be the end of the story. I ejected the blackberry from my system to check whether the files where back. They weren’t. I reconnected it back to the system and opened it only to discover that the files were changed to .exe format. In layman term, if I double clicked on it, I will be installing virus. This wasn’t my first time dealing with virus. I suspected that the virus had hidden the original files and created a duplicate in its place. I decided to “unhide” them. I opened my computer, I went to organize. Under the organize tab I went to folder and search option.

I navigated to the view tab

I selected it to show hidden files and I unchecked the option “hide protected operating system” and voila I could see the files. I did a victory dance. I immediately deleted the ones that were .exe and I ejected the blackberry once more. I tried checking whether the files were showing.  To my greatest disappointment, nothing. My friend was already laughing at me saying I thought you did your victory dance. He was about heading home. He said maybe some other time. I told him I must solve it today. I could remember that I have faced this problem before. I opened command prompt.

 

The blackberry was in drive j. so I did

After which I inputted this code.(make sure you don’t make a mistake).

J:\>attrib –h –r –s /s /d j:\**

This time around, it just had to work. I am pretty sure you guys saw the stress to get it back. The other option is that you don’t use it at all or if you must. Make sure you backup your files. Cheers.

S.O.S(Save Our Systems)

I am pretty sure many of you must have had thoughts about smashing your system or throwing it out of the window whenever it was painfully slow or when it hung in the middle of something important like an assignment or you are simply trying to set P. I can say for a fact that some of us have even gone as far as actually carrying out these thoughts. Hey it is ok. We are humans so it is bound to happen. Finding ways to increase the speed of your computer is the most important thing you can do as a computer user.

Before we go on, I have to tell you the truth. It is your fault that your computer is slow because you do not perform computer maintenance on it. It is your duty to speed up your computer and make it run at its optimal performance. Don’t go blaming the computer because it is slow. The reason for most slow computers has nothing to do with your CPU speed as popularly believed instead it has everything to do with junk files you keep on your computer and the lack of organization. Let us see how we can help make your computer run faster.

TIPS ON HOW TO IMPROVE THE SPEED OF YOUR COMPUTER

USE AN EXTERNAL HARD DRIVE FOR BACKUP

Nowadays there is no excuse for not backing up your files!  In our last post, we tried to see the importance of backing up your system. You can  buy a portable USB flash drive of 4GB for about N2,500 or so or a 500GB external HDD from N15000. Both these portable devices are simple to connect to the computer via a USB plug. Once connected, you will find the device if you go to your start menu and then click on computer. For systems still running XP, it will be called my computer.

Use these devices to store all of your files on, leaving your computer clean and free to work on.

UPGRADE YOUR RAM

When you buy a new computer nowadays it should come with at least 3 GB of memory installed. This should be okay for a year or two; after which you will eventually need to upgrade your memory.

People are using old computers to do new things that those computers were not made for. Upgrading your computer memory and increasing your hard drive size can help speed up an old computer.

When upgrading your computer memory in order to speed up your computer, you have two options, to do it yourself or get someone else to do it for you. If you have no clue, I would suggest you take it to a professional for the upgrade.

 

ERASE UNWANTED FILES

When I say to delete unwanted files, I do not mean you should go around your computer and start a deleting spree and remove any file you do not want. In this case, I am talking about the files that you have created yourself, and are totally aware of what they are. For example if you created a Microsoft excel document and you no longer need it, and never will, then you must ask yourself this “why still keep it’’?

This is the kind of junk that fills up your computer. Files that you have created such as documents and image files can be safely deleted by selecting  the file on your computer, right clicking on it, and choosing delete from the menu or just hitting the delete button after selecting.

AVOID DOING MANY THINGS AT THE SAME TIME

If you’re like me, you will have 10 Windows open at the same time, with your Internet browser having at least 12 tabs opened as well. Yes I know it is crazy and I’m trying to change. I have realized that some programs cannot be open at the same time as others. For example you should not be running a large program like Photoshop or Dreamweaver, while running a virus scan at the same time. We all know what the right thing to do is, but we just can’t help ourselves.

DELETE HIDDEN JUNK FILES

Hidden or temporary files are created without the user knowing. All you have to do is open files, browse the Internet (most popular), install programs, and more files are created in the background. There is so much happening in the background that most people are unaware of and do not know that this area exists. This is something you are going to have to learn about if you want to speed up your computer.

DISK CLEANUP

Disk Clean Up will get rid of the rest of the junk files that you have missed.

For systems running with windows 7, you can perform a disk clean up by going to start menu>control panel >system and security (if you cannot find it, change the ‘’view by’’ to category)> administrative tools>freedisk space.

Go to start menu>accessories>system tools>disk cleanup. You can see more information about this system tool on my computer maintenance checklist for systems running with XP.

UNINSTALL UNWANTED PROGRAMS

Are you one of those people that constantly download and install programs onto your computer? Every software program you have on your computer takes up space. It is not only taking up space, but it might also be checking for updates and connecting to the Internet. It also might be starting up when your computer starts up. There are so many good reasons why you should remove unwanted programs.

After you have removed the software program that you did not want, make sure you restart your computer to complete the process.

DEFRAG YOUR HARD DRIVE

First of all, let us talk about the meaning of fragmentation.  It occurs when storage space is used inefficiently there by reducing capacity and performance. It often leads to space being wasted as its term also means wasted space.

