Question
Differentiate between packet switching and message switching technique in network communication.
✓
Answer
Packet switching: In packet switching, a fixed size of data packet that can be transmitted across the network is specified and then the data packets are sent through switching stations to the final destinations. All the packets are stored in the main memory instead of disk. As a result accessing time of packets is reduced.
Message switching: The source computer sends data (message) to the switching station, which stores data in a buffer. It then looks for a free link to another switching station and sends data to that station. This process continues until data is delivered to the destination computer. This type of switching technique is also known as “store and forward” switching.
