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.

What is the packet switching process?

Packet switching is a networking communication method used in telecommunications systems, whereby data is grouped into blocks called packets and routed through a network using a destination address contained within each packet. ... It also means that each packet can take a different route to its destination.

Where do we use packet switching?

Packet switching is used to optimize the use of the channel capacity available in digital telecommunication networks, such as computer networks, and minimize the transmission latency (the time it takes for data to pass across the network), and to increase robustness of communication.
