1. Switches are essential networking devices. They connect multiple devices within a local area network (LAN), allowing for seamless communication between them. 2. They operate at the data link layer of the OSI model, forwarding data packets based on MAC addresses. This enables efficient and targeted data transfer. 3. Switches come in various types, such as managed and unmanaged switches. Managed switches more advanced features like VLAN configuration and port security. 4. They can enhance network performance by reducing collisions and providing dedicated bandwidth for each connected device. This ensures smooth data flow even in busy networks. 5. Switches play a crucial role in building reliable and scalable networks, facilitating the growth and expansion of business operations and digital s.
