Network Switches are devices used in computer networks to facilitate communication between different nodes, including computers, servers, and other networked devices. They operate at the data link layer (Layer 2) of the OSI model, allowing them to receive, process, and forward data packets between devices on the same network segment. Network switches use hardware-based switching technology to achieve faster data transfer rates compared to software-based routers. They can also support advanced features such as virtual LANs (VLANs), Quality of Service (QoS), and port mirroring, making them essential for building robust and secure network infrastructures. Network switches are a critical component of modern networking and play a vital role in enabling high-speed, low-latency communication between devices on a local area network (LAN).