When you install programs and save files on your computer, the files are automatically saved to the closest available space on your hard drive. This means that files for your programs are fragmented if your hard disk drive is not organized correctly. This is why we need to de-frag our computer to place the files back together and to place the most frequently used files at the front for easy access.

You should defrag your computer at least once a week if you use your computer often. If you do not use your computer that often, then you can defrag less often.

For systems running with windows 7, you can defragment your disk drive by going to start menu>control panel >system and security (if you cannot find it, change the ‘’view by’’ to category)> administrative tools>defragment your hard drive. If you are still using xp, the Windows disk defragmenter is located at start menu>accessories>system tools>disk defragmenter, you can choose to “analyze” first before you choose defrag. This feature will tell you if you need to perform this task or not.

PAY FOR AN ANTI VIRUS PROGRAM!

Don’t get me wrong there is nothing wrong with a free anti-virus program. In fact I will recommend Avast as my number one freebie. However, even though this can secure your system, it is safer to have the extra security features that come with the paid versions. Nowadays most new antivirus also comes with a firewall that if they do not, Windows provides a perfectly good firewall for free.

If you do not have an anti virus program installed you are risking everything. Is that really worth the trouble?

UPDATE YOUR APPLICATIONS AND PROGRAMS REGULARLY

Every program on your computer must be updated regularly. If you do not do this, you will have problems, guaranteed! Even Windows itself needs updating, along with any other applications and games, and even hidden device driver software.

To see if your device drivers are performing properly you can go to the Control Panel, click on system, advanced settings, and then you will find device manager under the hardware tab.

I use a program called Driver detector. Most computers need a program like this because having outdated driver software on your computer can disastrous. Having the wrong driver software on your computer can cause black screens, blue screens, and total computer crashes.

To find out if Windows needs updating, simply go to your start menu and type in the search section, “Windows update”.

DISABLE UNNECESSARY START UP PROGRAMS

When you boot into your computer it is not only the Windows operating system that is starting, as most people have many other programs starting at the same time. To speed up this process you need to disable startup programs.

To do this, go to the run menu by holding down the windows key and pressing the ‘’R’’ key. After which type ‘’msconfig’’. Click the start up tab and deselect the programs that do not need to start up with the system, for example yahoo messenger and ITunes.

A great way to speed up your computer is not to overwork it in the first place. For example most people have five or six programs open at the same time and they really aren’t using all of them. Close down programs you are not using.

USING THE RIGHT POWER OPTION (LAPTOPS)

Although all of these tips above can speed up your laptop, this one applies to laptops only.

All laptops built in the last 5-8 years make their batteries last longer by slowing down the computer processor when you don’t seem to be using all of it. Although this works great to prolong battery life, it means that your laptop runs slower when it runs off battery.

To switch your laptop back into normal mode, all you have to do is plug in your laptop and the computer processor will run at full power, giving you 100% of the speed you expected when you bought the laptop.

I believe I have done my good deed for the day. The rest is up to you to do. Cheers

Preparing for that Disaster

I am not talking about the end of the world here, so you can relax. I am referring to the disaster that affects the IT world like when your system “crashes’’. A system will crash for either of these two reasons if not both. First of all, as a result of the Operating system becoming corrupt or the hard disk drive getting bad. Both can happen as a result of improper or forceful shut down of your system either by you or the system (when you have a bad battery). The corrupt OS can be solved either by repairing the OS or Installing a new OS (format) while for the Hard disk drive; sadly the only logical thing to do is to replace it.
I know a lot of you will be saying you can back up your files, yes you are right. You can back up, problem solved. But then again ask yourself, what happens when your back up fails or gets missing. A lot of you will be saying that’s not possible. Let me tell you a real life experience and to let you know it can happen. I have this system, the battery is bad (I have been looking to replace it, I am serious x_x). Anyways, like you know the light situation isn’t perfect, anytime the light goes, few minutes later my laptop goes off. This was happening a lot, anyhow I will just put it on whenever they brought the light; till one faithful day I put on my system and it was started up, gave it to my friend, I think he was trying to copy something from his external hard drive to my system, during the process of copying, my system froze for about 30 minutes, anyways I pressed the power button to shut it down. When I tried putting it on, a message came up that windows could not start up. I tried to do the start up repair, took 48 hours and it couldn’t be solved, PHCN decided to put me out of my misery by taking light(my battery still bad) When they brought the light, my system refused to come on. I mean it just didn’t come on. Something told me to try bending it on its side. I know it sounds crazy but I was desperate. I bent it and you would believe it came on. I took a picture so u guys will see I am not lying.

