differentiate between packet switching and message switching
Answers
Explanation:
In packet switching message is divided into smaller packets amd each packet is appended with header before transmission. Message switching has higher reliability and lower complexity. As in message switching, one single datagram is either received or lost. One single network path is used for the same.
Explanation:
Message Switching Packet Switching
A complete message is passed across a network. Message is broken into smaller units known as Packets.
In this, computer language used is ASCII, baudot, morse. In packet switching, binary type is used.
In message switching there is no limit on block size. Packet switching places a tight upper limit on block size.
Message exist only in one location in the network. Parts i.e. packets of the message exist in many places in the network.
Example: Hop-by-hop Telex forwarding and UUCP(UNIX-to-UNIX Copy Protocol) Example: Frame Relay, IP, and X. 25
Physical links are allocated dynamically. Virtual links are made simultaneously.
Access time is reduced due to increase in performance as packets are stored in disk. Packets are stored in main memory
