COMPUTER NETWORKING

Detailed explanation-1: -Routers send ‘packets’ of data between computers on different networks. Each data packet contains the IP address of the computer/network that the data is being sent to. The router will use the IP address to work out the best route in which to send the data to it’s destination.

Detailed explanation-2: -Hubs are basic networking devices that operate at the Physical Layer and they are used to send the data packets to all the connected devices, without any filtration. A Switch keeps track of the MAC addresses of all connected devices and hence, it can tell which device or system is plugged into which port.

Detailed explanation-3: -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-4: -It transmits data in the form of electrical signals. A router sends data in the form of a packet and uses the IP address for data transmission. A router is an advanced and intelligent networking device, while a hub is passive and without any intelligence.