 

 

When the system came on, I had to reinstall the old OS. I didn’t mind at least it came on. I already had back up my files on my external hard disk, on a flash drive and on my friend’s system. I was extremely thorough. Anyways my system was taking a long time to reinstall the OS. I am not talking about hours here, talking about days. I am pretty sure you know what happened next, PHCN struck. I was becoming fed up with it but I had no one to blame except myself. I turned it on and had to do the same process over again and it even had to do a check disk on the hard drive. It was taking days again, I have already lost over a week’s worth of work. PHCN finally put the dagger in the heart. They struck and that was the end of the hard drive. You are asking how did I know? I was suspecting that the hard drive might be the cause so I opened the system and kept it one of those hard drive casing with USB and tried repairing it from another system. It told me that my HD was unreadable, that it couldnt define the volume and so many other things. I was resolved to getting a new HD. I had my back up so I didn’t care. All of a sudden, my external HD started messing up, I couldn’t copy things from it and copy to it, did a lot of repairs till one day it didn’t come on. I tried opening it on another OS (Linux). For those that don’t know. There are times that windows would or can not open some flash drives or HD but other OS will be able. Anyways, it wasn’t showing on Linux. That was the end of the external HD. I started looking for my flash, and lo and behold it was missing. Apparently one of my friends “borrowed’’ it without asking. I asked him about my files, he said when he put the flash drive inside the USB port, that he got a message that prompted him to format and he did. I thought I was dreaming. I just went to bed immediately. Woke up the next day to find out that I wasn’t dreaming. I was becoming desperate, I called my friend that I backed up my files asking him how far, he gave me the final blow. He too had to replace his HD. I gave up. I lost over 450 GB worth of setups, documents, songs. Everything you could possibly think of. I had no choice but to start everything all over again. But I learnt my lesson and learnt other ways that I should have done and some other processes I skipped. I felt I should share with you.
ALWAYS SET A SYSTEM RESTORE POINT
Computers cant give you 100 percent efficiency, the best it can do is 99.999%. So you should be wary. By setting a system restore point, you can always set your system to the last time your computer was in a good condition. In case your system all of a sudden develops a fault.
BACK UP YOUR FILES
Always try to back up your files weekly or monthly or when you make important changes. You can never over back up your files. I have learnt additional ways apart from the conventional ones. First, put your files in a folder and zip it. After which send an email to yourself. So in case you need it, you can go to your inbox and download it from there (provided you don’t delete your box) and the next one is sky drive (which we will discuss much later). Finally, Google allows you to back up your files online. (Thank you Google).

ENSURE YOUR COMPUTER IS WORKING OPTIMALLY
Try not to go over a month without shutting down your system. Most of us are guilty of putting the system to sleep or hibernating or simply just closing the system. Make sure you do routine checks for example de-fragmentation, disk clean up and ensure your anti-virus is up to date.

I am sure you guys were expecting that since I told you about the different types of disasters, I should at least tell you how you can prevent them. Sadly the best you can do is detect them and react to them. You just have to pray that you are lucky.

Thanks for the reading.

Operating Systems (OS)

Top of the morning to everyone, first of all we will like to apologise to our readers for not releasing a post last weekend. Now,I guess that’s out of the way(please 😉 ) I guess we can move on to what we have for you today.

In this post, we will be discussing about Operating Systems, in short OS. I can hear lot of groans,like “we are not in school’’ or “this is not a lecture room’’or “I hope this is not another boring lecture’’. I can guarantee you after reading this, you will not have any complaints(I hope x_x).

First of all, what is an Operating System? In Computer Science, it is simply the basic software that controls a computer. It has three major functions:

-It tells computer hardware, such as computer memory, printers, disks, keyboard, mouse, and monitor what to do, how to do it and when to do it.
-It organizes files on a variety of storage media, such as floppy disk, hard drive, compact disc, digital video disc, and tape.
-It manages hardware errors and the loss of data.

Operating systems control different computer processes e.g. running a spreadsheet program like excel or accessing information from a computer’s memory. One very important function is interpreting commands, enabling the user to communicate with the computer.

Operating systems are of two categories: single-tasking and multitasking. The more primitive single-tasking operating systems could run only one process at a time. Take for example, when the computer is printing a document, it cannot start another process or respond to new commands until the printing is completed. (You can just imagine). Fortunately, advances in technology has changed that, all modern operating systems are multitasking and can run several processes simultaneously i.e. you can be preparing a document, copying files and at the same time be playing music on your computer.

I hope you are getting the picture. I am sure if asked to mention a type of OS, many will quickly respond saying: Microsoft Windows. True, it is, but there are others which are uncommon to a lot of people, especially in this part of the world, namely: UNIX, Macintosh (Mac), OS/2 etc.

In this post however, we will be focusing on just 3 types, namely: Microsoft Windows, Macintosh (Mac) and Linux.

Find below a brief history, applications and flaws about this operating systems

In the year 1969, at AT&T Bell Laboratories, UNIX was invented. It is a popular operating system among academic computer users. Its popularity rose due to the growth of the Internet. The Software for the Internet was initially designed for computers that ran UNIX.

Variations of UNIX include:

-SunOS (distributed by SUN Microsystems, Inc.),
-Xenix (distributed by Microsoft Corporation),
-Linux (available for download free of charge. and distributed commercially by companies such as Red Hat, Inc.).

UNIX and its clones support multitasking and multiple users. It consists of a file system that provides a simple means of organizing disk files and lets users control access to their files.

Another plus to this OS is the fact that it is really secure, and less prone to hacking, and it allows low level communication with the hardware, making it the geek’s preference. On the other hand the commands in UNIX are not readily apparent, however, and mastering the system is difficult. Although UNIX is popular for professionals, it is not the operating system of choice for the general public.

