Computer is an advanced electronic device,which takes raw data as input from the user and processes these data under the control of set of instruction, and gives the result .it also saves output for the future use. it can process both numerical and non-numerical calculations. the working principle of computer can be summarized input,process and output cycle.
1.input=input is the raw information entered into a computer from the input devices.it is the collection of letters, numbers,images etc.keyboard,mouse,scanner,digital/web camera,joystick etc.are some of the input devices.
PROCESS=process is the operation of data as per given instruction .it is totally process of the computer system.CPU(central processing unit)is the main processing devices.
2.OUTPUT=output is the processed data given by computer after data processing.output is also called as result.we can save these result in the storage devices for the future use.monitor(screen)and printer are the major output devices.
