FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Packet switching is the transfer of small pieces of data across various networks. These data chunks or “packets” allow for faster, more efficient data transfer. Often, when a user sends a file across a network, it gets transferred in smaller data packets, not in one piece.

Detailed explanation-2: -Advantages of packet switching over circuit switching: More efficient than circuit switching. Data packets are able to find the destination without the use of a dedicated channel. Reduces lost data packets because packet switching allows for resending of packets.

Detailed explanation-3: -Since all the bandwidth is often used simultaneously, packet switching is more efficient because it doesn’t have to accommodate limited connections that may not be using all that bandwidth.

Detailed explanation-4: -Drawbacks or disadvantages of Packet switching ➨Packet switching network can not be used in applications requiring very little delay and higher quality of service e.g. reliable voice calls. ➨Protocols used in the packet switching are complex and require high initial implementation costs.

Detailed explanation-5: -➨ 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. In packet switching, many packets generated by same node and belonging to the same destination may take different paths.
