Differentiate: Circuit Switching and Packet Switching

Differentiate: Circuit Switching and Packet Switching.

Circuit Switching	Packet Switching
Connection oriented	Connectionless
Initially designed for Voice communication	Initially designed for Data Transmission
With circuit switching a dedicated path is established between two stations for communication	With packet switching, a station transmits data in small blocks, called packets
Dedicated path	No Dedicated path
Fixed bandwidth	Dynamic bandwidth
Path is established for entire conversation	Route is established for each packet
Inflexible, because once a path is set all parts of a transmission follows the same path	Flexible, because a route is created for each packet to travel to the destination
Message is received in the order, sent from the source	Packets of a message are received out of order and assembled at the destination
Circuit Switching is implemented at Physical Layer	Packet Switching is implemented at Network Layer
Wastage of resources are more in Circuit Switching	Less wastage of resources as compared to Circuit Switching
It is not a store and forward technique	It is a store and forward technique
Transmission of the data is done by the source	Transmission of the data is done not only by the source, but also by the intermediate routers
In Circuit switching, charge depend on time and distance	In Packet switching, charge is based on the number of bytes and connection time
For EX. PSTN	For EX. GPRS/EDGE
