• Input Devices
· Processing Device
• Output Devices
• Storage Devices
• Input Devices
The data that is given to the computer is called Input. Input
devices arc used to input data and instructions into the
computer. These devices send this data to the Processing
Unit.
•
CamC!B.
• PROCESSING DEVICE
The Processor is used to process data. It is also called Central
Processing Uni1(CPU). It is the brain of the compu1cr. It consists of
clcc1ronics circuit CPU interprcls and cxt.'CUlt.'S program
instruclions. All con1pu1crs n1us1have a Central Proce~sing Unit.
Following arc some Examples of CPU :-
• Otitput Devices
The data processed into useful infonnarion is
called output. Output devices arc used to display
the result ofprocessing.
