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
