A network switch is a networking device that connects devices together on a computer network by using packet switching to forward data to its destination. It operates at the data link layer (layer 2) of the OSI model and allows for multiple devices on a network to communicate with each other, eliminating the need for a hub. Switches learn the addresses of connected devices and use this information to optimize communication and reduce network traffic.
