                      Mouse

                      Microphone

                      Scanner

            Processing units can also named as Central

Processing Unit. It can be devided into three parts.

·      Control Unit

·      Arithmetic and Logic Unit

·      Memory Registers

Control Unit

All the controlling of the computer is done by thisunit. This controls all  the devices of the computer giving therequired commands when necessary.

Arithmetic Unit

This performs all kind of arithmetical calculation

and logical operations.

             Memory Registers

The memory registers are included in the processing processing unit and it stores the data which are ready to the Central Processing Unit for calculation or processing.

Speed of a Computer

            Speed is also called as clock speed.The unit is hertz (Hz) . Mega hertz(MHz), Gega hertz(GHz) are used to measure speed of modern computers.

1000HZ    =  1kHZ

1000KHz  =  1Mhz

1000MHz  = 1GHz

        The maximum Bits used for calculations or storing at a time is considered to measure the capacity of the Central Processing Unit. This is also called Word Size of the computer.

Storage Devices

          Storage Devices which are used to store data and

information are also called Backing Storageand

 ExtraMemory. Some of those devices are,

·      Hard Disks

·      Compact Disks
