Packet switching
A network communication method dividing data into packets routed individually through networks following available paths. Packet switching enables efficient shared network usage versus circuit switching.
Real World
When you stream a song on Spotify, the audio file is split into thousands of small packets that may travel via different routes across the internet. Your device reassembles them in the correct order so the music plays seamlessly.
Exam Focus
Always contrast packet switching with circuit switching — explain how packets take independent routes and are reassembled at the destination.
