Definition of computer? Computer is a calculating and electronic device that accept data and instructions as input and uses the instructions to process and transform data into information.

Parts of computer and their functions. 1) C.P.U. 2) Monitor 3) Mouse Functions:- C.P.U= C.P.U. is the brain of computer. It controls the monitor. Monitor; Monitor is used to see different things which are in computer. Mouse; mouse is used to move the cursor bar and used to search many things which are loaded in computer.

Components of computer Components of computer are Input device, System unit, and out put device Input device is are the devices that are used to provide input to a computer for processing some commonly input device are input devises are keyboard and mouse System input are three parts are i)M.U ii) A.L.U iii) C.U Out put device are the device that are used to display or print the results of data processing performed by a computer. Some commonly used output devices are i) V.D.U. ii) Printer

Hard ware and software Hardware refers to does components of a computer that can be physically and touched Example are:- Printer, keyboard, mouse, and the chips , diodes, wires etc Software represent the set of program that make the computer work Example are :- Windows 98, MS Word, MS PowerPoint etc

Applications of computer Computer have became an integral part of our every day life. It is very difficult to imagine a world without them. Applications of computer lies in the i) High speed, Accuracy, versatility, consistency and large storage that characterize computer ii) Their ability to work non-stop without together.
