Detailed explanation-1: -To determine the route and destination of a packet, a router examines the IP addresses of packets. A switch looks at the MAC address of each device to transfer data to the correct destination. Routers use data packets, whereas switches, which are part of the data-link layer, typically work with data frames.
Detailed explanation-2: -Connect multiple hosts: Normally, a switch provides a large number of ports for cable connections, allowing for star topology routing. It is usually used to connect multiple PCs to the network. Forwards a message to a specific host: Like a bridge, a switch uses the same forwarding or filtering logic on each port.
Detailed explanation-3: -A network switch forwards data packets between devices. Switches send packets directly to devices, rather than sending them to networks like a router does.
