PARTS AND ELEMENTS OF A COMPUTER
Here we want to lack at the electrification of computer into two parts:
The hardware
The software
A. HARDWARE
This is the term use to describe the various mechanical and electrical parts that add up to make a computer. These parts include:
I. INPUT DEVICE: After data have been fed into the computer they are automatically converted into electrically impulses and them routed to the main store where they are held until when needed. It is also called the memory or case store, the main store serves as a link to other units.
II. CONTROL UNIT: The instruction are assessed and interpreted by the control units, which send some signals or command to other components of the computer.
III. ARITHMETIC AND LOGICAL UNIT: In accordance with instruction, data is transferred from the main store to the ALU, where arithmetic and logic operations are performed such as computation, decision, etc.
IV. OUTPUT DEVICE: Processed data is routed from the main store where they are held for further processing, to the output devices after being recorded in an output medium such as the printer or VDU.
V. BARKING STORE: Data that are not meant for immediate use are kept in the barking store. It is a kind of supplementary store o the main store.
VI. STORAGE: The storage in the CPU is referred to as main storage, a term used to designate all internal storage of the CPU. It is the component of a computer into which al data processed by the computer are stored. The internal storage consist of magnetic cores arranged so that numeric and alphabetic characters and special characters such as comma, or a Naira sign (N) can be recorded in a storage and assessed When needed. Storage is divided into location normally consisting of a set of eight magnetic cores each 8-bits set of cores has an address, and the address of the storage location must be known either to the programmer or to a control program to store data in and read data from a location.
