Quick Summary

A router is a device that directs data packets across electronic communication networks, such as the internet. This process is part of packet switching, a technology where data is broken into smaller blocks, or packets, for efficient transmission and reassembly. This method is faster and more effective than older circuit-switched networks. Routers are essential for managing the flow of information and ensuring that data reaches its intended destination on the network.123
