Computer System (IPO)

·         Computer System

-          Computer is an advanced electronic device which takes raw data as input then processes these data as proven instruction then gives output and stores it for future use. It is a data processing machine, which can process any kind of numerical and nonnumeric operation under the control of sequential instructions called program. In other word any electronic machine that can perform their work 'IPO' cycle is know as computer.

IPO CYCLE:

INPUT                                                   PROCESS                                                                     OUTPUT

(Raw data)                                          (Unseen)                                                                             (Result)

(Input Device)                            (Processing device)                                                              (Output Device)

1)      INPUT:

-          Input is the raw information. It is the collection of facts or figures or both. It is done through input devices. eg. through mouse, keyboard.

2)      PORCESS:

-          Process is the manipulation of data as per give instruction. It is done through Central Processing Unit

3)      OUTPUT:

-          Output is the processed data. It is also called result and displayed though Output device like monitor , printer.
