+A **network switch** is a device that connects other devices in a [computer network](/wiki/computer_network). It uses [packet switching](/wiki/packet_switching) to forward data frames only to the specific device they are intended for, enhancing network efficiency compared to older [network hubs](/wiki/network_hub). This intelligent routing allows multiple devices to communicate simultaneously.
