Routers
The network layer (also called layer3) manages device addressing tracks the location of devices on the network and determines the best way to move data. Which means that the network layer must transport traffic between devices that aren't locally attached. Routers are specified at the network layer and provide the routing service switch an internetwork.
It happens like this first when a packet is received on a router interface the destination IP address is checked. If the packet is not destined for that particular router. It will look up the destination network address in the routing table. Once the router chosen an exit interface the packet will be sent to that interface to be framed and sent out on the local network. If the router cannot find an entry for the packets destination network in the routing table the packets destination network in the routing table the router drops the packets.
What is use of Carrier sense multiple access Carrier sense multiple access with collision detection (CSMA/CD) is a form of medium access control in which a station listens to
Take the maximum packet lifetime, T. It's stated that T must be big enough to make sure the packet and its ACK have vanished. Why do we have to have the ACK?
