Computer network


#1

Assume 100 nodes are connected to a 10000 meter length of coaxial cable. Using some protocol, each node can transmit 100 frames / seconds, where the average frame length is 2500 bits. The transmission rate of the system is 108 bps. The efficiency of the protocol in percentage is _______.


#2

Each node transmits 100 frames/ sec = 100 *2500 bits / sec

100 Nodes will be 2500100100

So efficiency will be 25*106 / 108 * 100 = 25%
