Switches and Hubs
Switches and Hubs represent networking devices used to connect multiple devices in a local area network (LAN). Hubs operate at the physical layer of the OSI model, allowing devices to communicate with each other by forwarding data packets to all connected devices. On the other hand, Switches operate at the data link layer, ensuring efficient data transmission by forwarding packets only to the intended recipient. Switches and Hubs play a crucial role in creating a reliable and secure network infrastructure, improving overall network performance and speed. These devices are essential in managing network traffic, enhancing connectivity, and facilitating seamless communication between devices.