In 1984, the Operating system Macintosh was developed by Apple Computer, Inc.; it pioneered the use of a graphical interface which made the computer easy to operate for the novice user.
Mac OS can be divided into two families:

-The Mac OS Classic family, which was based on Apple’s own code
-The OS X operating system, developed from Mac OS Classic family

Apple is known for hiring the best industrial and interface designers around, and it shows in the intuitive nature of the GUI, if you have used an iPhone, iPad or iPod you will understand what I mean. Mac OS is a two-layered system, the attractive GUI sits atop a UNIX core. It’s simply impossible to install a destructive Trojan or virus unless the user explicitly allows it root access via typing in the admin password. On the other hand, all that flashy secure reliable power comes at a price. Macs cost more than machines that run other operating systems. Highly specialized software can be difficult to source for Mac OS, such as industry-specific applications. If you’re a computer gamer, Mac OS isn’t going to do it for you. Boot Camp and Parallels will allow you to run games natively in Windows, but there may be a performance hit. Some games are produced for Mac OS, but the number is very small.

In 1985, the Windows operating system was manufactured by Microsoft Corporation, providing users with a graphical user interface (GUI), which allows them to manipulate small pictures, called icons, on the computer screen to issue commands. Windows is the most widely used operating system in the world. It is an extension of and replacement for Microsoft’s Disk Operating System (MS-DOS). In Windows, the user can move a cursor around on the computer screen with a mouse. By pointing the cursor at icons and clicking buttons on the mouse, the user can issue commands to the computer to perform an action, such as starting a program, accessing or copying a data file.
Variants include: Windows- NT, 95, 98, 2000, XP, Vista, Windows 7 etc.

It is highly user friendly, and its software compatibility is high, making it the business man, gamer, and novice’s choice. On the other hand, it has the disadvantage of requiring more hardware—such as faster CPUs, more memory, and higher-quality monitors—than do command-oriented operating systems, and it is not the best when it comes to core security.

Future Innovations

Operating systems will continue to evolve. A recently developed type of OS called a Distributed OS is designed for a connected, but independent, collection of computers that share resources such as hard drives. In a distributed OS, a process can run on any computer in the network (presumably a computer that is idle) to increase that process’s performance.
Who knows what next is brewing in the labs in the world of OS, all we can do is wait and see.

Thank you for reading this post and God bless.

BLACKBERRY II- Headaches and Solutions

Happy weekend everyone. Hope your week wasn’t too stressful. I am pretty sure this weekend is pretty much for relaxing and watching soccer.  Anyways, I wouldn’t take much of your time with this post and we will be continuing from Last week’s post; Blackberry and this week we will be talking about different Operating Systems (OS), features and applications. So Lets go:

We all know, and for the sake of people that don’t know, when you purchase a blackberry, It comes with an OS (either 5 or 6) like in the older models and OS 7 in the newer models. Each OS can be upgraded, some to a different version for example; from OS 5.0.1 to 5.2.1 while other from OS 5 to OS 6. Apart from the OS, It also comes with Pre-installed applications and services. Pre-installed, in layman terms means it comes with the phone.

PRE-INSTALLED APPS AND SERVICES

DOCUMENTS TO GO®

Did you know that apart from using your blackberry to check and send e-mails,  you can Create and edit Word, Excel and PowerPoint docs, and view PDF docs anywhere, anytime from your blackberry?  If you knew, good for you. If you did not know, don’t feel bad. Simply go to Applications, and select Word to go for creating and editing a word document, Sheet to Go if you want to do some spreadsheet calculations and slideshow to Go for PowerPoint Presentations.

SOCIAL FEEDS

You can Stay up-to-date with your social networks and receive the latest news and information from your favourite blogs and websites through RSS feeds.

BBM

With BBM features built right into many of your favourite applications, you can share or chat with your BBM friends while you’re in the app.

BLACKBERRY id

Your BlackBerry ID is your master key to BlackBerry products, sites, services and applications

HEADACHES OF BLACKBERRY USERS

Most blackberry users always complain that their blackberry devices are slow or always hanging or both. Here are a few ways to make the frustration go away.

Check Your Device’s Available Space

It’s always a good idea to periodically check how much memory is left on your device. This is a fairly simple procedure. Here’s how:

For OS 6 and OS 7

Go to ‘Options’ > Scroll down to and select ‘Device’ > Scroll down to and select ‘Device and Status Information’ > Scroll down to ‘Device Information’ > your ‘Free Memory’ will be shown in bytes.

For OS 5 devices

Go to Options > Status > File Free tells you how much free space your device has in bytes.

Close Applications Running in Background

Often times, a device will lag because applications that weren’t closed down properly are still running in the background. Checking this regularly is also a great way to maintain speed and performance. Here’s how:

For OS 6 and OS 7 devices

From your home screen, press the BlackBerry button and select ‘Switch Application.’ You can also press and hold the BlackBerry button to get the same effect. As you can see below, this will display all of your applications that are currently running in the background. Go into each application and close them manually to ensure they are exited properly.

For OS 5 devices

From your home screen, press the BlackBerry button twice to display an options menu. From there, scroll down to ‘Switch Application’. This will display all applications that are currently running on your phone. Go to each application and exit from them properly.

Clear Your Event Log. Often.

