We have a 4 km down CSMA / CD channel with a capacity of 10 Mbps. Assume the average negotiable interval is 2 ∗ ∆ size,  and that the propagation rate is 2 ∗ 10^8 m/s, the length of frames is 50B. By how much is it necessary to increase the minimum size of frames if we want to achieve at least 90% efficiency? Write down all the necessary assumptions.

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.
