Computer Full Form
C=CommonO= Oriented
M= Machine
P= Particularly
U= United and used under
T= Technical and
E= Educational
R= Research
To work computer properly there is need of both hardware and software.without hardware software not works and without software hardware will not work. Software always gives commands for hardware to work.
CPU of Computer is connected to various hardwares. All the controling and synchronization between these devices is done by system software that means operating system.
Functions of Computer
Computer functions are processing as follows
(Input) → (Processing) →(Output)
1. For input in computer we uses input devices like keyboard , mouse it provides commands to computer through software.
2. In this stage commands which are provided by input units are processed by processor through the software guidelines.
3. In last and third stage all the processed information is given for output.which will be available through output devices
Main Parts of Computer