Your BlackBerry stores everything. When you opened an app, when you closed an app, mobile websites you’ve visited, what you’ve downloaded, what you’ve deleted, etc. That’s a lot of information to be storing. Here’s a quick way to clear out all of that wasted space:

Hold down the ‘alt’ key and type ‘LGLG’ (lower case, without quotes). This will take you directly to your device’s Event Log. From there, press the BlackBerry button and select ‘Clear Log.’ This operation is the same for both OS 5 and 6.

Enable Automatic Memory Cleaning

For OS 6 and OS 7 devices

Go to ‘Options’ > Scroll to and select ‘Security’ > ‘Advanced Security Settings’ > Scroll to ‘Memory Cleaning’ > Select the box beside ‘Enable’ to enable regular memory cleaning.

For OS 5 devices

Go to ‘Options’ > Scroll to and select ‘Security Options’ > Scroll to and select ‘Advanced Security Options’ > Select ‘Memory Cleaning’ > You’ll see a drop-down menu, select ‘Enable’.

Clear Your Cache

Much like your desktop browser, you BlackBerry’s browser also stores content cache which can take up a lot of unnecessary space. It’s a good idea to do this often, depending on how much you use your BlackBerry for internet browsing.

For OS 6 and OS 7 devices

Open your browser > Press the BlackBerry button to reveal a menu > Select ‘Options’ > Scroll down to the bottom where it says ‘Clear Browsing Data’ (shown below) make sure the box beside ‘Cache’ is checked > Select ‘Clear Now’.

For OS 5 devices

Open your browser > Press the BlackBerry button to reveal a menu > Select ‘Options’ > Select ‘Cache Operations’ > Under ‘Content Cache’ you will see a ‘Clear’ button. Select ‘Clear’.

FAST BLACKBERRY BROWSER

It is the most powerful BlackBerry Browser to date, it supports HTML5 videos, and a page loads 40% faster than that of BlackBerry OS 6. That is to say, if it takes 10 seconds for a page to load on OS 6, it will take approximately 6 seconds to load on OS7. Amazing right?

 

CONNECTIVITY

Have you ever being in a situation when you need Internet services desperately and you can’t seem to find a Wi-Fi Hotspot? Now you can simply turn on Mobile Hotspot on your BlackBerry Smartphone, found under Manage Connections, and create a hotspot.  Pretty convenient yeah? You can then share it by connecting up to five Wi-Fi devices at once and also make calls over Wi-Fi instead of using your plan’s minutes 😉

BLACKBERRY!!!!

Hello. Hope the weekend is going well for you. For football lovers, a week to the epl. But hey that isn’t why we are here, Lets come back home. This week, we shall be talking about blackberry. I am pretty sure a lot of you must have repeated the word “Blackberry “and asked yourself “What else can they teach me about my blackberry”. Please keep on reading, I can guarantee that you will learn something new at the end of the post.

 

BlackBerry as we all know is a Smartphone; it is designed by Research In Motion (RIM). RIM produced the first BlackBerry phone in 1999 and the latest Os 7 devices were announced in the summer of 2011.

BlackBerry devices are smartphones, which are designed to function as personal digital assistants, portable media players, internet browsers, gaming devices, cameras and much more. They are basically known for their ability to send and receive (push) email and instant messages while maintaining a high level of security through on-device message encryption. BlackBerry devices support a large variety of instant messaging features, with the most popular being the proprietary BlackBerry Messenger service.

BlackBerry accounted for 3% of mobile device sales worldwide in 2011, making its manufacturer RIM the sixth most popular device maker and 25% of mobile device sales are smartphones. The consumer BlackBerry Internet Service is available in 91 countries worldwide on over 500 mobile service operators using various mobile technologies. As of October 2011, there were seventy million subscribers worldwide to BlackBerry. In 2011 the Caribbean and Latin America, had the highest penetrations of BlackBerry smartphones worldwide, with up to about 45 per cent in the region having a RIM device. Nigeria is now one of the heavy users of BlackBerry smartphones .

Modern GSM-based BlackBerry handhelds incorporate an ARM 7, 9 or ARM 11 processor(a new type of processor), while older BlackBerry 950 and 957 handhelds used Intel 80386 processors. The BlackBerry models called “Torch” (Torch 9850/9860, Torch 9810, and Bold 9900/9930) have  1.2 GHz MSM8255 Snapdragon processors, 768 MB system memory, and 8 GB of on-board storage, also all BlackBerry smartphones after OS 5 support up to 32 GB microSD cards.

All original BlackBerry devices have blue seals located on different parts of the Smartphone (basically on the screws) depending on the model of the Blackberry. The touch, tour, javelin and curve series have there’s on a screw at the back just beside the phone battery. While for the bold series, it is located under a small piece cover below the keypad.

The BlackBerry smartphones can be used faster with the availability of shortcuts. Depending on the typing input language that you are using, some shortcuts might not be available.

To change your ring tone, from the Home screen, press the Send key. Press the Menu key. Click Set Ring Tone.

To check your voice mail, press and hold 1.

To send an incoming call to voice mail, press and hold the Volume Down key on the right side of your BlackBerry device.

To set up speed dial for a contact, on the Home screen or in the phone application, press and hold the key that you would like to assign speed dial to.

To add an extension to a phone number, press the X key. Type the extension number.

