Parts of Computer

As written earlier, computer is basically a combination of various devices and these devices are either the output devices or the input devices some of these input and output devices are mentioned here:-

Keyboard :-

it is the input device that is used to type something either alphabetic or numeric on the computer screen and to save it or to play music or to watch the videos in the case of multimedia keyboard.

the usage of a device depends on the purpose for which you are using a computer, besides these devices, there is a main part in the computer that functions as the brain of the computer known as the C.P.U or the central processing unit that consists of a power unit, a C.P.U fan and a hard disk and two RAM slots that look somewhat like a T.V. video game c.d. slots and the ram chip looks somewhat like that T.V. video game chip only. When all these parts are assembled together and plugged with their respective wirings, a computer starts working.

The working of ram is just to make the computer fast and to enhance a faster downloading and to let the user use multiple applications at a single time and to make the game playing more faster and video playing and calculations more efficient . The hard disk is used to store the data including the software’s and songs and movies etc. the better the memory power of a computer, the better gets its accuracy and efficiency. The power of a computer depends on the processor or the generation of the computer also.
