A computer is any machine that can be programmed to carry out a set of algorithms and arithmetic instructions. In terms of construction, each of these main components are attached to the motherboard and then put into a protective case—resembling the clean, polished look most of us are accustomed to seeing. Sure, most computers have their own distinct design - and different brands of hardware installed - but the components listed above are standard across all computers.

Computer: A computer is a combination of hardware and software resources which integrate together and provides various functionalities to the user. Hardware are the physical components of a computer like the processor, memory devices, monitor, keyboard etc. There are a few basic components that aids the working-cycle of a computer i.

The 5 different parts of a computer—taking a look under the hood

The physical components of a computer constitute its Hardware. These include keyboard, mouse, monitor and processor. Hardware consists of input devices and output devices that make a complete computer system. Examples of input devices are keyboard, optical scanner, mouse and joystick which are used to feed data into the computer. Output devices such as monitor and printer are media to get the output from the computer. A set of programs that form an interface between the hardware and the user of a computer system are referred to as Software.

Computer Hardware

Introduction to Computing. The internal architectural design of computers differs from one system model to another. However, the basic organization remains the same for all computer systems. Data and instructions must enter the computer system before any computation can be performed on the supplied data. The input unit that links the external environment with the computer system performs this task. Data and instructions enter input units in forms that depend upon the particular device used.


Computer Components: (1) Scanner: An input device that can convert the contents of a paper document into a digital image that can be stored in the computer.


What are the Basic Computer Components?

Digital computer , any of a class of devices capable of solving problems by processing information in discrete form. It operates on data, including magnitudes, letters, and symbols, that are expressed in binary code —i. By counting, comparing, and manipulating these digits or their combinations according to a set of instructions held in its memory , a digital computer can perform such tasks as to control industrial processes and regulate the operations of machines; analyze and organize vast amounts of business data; and simulate the behaviour of dynamic systems e. A brief treatment of digital computers follows. For full treatment, see computer science: Basic computer components.

Computers internal architectural design comes in different types and sizes, but the basic structure remains same of all computer systems. Devices that are not integral part of CPU referred to as peripherals. The below section describe briefly all the computer components in a computer system. All the input unit devices provide the instructions and data are transformed into binary codes that is the primary memory acceptable format. Memory or Storage unit is used for storing Data during before and after processing.