To type a letter in a phone number field, press and hold the Alt key. Use the multi-tap input method to type the letter.

To insert a plus sign (+) when typing a phone number, press and hold 0.

To turn on the speakerphone during a call, press the period (.) key. To turn off the speakerphone during a call, press the period (.) key again.

If you are using a wireless headset, to stop listening to a call with the headset, press the period (.) key. To listen to a call using the wireless headset again, press the period (.) key again.

PROCESSORS

Good day everyone, I apologise for the abrupt end to last week’s post. But as promised this week, we will be talking about processors, different types and how to care for them.

From last week’s post, we learnt that there are mainly two types of processors which are manufactured by two companies namely Intel and AMD. They come in different variations. The Intel family includes Pentium Dual Core, Core 2 Quad, Intel Pentium 2 Dual Core Processor and the likes while AMD processors include AMD Athlon, AMD Athlon 64, AMD Athlon X2, AMD Athlon Xp, AMD Duron, AMD Sempron, and so on.

This does not mean that these are the only two processors we have; for example, the new Windows 8 tablets will be running on ARM processors as Well.

The biggest flaw with Intel’s low-end offerings is that the Pentium family limits you to dual-core configurations. Our concern is that outside of a game, you are going to find situations where the two cores hurt performance in other applications while for that of AMD, because of the larger number of processor than the Intel. It tends to generate more heat which if not properly managed can damage the processor.

But Wait, What exactly is a processor and what does it do and what does it look like?

           

The processor is the most important part of a computer system. A large number of individuals, Novices, computer users and even some computer professionals alike, do not know this simple fact, yes most of us say it’s the central processing unit, we are quite right, but most  people even get the idea of the central processing (CPU)  unit all wrong. We look at the computer components and what we term as CPU is just a casing which houses or contains the processor or CPU itself along with other supporting components.

This processor or otherwise known as Brain Box is where all the calculations and works of the computer system take place. There are two components of the CPU connected by a kind of electronic roadway called a bus. We have the control unit (CU), which tells the rest of the computer how to carry out a program’s instruction and also we have the Arithmetic/logical unit, as the name implies it handles all arithmetic and logical operations and controls the speed of those operations.

Another components of a CPU that are vital to its operation are the registers, which are very small memory locations that are responsible for holding the data that is to be processed.

On very large computers, the CPU may consist of many chips mounted on a series of printed circuit boards, but on most personal computers, the CPU is housed in a single microprocessor chip that is installed on the system board in a slot or socket.

Now, the speed of the processor has a lot to do with the overall speed and efficiency of the computer system as a whole, the higher the speed, the faster the system. And as we all know (well, most of us, I think), speed is measured in hertz (Hz), you know, KHz, MHz, GHz and all that. So a system wit processor speed 2GHz is faster and more efficient than one of 1.8GHz. Though the RAM of a system also has a part to play in the efficiency and speed of the system because they work together (but hey, we r talking about the processor here so lets stay focused. Thank u. :D). Don’t worry other components will be discussed subsequently.

Care for the processor

The operation of the processor brings about a lot of heat, so the major care I would propose for the processor is to always ensure that the fan which cools the processor during its operation is always in good condition, because without this, the processor overheats, burns up and is damaged and a damaged processor as a result of burning can not be repaired. Also make sure the heat-sink which is placed very close to the processor has noting blocking it from doing the work it was made for, that’s conducting heat away from the processor.

Also most of us are fond of using our systems (in this case laptops) on beds, sofas and soft surfaces, this impairs the cooling of the processor, because the air vents are blocked hereby allowing little or less ventilation into the processor areas, also resulting in over-heating and eventual damage. So on this note, it is advisable to place your laptop on very hard and smooth surfaces, or place on external CPU cooling fans.

And here folks, marks the end of this weeks post, for more information, questions and suggestions on the processor, feel free to contact us

TIPS ON BUYING A LAPTOP

Good day everyone, we decided to take a break from our posts on ICT4d and delve in matters that concern an average person and that is the issue of buying and selling. As we all know, the world today is a global market. It is either you are buying and selling a merchandise or services. Before a sale or purchase is to be made, information about the product/services should be obtained. For this post we will be looking at buying a laptop and things you must know before making that purchase before in the long run it becomes an expensive purchase.  Shall we continue?

First of all, you have to identify the need/purpose of the laptop to be purchased.

Will it be handling critical graphic works? Will it be just a business laptop or for entertainment (Gaming included)? After the need has been identified. You can move to the next thing you should do/have

Secondly, have a budget. Always set a minimum and maximum amount for every item.

This is quite straightforward and should be the norm. But you will be amazed at the amount of people that ignore this and as a result you end up with either spending too much or too little on the system. Let me share an example with you, if you have the money to get a system for 150,000. Hold an extra amount in case you see a system that will be far better than the one you originally thought to buy. It will save you the journey of coming back the second time.

Thirdly, do not only visit one shop before buying the system.  Expand your options; you don’t know if you will get a better deal somewhere else. Try 3-5 different places and get more information about the system. Information like the model, where they are made from, the specification and so on. Every laptop has a unique product number in addition to the various models. You can check online for more information about the system by just entering the product number.

