Definition: Packet switching is a communications protocol technology that breaks down data into small packets in order to make this data easier to send over computer networks, specifically, on the Internet. These packets - tiny pieces of data - are transmitted over different networks until they reach their original destination and are reassembled into their original format.
Packet switching protocols are an important part of the Web, since this technology makes it possible to transmit high quality data online anywhere in the world, quickly.
