Random Access Memory or RAM – this allows your computer to read data faster, thus a higher ram accelerates the speed of your computer system the capacity of which is measured in gigabytes. A 2 gigabyte ram or 2GB can already provide a good speed for your computer system.

Hard Disk Drive – this is the hardware that stores the primary information and data. So even if you do basic tasks only, you will still be collecting an assortment of data that you would want to keep and logically, your stored files will continue to increase through time.

Choose a hard disk that has at least 160 GB to ensure a large capacity for storage. External hard drives are also available should you need more space for storage of large files including your back-up files. You can ask your computer store about this when buying computer components.

Central Processing Unit – also called as the microprocessor is the brain or your computer where the functions of a program are executed. The CPU triggers your operating system that boots your computer. Most microprocessors are manufactured by Intel and AMD, but Intel continues to be the more popular choice.

When buying computer components such as your CPU, you look at the clock speed, the cache memory and the bus speeds. These factors determine respectively how fast your computer will run, how much data can be stored, and the speed your CPU executes in transferring data to and from the other components. For basic computer tasks, an Intel Dual Core is usually recommended.

Mother Board – this is where most of the major components of your computer are embedded such as the microprocessor, memory cards, video card, power supply, drive connectors and other computer components. The type of mother board is essential when buying computer components because you need to choose one that will allow you to upgrade the peripherals installed on it.

Video/Graphic Cards – this computer hardware is very important for gaming and for video and graphic uses because it is the component that processes image data that comes out on your monitor.

You can choose from the less expensive 2D graphic images or you can go for the latest output of 3D images. A highly recommended graphic card is the nVidia 1GB graphic card with an Asus motherboard and a hard disk capacity of 500GB which you can specify when buying computer components.

Things To Consider When Buying A Computer

1. Budget:

The first thing that most of us are constrained to is budget so this is the first thing you should consider. We always want the best but we need to be grounded on what we can afford. So Get a budget and stick to it.

2. Computer brand:

when buying a new computer the second thing that should come into your mind should be what brand of computer do I want to buy. Brand of a computer is determined by some fact like brand popularity, brand durability and availability of parts in the market.

3. Facilities available:

You also have to consider the facilities that you want the computer to have, facilities like wireless enabled, Bluetooth, camera, card reader etc.

4. Memory (RAM)

Memory is the term used for how much information a computer can temporarily store. This factor is typically used when you multitask a lot. If you multitask on your computer a lot, then a lot of memory is essential to a speedy computer. Computers these days typically range from 1 GB to as much as 8 GB.

5. Hard disk:

The next fact to consider is the size of the hard disk drive. Using large amount of hard disk is the best since some part of the hard disk is assigned to the ram to enable it perform effectively. If you use small size of hard disk and some part is assigned to the ram you will be left with a very small size that makes your computer run slowly. So large hard disk size is the best.

6. Processor speed:

Another fact to consider is the speed of the processor: you will notice that within the last two years there has been tremendous competition between processor manufacturers. So there are various kinds and types of processor. There are two major processor manufacturers which are Intel and AMD so you have to make your choice based on your research. You have to get a pr

7. Graphics Card: The first question to ask is – Does the computer have a graphics card? A majority of computers don’t actually have a card dedicated to graphics processing, they simply use the main processor and RAM to power the visuals. However, if the computer does have a graphics card, there are several things to consider.
1. How many gigabytes does the graphics card support?
2. Is it ATI or Nvidia? – The two companies are contemporaries, but each has its strengths and weaknesses.
3. What level of processing power does it have? Not all graphics cards are created equal, so make sure to research the model of the graphics card to make sure you’re not overpaying.
