Difference Between Circuit Switching And Packet Switching

One of the key differences between Circuit Switching and Packet Switching is in understanding how these both processes that affect the transfer of data from sender to receiver differ from one another. Circuit switching is referred to as the technology of data transfer that utilises sending messages from one point to another. This involves sending messages from the receiver to the sender and back simultaneously. A physical connection gets established during this process along with the receiver; a dedicated circuit is always present to handle data transmissions, through which data is sent.

Circuit Switching

Packet Switching

A single connection which also leads to a single path for establishing a connection between 2 points.

A packet is simply data that has been divided into smaller units along with a header, for ease of transfer containing signal information.

A circuit needs to be established to make sure that data transmission takes place.

Each packet containing the information that needs to be processed, goes through the dynamic route.

A uniform path is followed throughout the session.

There is no uniform path that is followed end to end through the session.

It is most ideal for voice communication, while also keeping the delay uniform.

It is used mainly for data transmission as the delay is not uniform.

Without a connection it cannot exist, as the connection needs to be present on a physical layer.

A connection is not necessary, as it can exist without one too. It needs to be present on a network layer.

Thus, this explains the difference between Circuit switching and Packet Switching. If you liked this article and would like to read more download the Byju’s app today! You may also want to check out the related articles for further reading:

Practise This Question

A famous relation in physics relates moving mass m to the rest mass m0 of a particle in terms of its

speed v and the speed of light c. (This relation first arose as a consequence of special theory of relatively

given by Albert Einstein). A boy recalls the relation almost correctly but forgets where to put the constant 

c. He writes m=m0(1v2)12. Guess where to put the missing c?
