Difference between Circut Switched Networks and Packet Switched Networks

Sr. No.	Topic	Circuit Switched Networks	Packet Switched Networks
1	Type of Network	Circuit-switched networks are connection-oriented networks.	Packet-switched networks are connectionless networks.
2	Definition	In this type of network, a dedicated route is established between the source and the destination, and the entire message is transferred through it.	In this type of network, the message is divided and grouped into a number of units called packets that are individually routed from the source to the destination.
3	Flexibility	Routs of the networks are inflexible in nature.	Routs of the networks are flexible in nature.
4	Resource Utilization	Once a route is established between the source and the destination, the route cannot be used by any other user. This leads to poor utilization of resources.	It allows simultaneous usage of the same channel by multiple users. This guarantees better resource utilization.
5	Reliability of Network	Circuit-switched networks are more reliable.	Packet-switched networks are less reliable.
6	Protocol types	It uses relatively simple protocols for delivery.	It uses relatively complex protocols for delivery.
7	Bandwidth Requirement	Bandwidth requirement is high in this type of network even for a low volume of data transmission.	Bandwidth requirement is less in this type of network because bandwidth usage wisely as a number of packets from multiple sources can be transferred via the same link.
8	Installation Cost	Installation cost is low in this type of network.	Installation cost is high in this type of network.
9	OSI Layer Working	It is present at the Physical layer.	It is present at the Network layer.
10	Modes Used	Time division switching and Space division switching.	Virtual circuit switching and datagram switching.
11	Chances of Congestion	Congestion can occur at installation time.	Congestion can occur at every packet level.
12	Delay	It may have a call setup delay.	It may have a Packet transmission delay.
13	Benefits	Dedicated routes ensure steady communication.	Flexible routes avoid network failures and provide better bandwidth coverage.
14	Drawbacks	Dedicated routes not usable for multiple data transmission. Hence, this leads towards the high bandwidth requirement.	Complex network structure and installation costs always remain high.
15	Usability	They are suitable for long continuous transmission, like voice calls.	They are unsuitable for applications that cannot afford delays in communication like high-quality voice calls. Hence, mostly used in data communication.
