welcome to learn computer science
online.com and in this video we are
going to discuss what is a computer bus
a computer system is a digital
electronic device that can be programmed
to perform various operations as per the
user requirements the computer system
consists of both hardware components and
software components these hardware
components can be connected either
internally or externally to the computer
system a computer system consists of
number of hardware components some
components are internal to the system
these internal components are mounted
inside the computer casing the internal
hardware components include central
processing unit CPU main memory RM hard
disk graphics card and computer
motherboard when we switch on our
computer these components communicate
with each other in terms of sharing the
data signals program instructions power
and other information necessary for
system to function the computer system
hardware components consist of both
electronic components and as well as
some mechanical components all these
hardware components are connected to the
system with a network of wires that runs
across the computer system the computer
hardware components are physically
interconnected and communicate with each
other through the network of wires that
runs across the computer system in
computer architecture the network of
electrical wires that connects the
various hardware components I referred
as computer buses the computer bus is
our essential component of every
computer system the computer system
performance depends upon the size and
the speed of the computer buses in other
words the computer buses are electrical
wires used to interconnect various
electronic components within a computer
system each computer bus internally
might consist of group of wires tied
together the number of wires present in
a bus could be eight wires sixteen wires
thirty-two wires or sixty-four wires the
size of a bus is measured in terms of
its bus with which indicates number of
wires present in a bus the computer bus
with 64 wires is called a 64-bit bus the
computer system makes use of different
sizes of buses depending upon the system
architecture this network of different
types buses used in the computer is
called a bus system the bus width is an
important performance parameter because
it determines how much data in terms of
bits can be transmitted at one time the
largest system bus width more data will
be transferred which significantly
improves the microprocessor performance
let us now consider one example a 64-bit
computer bus has 64 parallel cables and
therefore it can transmit 64 bits of
data at a time let us now summarize the
computer buses electrical wire
connection used in a computer system
which allows communication between the
various hardware components the computer

buses the computer bus is used in the
computer system can be in the form of
electrical wires different types cables
used in different sizes and the bus is
present on the motherboard the computer
motherboard has an intricate network of
different buses present on the rear side
of the motherboard printed circuit board
