Components Of Computer Essay
A Computer is a programmable electronic device designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations. Mainframes, desktop and laptop computers, tablets, and smartphones are some of the different types of computers.
2. Here are the Basic Components of a Computer:
a) Input Unit - Data and instructions must enter the computer system before any computation can be performed on the supplied data. The input that links the external environment with the computer system performs this task. Data and instructions enter inputs in form that depend upon the particular device used. For example, data is entered from a keyboard in a manner similar to typing, and this differs from the way in which data is entered through a mouse, which is another type of input device. However, regardless of form in which they receive their inputs, all input devices must provide a computer with data that are transformed into the binary codes that the primary memory of the computer is designed to accept. This transformation

The very high end systems of this range are used for graphics-intensive work.
c) Mainframes - A large computer system which is used by a lot of users at the same time, like the central system of a corporate office. These computers have multiple processors and very different architecture from ordinary PCs to serve a number of users at the same time. Processing power is very much greater than PCs.
d) Supercomputers - The fastest computers available at a particular period of time are generally the supercomputers. They are similar to mainframes but generally are reserved for single complex calculation (e.g. DNA Analysis) which require a 'huge' amount of processing power. The architecture of supercomputers vary according to the purpose they are built
