COMPUTER NETWORKING

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: -Packet switching is a method of data transmission whereby the data is divided in packets. Each packet is given a header containing information of the destination. Each packet is forwarded separately over the network via the most optimum route to the destination using the header information.

Detailed explanation-3: -In data communications networks, packet segmentation is the process of dividing a data packet into smaller units for transmission over the network. Packet segmentation happens at layer four of the OSI model; the transport layer.
