3.4-11 Packet buffering in Go-Back-N. What are some reasons for discarding received-but-out-of-sequence packets at the receiver in GBN? Indicate one or more of the following statements that are correct. The sender will resend that packet in any case. If some packets are in error, then its likely that other packets are in error as well. The implementation at the receiver is simpler. Discarding an out of sequence packet will really force the sender to retransmit.

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
