The document discusses the basics of computers including their main components and uses. It describes how computers accept and process data input to generate output. The key components that control and perform operations are the central processing unit, memory unit, input unit, output unit, and arithmetic logic unit. Common input devices include keyboards, mice, and scanners while output devices are monitors, printers, and speakers used to display the results of processing.

6. Main components of computer
 Input Unit : Input is any data
or instructions entered into the
memory of a computer.
 Control Unit : It manages and
coordinates the entire computer
system.
 Arithmetic Logic Unit (ALU): It
consists of circuits that perform
arithmetic as well as logical
operations.

7. Main Components of Computer
 Central Processing Unit (CPU) : It
is Brain of the computer.It
peform data processing
operations.
 Memory Unit : It is amount of
data that can be stored in the
storage unit.
 Output Unit : Output Unit
receives information from the
CPU and which are used to
display output to the user .
