Buses transfer data and communication signals within a computer. They allow different components like the CPU, memory, and input/output devices to exchange information. The bus width and clock speed determine how much data can be transferred at once and how quickly. Wider buses and faster clock speeds improve performance by allowing more data to be processed in less time. A computer has several types of buses that connect different internal components like the processor, cache, and expansion ports.

2.  A computer processes and stores data as a
series of electronic bits. These bits transfer
internally within the circuitry of the computer
along the electrical channels.
 Each channel, called a bus, allows the both
inside and attached system unit to
communicate with each other.

3.  Buses are used to transfer bits of input devices
to memory, from memory to processor, from
processor to memory and from memory to
output.
 Buses consist of two parts – Data bus and
address bus.
 Data bus- to transfer actual data
 Address bus- to transfer information about
where the data should reside in the memory.

4.  The size of the bus, known as bus width
determines the number of width the computer
can transmit at one time.
 The larger the number of bits handled by the
bus, the faster the computers transfers data.
 The wider the bus, the fewer the number of
transfer steps required and the faster the
transfer of data.

5.  In conjunction with the bus width, many
computer professionals refer to the computers
word size.
 Word size is the number of bits a compueter
can interprate and execute at a given time.
 Computers with larger word size ca process
more data in the same amount of time than
computers with a smaller word size.

6.  Every bus also have got clock speed.
 Just like the processor, manufacturers state the
clock speed for each busses is in hertz.
 Todays processors have got 1600MHz.
 The higher the bus clock speed, the faster the
transmission of data, which results in
programme running faster

7.  A computer has got 3 main types of busses :
 A system bus, a back side bus and an
expansion bus.
 A system bus, also known as the Front side bus
(FSB) is part of the motherboard and connects
the processor to the cache.
 An expansion bus allows the processor to
communicate with pheripherals
 A backside bus (BSB) connects the processor to
the cache.
