Difference Between Circuit Switching And Packet Switching

Circuit switching and packet switching are the two different methods of switching that are used to connect the multiple communicating devices with one another. The key difference between circuit switching and packet switching is that Packet Switching is connectionless whereas, circuit Switching is connection oriented.

These are the two most common switching methods. We will understand how these both processes affect the transfer of data from sender to receiver differ from one another.

 Circuit Switching VS Packet Switching

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. Packet switching can be used as an alternative to circuit switching. In the packet switched networks, data is sent in discrete units that have variable length.

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 Circuit Switching and Packet Switching differences. If you liked this article and would like to read more download BYJU’S – The Learning App.
