basic components of computer system

Input Unit  Input is any data or instructions entered into the memory of a computer … Apart from these elements, a computer system comprises of three basic components. Software is held either on your computers hard disk, CD-ROM, DVD or on a diskette (floppy disk) and is loaded (i.e. If the same program can run on two different computer brands they are said to be compatible. The hardware components of a computer system are the electronic and mechanical parts. Registers are a group of cells used for memory addressing, data manipulation and processing. The power supply unit in a computer converts the power from the wall outlet to the type of power needed by the computer. Here is some common hardware that you might find connected to the outside of a computer, although many tablets, laptops, and netbooks integrate some of these items into their housings: Monitor. The CPU is the brain of any computer system. These steps should follow in some order in fixed intervals of time. An information system is described as having five components. Output Unit. (function(d) { 'https' : 'http'; s.src = p + "://api.content-ad.net/Scripts/widget2.aspx?" All activities in the computer system are composed of thousands of individual steps. All the data to be processed and the instruction required for processing (received from input devices). We will discuss the following: Motherboard (this does something with the data to make it useful information) Processor (central processing unit) As name indicates, this part of CPU extracts instructions, performs execution, maintains and directs operations of entire system. The most essential hardware components are Motherboard, CPU, RAM memory, IO system, power supply, video display controller, Bus and hard disk drive. It controls the operation of all parts of the computer. Control unit performs following functions −. These intervals are generated by the Clock Unit. In a human body, all major decisions are taken by the brain and the other parts of the body function as directed by the brain. It consists of two components: Arithmetic Logic Unit (ALU), and Control Unit. It supplied information and results of computation to the outside world. It manages and coordinates the entire computer system. Storage or computer memory is the essential component of system where data, information’s and instructions are stored temporarily or permanently. Although, it does not perform any actual processing on the data, the control unit acts as a central nervous system for the other components of the computer. All calculations are performed and all comparisons (decisions) are made in the ALU. The software components of a computer system are the data and the computer programs. + qs; d.getElementById("contentad409348").appendChild(s); })(document); //-->// >
