Computer Assembly

Assemble Your PC

To build your PC from scratch you will need to purchase all the necessary hardware. The first thing you must consider before you start to shop around for your PC hardware is the specification of the hardware. You should think about what you are going to use your PC for, before buying fancy expensive hardware. Otherwise you will end up buying hardware which offers advance features that may not be necessary for your needs and end up wasting your money. For example, you may be using your PC for word-processing, spreadsheet and browsing the web. You would not gain much benefit by purchasing an advance 3D graphics card or having a top of the range processor. A simple graphics card and a mid-range processor will satisfy your needs.

Computers Generation

Features of different Computer Generations
First Generation Computers:
The First Generation Computers was marked by the use of vacuum tubes for the electronic components and by the use of electrostatic tubes or mercury delay lines for storage. Examples of first generation computers are EDSAC (1949), EDVAC (1951) etc., this generation lasted until the end of the 1950s and the computers in this era had their basis in wired circuitry and thermion valves. Their outstanding features were:-
1. Very expensive, poor reliability, slow input/output.
2. Quite large, generated lot of heat and required special housing.
3. The medium of internal storage was magnetic drum.
4. Punched cards and paper tapes were used for secondary storage.
5. Continuous maintenance is required; produces lot of heat hence requires special air conditioning.
6. Applications-pay roll and other single applications in large companies.
7. Uses batch processing technology, to process the data.

The input unit consists of one or more input devices. Keyboard is the one of the most commonly used input device. Other commonly used input devices are the mouse, floppy disk drive, magnetic tape, etc. All the input devices perform the following functions.
