what is packet switching
Packet switching is the method used to relay data over long distances (utilizing the protocols such as Frame Relay, IP and X.25). Packet switching means that the data needed to be transferred is divided into ‘packets’, switches and routers are used to send the data between ‘hops’ , and addresses on the packets denote their ultimate destination.
Packet switching is much more preferable to circuit switching which involves sending data in order, which takes a long time.
The benefits of packet switching include better use of overall network bandwidth by using available routes to send data, also packet switching networks are cheaper to set up.
However on the shorter end of the stick, there are longer delays s data is inaccessible until all packets arrive and are arranged at the destination. Also due to the numerous links used to transfer the packets there are increased chances of security breaches.
