switched communications network

Also known as: switched network

Quick Summary

A switched communications network is a system that connects multiple users, enabling data transfer and exchange. It uses a network of switches, or nodes, where each user connects to a node. This is more efficient than direct point-to-point links between every user.12

There are two main types of switching:

  • Circuit Switching: This establishes a dedicated physical path for communication that is held for the duration of the connection. Traditional telephone systems are an example of circuit-switched networks. They offer minimal transmission delays and guarantee a steady bandwidth.324
  • Packet Switching: This technology breaks digital data into small pieces called packets. Each packet travels independently through the network, being temporarily stored and forwarded at intermediate nodes. This method is more efficient and better suited for computer technology, forming the basis of the Internet.32
