Packet Switching Definition

Packet switching refers to a protocol in which packets are transmitted from one place to another, messages are divided into packets before they sent. Each packet transmitted individually in the network and can follow different paths(routes) to its destination, Then at the receiver end once the all packets of the same message arrive then they compiled to the original one. Modern Wan protocols are TCP/IP, x.25 both of them are based on packet switching technologies. Whereas telephone services are based on circuit-switching network in which a dedicate line is allocated between two parties to establish effective communication. But packet switching network has its advantage to use over circuit switching network because they are robust for data that can withstand some delays in transmission like email and web pages.
