Computer Operations Paper

IntroductionComputers are an electronic device used for data processing, monetary fund and produce an turnout to the user. Based on the functionalities of the calculating car, the hardware components shadower be classified into four main units. Input Unit, widening Unit, Central process Unit, Memory Unit. These units are interconnected by minute electrical wires to permit communication surrounded by them. This allows the computer to function as a system.

Input UnitA computer uses stimulus devices to accept the data and program. Input devices allow communication between the user and computer. In newfangled computers keyboard, mouse, light pen, touch class etc are some of the gossip devices.

Output UnitSimilar to input devices, output devices have an interface between the computer and the user. These devices take machine coded output results from the processor and convert them into a form that apprise be used by humane beings. In modern computers, monitors and printers are the commonly used output devices.

Central Processing UnitCPU is the brain of any computer system. It is just like the human brain that takes all major decisions, makes all sort of calculations and directs divergent parts of the computer function by activating and lordly the operation. It consists of arithmetic and logic units, control unit and internal memory (registers). The control unit of the CPU coordinates the action of the entire system.



Programs (software) support the CPU, a set of instruction to follow and perform a specific task. Between any two components of the computer system, in that respect is a pathway called bus which allow for the data broadcast between them.

Control unit controls all the hardware operations, i.e., those of input units, output units, memory unit and the processor. The arithmetic and logic units in computers are capable of performing addition, subtraction, division and multiplication as well as some logical operations. The...
