Network Switches

Network Switches

Network switches are fundamental networking devices used to connect and manage data traffic within local area networks (LANs). They operate at the data link layer (Layer 2) of the OSI model and are essential for efficient data transmission. Switches function by forwarding data packets to their intended destinations based on the device's unique MAC address.

This makes them superior to hubs, which broadcast data to all devices in a network. Network switches provide higher bandwidth, reduced collision rates, and improved network performance. They come in various sizes, from small office switches to large enterprise-grade models, and play a critical role in modern networking infrastructure.
