The following uses of computer bus are:
(i) Computer bus are used to send and receive data from secondary storage
(ii)Computer buses are used to connect various component that are the parts of computer.
Capacity of a bus:
The capacity of computer bus depends on the number of data lines in it.The amount of data that
a bus can carry at one time is called Bus width
Meaning of higher bus mean:
Ahigher bus width mean that the bus can carry more data .It increase the performance of
of the computer.
-------->> A bus with 32 lines can carry 32 bits or 4 bytes a time
------->> Abus with 64 lines can carry 64 bits or 8 bytes at a time
