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.

Computer A is sending a 100 kByte long file to Computer B via packet-switching over two consecutive 10 Mbps links of 1000 km length each.Assume that the signal propagation speed on both links is 2.5 x 108 m/s.Furthermore, assume that the maximum length of a packet is 1500 bytes and that Computer A fills each packet to the max, if possible. If transmission starts at time t=0, how long (in seconds) does it take until Computer B has received the last bit of the complete file transfer?Assume that the switch between link 1 and 2 is a "store-and-forward" switch. Furthermore, assume that processing and queuing delays are negligible and no other stations are using the links.
Suppose users share a 3 Mbps link. Also suppose each user requires 150 kbps when transmitting, but each user transmits only 10 percent of the time.

For the remainder of this problem, suppose packet switching is used. Find the probability that a given user is transmitting. c. Suppose there are 120 users. Find the probability that at any given time, exactly n users are transmitting simultaneously. (Hint: Use the binomial distribution.) d. Find the probability that there are 21 or more users transmitting simultaneously.