More on the model of the system and where they are made from. Everybody thinks that all laptops are the same. There is a difference no matter how irrelevant you may think it is. Some last longer than others. Some are just cheap and after a few months they will give you problem. We have different models of laptops: Dell Hp, Toshiba, Compaq, Acer, Samsung.
In addition to everything being said, laptops are produced from different areas of the world. With the ones made from US/UK ranking first. So for quality, they are preferred.
Finally, the specifications of the system shouldn’t be ignored. I mean the size of d HDD, d ram, d processor, battery, screen size, graphics card, wireless, n keyboard.  This is when your need has been identified. The first and last points work hand in hand. The size of the HDD. HDD stands for harddisk drive and this is most vital. If you know that you are not going to be using much of the system. I will advise a 250GB HDD. But if you intend to do a lot of reading, gaming etc. I will advise u do a 320 n sometimes 500GB.
The RAM. RAM stands for random access memory. In plain English, it is the reason your system starts up when you put it up. If you are using the system to type then a 2GB ram. Sometimes 3GB will do, but if it will handle a lot of applications (gamin n all). Start with a 4GB RAM system.
The processor, this will be explained fully in one of our next post.

In conclusion, basically there are two types of processors which are manufactured by two companies and they are Intel and AMD. Now there are a number of varieties available in both Intel and AMD.

Intel offers Pentium Pro, Pentium II, Celeron, Pentium II Xeon, Pentium III, Pentium II and III Xeon, Celeron with Pentium III Based, Pentium 4, Pentium M, Intel Core, Dual Core Xeon LV, Intel Pentium Dual Core, Intel Core 2. Pentium Duo, Pentium Dual Core, Core 2 Quad, Intel Pentuim 2 Dual Core Processor.
AMD processors include AMD Athlon, AMD Athlon 64, AMD Athlon X2, AMD Athlon Xp, AMD Duron, AMD Sempron, AMD Turion, MD Opteron and AMD Phenom 1. Newer processors are out already. Like the core I3, I5, I7.

The biggest flaw with intel’s low-end offerings is that the Pentium family limits you to dual-core configurations. Our concern is that outside of a game, you are going to find situations where the two cores hurt performance in other applications.

Thanks for reading.

ICT4D-APPLICATION,ADVANTAGES AND DISADVANTAGES

THE APPLICATION, ADVANTAGES AND DISADVANTAGES OF ICT4D

In our last post, we defined ICT4D as Information Communication Technology for Development. Now we look at the applications and benefits.

Applications

One might wonder, why delve into ICT? Does it add money to my pocket? How can I benefit from it and many more puzzling questions? Let us glance through some of the numerous applications of ICT4D.

ICTs are powerful tools for extending educational opportunities, both formal and non-formal, to the general populace either in scattered and rural populations or metropolitans, groups traditionally excluded from education due to cultural or social reasons, and the elderly, as well as all others who for reasons of cost or because of time constraints are unable to enrol on campus.

ICT4D can also be of great help to other sectors, apart from the education sector but in this post we started to focus mainly on education. Students, Parents, Individuals, Government as a whole can all benefit from ICT. Some of ways they can be of help are highlighted in different sections.

Gains for teachers

·         Gains in ICT literacy skills, confidence and enthusiasm.

·         Easier, better and faster planning and preparation of lessons and designing materials

·         Students are generally more ‘hands on’ and are more willing to work when they use computers than when they are given other tasks to do.

·         Computer use during lessons encourages after-school learning among students

Gains for students

·         Development of writing skills (including spelling, grammar, punctuation, editing and re-drafting), also fluency, originality and elaboration.

·         It increases self-confidence and self-esteem of the students

·         Students prefer learning in a technology-enhanced setting than in a traditional classroom

·         Broadband technology supports the reliable and uninterrupted downloading of web-hosted educational multimedia resources

Gains for parents

·         Easier communication with teachers and the school

·         Increased involvement in education for parents and, in some cases, improved self-esteem

·         Increased knowledge of children’s learning and capabilities, owing to increase in learning activity being situated in the home

ADVANTAGES OF ICT4D

• Anytime, anywhere you go. Just like MTN’s slogan is anywhere u go, u can get materials online anytime regardless where you are, hence “anytime, anywhere you go.  One defining feature of ICTs is their ability to blend the two concepts time and space. ICTs make possible asynchronous learning, or learning characterized by a time lag between the delivery of instruction and its reception by learners. Online course materials, for example, may be accessed 24 hours a day, 7 days a week. ICT-based educational delivery (e.g., educational programming broadcast over radio or television) also dispenses with the need for all learners and the instructor to be in one physical location.

•  Access to remote and online learning resources.  Teachers and learners no longer have to rely solely on printed books and other materials in physical media housed in libraries (and available in limited quantities) for their educational needs. With the Internet and the World Wide Web, a great wealth of learning materials in almost every subject and in a variety of media can now be accessed from anywhere at any time of the day and by an unlimited number of people. This is particularly significant for many schools in developing countries, and even some in developed countries, that have limited and outdated library resources. ICTs also facilitate access to resource persons, mentors, experts, researchers, professionals, business leaders, and peers—all over the world.

·         ICTs help prepare individuals for the business environment.

One of the most commonly cited reasons for using ICTs in the classroom has been to better prepare the current generation of students for a workplace where ICTs, particularly computers, the Internet and related technologies, are becoming more and more ubiquitous. Technological literacy, or the ability to use ICTs effectively and efficiently, is thus seen as representing a competitive edge in an increasingly globalizing job market.

