Whats the difference between full and half duplex? The switch received the frame and inspects the destination MAC address, which is the router that was specified. The frame is then sent it to the Physical layer to transmit the bits. This is a useful bit of information to keeping your back pocket because it all of the same steps that were just outlined for computer 1, to construct a allowing networks to use fewer IP addresses overall. Acknowledgments are made through activity flags present in the segment fields. Networks are split up into subnets by subnetting process and are represented using CIDR ID(Class-less Inter-Domain Routing) to represent the networks.Routers use routing tables to find the destination network and send the data-grams to the appropriate routers that has shorter distance to the destination IP.
