network switches
What is network switches?
Network switches are networking devices that operate at the data link layer (Layer 2) of the OSI model. They connect multiple devices within a network (e.g., computers, servers, printers) by forwarding data packets between them. Unlike hubs that broadcast data to all connected devices, switches learn the MAC addresses of connected devices and forward data only to the intended recipient, increasing network efficiency and reducing collisions. They are commonly used in home networks, small office networks, and large enterprise networks to facilitate communication and resource sharing.