Disadvantages of ICT

One of the major barriers for the cause of ICT not reaching its full potential in the foundation stage is teacher’s attitude. In theory some people may have the opinion that the teachers who had not experienced ICT throughout their learning tend to have a negative attitude towards it, as they may lack the training in that area of the curriculum.

Another important drawback to using ICT in schools is the fact that computers are expensive. According to the IT learning exchange (2001), in most schools ICT will be the single largest curriculum budget cost. This may be seen as a good thing but on the other hand there will be little money left over for other significant costs but on the plus side, cheaper tools are being introduced reading tablets ( kindle,nexus 7 etc)

ICT4D

Introduction – what is ICT4D?

 

Hey, am sure you are all wandering what Quadclover is and what is it all about? Here is an insight.

Quadclover is an ICT4D Company. Most of our readers are familiar with the acronym ICT. For those that are relatively green in IT. ICT stands for Information Communications Technology. So everybody can second guess what ICT4D is. It is ICT concatenated with -for development (information communication technology for development)

 

Lets focus on the words ICT4D:

– INFORMATION
-COMMUNICATIONS
– TECHNOLOGY

– DEVELOPMENT

 

A good way to think about ICT4D is to consider all the uses of digital technology that already exist to help individuals, businesses and organisations use information and discovering new ways on which the technology can be improved upon.

 

ICT4D covers any product that will store, retrieve, manipulate, transmit or receive information electronically in a digital form. For example, personal computers, digital television, email, robots.

 

So ICT4D is concerned with the storage, retrieval, manipulation, transmission or receipt of digital data. Importantly, it is also concerned with the way these different uses can work with each other.

 

In business, ICT4D is often categorised into two broad types of product: –

 

(1) The traditional computer-based technologies (things you can typically do on a personal computer or using computers at home or at work); and

(2) The more recent and fast-growing range of digital communication technologies (which allow people and organisations to communicate and share information digitally)

 

Let’s take a brief look at these two categories to demonstrate the kinds of products and ideas that are covered by ICT:

Traditional Computer Based Technologies

 

These types of ICT include:

Application Use
Standard Office Applications – Main Examples
Word processing E.g. Microsoft Word: Write letters, reports etc
Spreadsheets E.g. Microsoft Excel; Analyse financial information; calculations; create forecasting models etc
Database software E.g. Oracle, Microsoft SQL Server, Access; Managing data in many forms, from basic lists (e.g. customer contacts through to complex material (e.g. catalogue)
Presentation software E.g. Microsoft PowerPoint; make presentations, either directly using a computer screen or data projector. Publish in digital format via email or over the Internet
Desktop publishing E.g. Adobe Indesign, Quark Express, Microsoft Publisher; produce newsletters, magazines and other complex documents.
Graphics software E.g. Adobe Photoshop and Illustrator; Macromedia Freehand and Fireworks; create and edit images such as logos, drawings or pictures for use in DTP, web sites or other publications
Specialist Applications – Examples (there are many!)
Accounting package E.g. Sage, Oracle; Manage an organisation’s accounts including revenues/sales, purchases, bank accounts etc. A wide range of systems is available ranging from basic packages suitable for small businesses through to sophisticated ones aimed at multinational companies.
Computer Aided Design Computer Aided Design (CAD) is the use of computers to assist the design process. Specialised CAD programs exist for many types of design: architectural, engineering, electronics, roadways
Customer Relations Management (CRM) Software that allows businesses to better understand their customers by collecting and analysing data on them such as their product preferences, buying habits etc. Often linked to software applications that run call centres and loyalty cards for example.

Traditional Computer Based Technologies

The C part of ICT refers to the communication of data by electronic means, usually over some distance. This is often achieved via networks of sending and receiving equipment, wires and satellite links.

The technologies involved in communication tend to be complex. You certainly don’t need to understand them for your ICT course. However, there are aspects of digital communications that you need to be aware of. These relate primarily to the types of network and the ways of connecting to the Internet. Let’s look at these two briefly (further revision notes provide much more detail to support your study).

 

 

 

Internal networks

Usually referred to as a local area network (LAN), this involves linking a number of hardware items (input and output devices plus computer processing) together within an office or building.

The aim of a LAN is to be able to share hardware facilities such as printers or scanners, software applications and data. This type of network is invaluable in the office environment where colleagues need to have access to common data or programmes.

 

External networks

Often you need to communicate with someone outside your internal Network; in this case you will need to be part of a Wide Area Network (WAN). The Internet is the ultimate WAN .

ICT in a Broader Context

Your ICT course will almost certainly cover the above examples of ICT in action, perhaps focusing on the use of key applications such as spreadsheets, databases, presentation, graphics and web design software.

 

It will also consider the following important topics that deal with the way ICT is used and managed in an organisation:

– The nature of information (the “I” in ICT); this covers topics such as the meaning and value of information; how information is controlled; the limitations of ICT; legal considerations

– Management of information – this covers how data is captured, verified and stored for effective use; the manipulation, processing and distribution of information; keeping information secure; designing networks to share information

– Information systems strategy – this considers how ICT can be used within a business or organisation as part of achieving goals and objectives
