Detailed explanation-1: -What exactly do routers do? At this point, you can see that routers can connect different types of networks together and send data between them. They can do this because they are intelligent devices and can perform the following functions: They can read data and decide where to send it.

Detailed explanation-2: -Router. Routers help transmit packets to their destinations by charting a path through the sea of interconnected networking devices using different network topologies. Routers are intelligent devices, and they store information about the networks they’re connected to.

Detailed explanation-3: -Answer: A switch is called an intelligent hub because before simply forwarding a packet it checks for the intended destination for the packet and forwards it to that destination only, this is called packet filtering.

Detailed explanation-4: -A bridge is a programmable intelligent device that connects physically separate LAN segments into one logical LAN segment. There are four categories of bridge: transparent, source routing, encapsulating, and translating. Transparent bridges are used for Ethernet, source routing bridges for token ring networks.

Detailed explanation-5: -A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection.
