Answer:

a. When circuit switching is used, only 1 user can be supported because circuit switching dedicates the entire bandwidth to a single user's connection, so the bandwidth cannot be shared among multiple users.

b. If two or fewer users transmit at the same time, the link capacity is sufficient to handle the transmission rates, and there will be no queuing delay before the link. If three users transmit at the same time, the link capacity of 10 Mbps is exceeded, and a queuing delay will occur because packets will have to wait in a queue before being transmitted.

c. The probability that a given user is transmitting is 0.2 because each user transmits only 20 percent of the time.

d. If there are three users, the probability that all three users are transmitting simultaneously is 0.2 * 0.2 * 0.2 = 0.008. The fraction of time during which the queue grows is equal to the probability that all three users are transmitting simultaneously because that is when the link capacity is exceeded and packets must wait in a queue.

When a network analyst is looking into stolen business data, an ARP poisoning attack is employed to undermine network connectivity.

ARP poisoning is taking advantage of ARP's flaws to tamper with other networked devices' MAC-to-IP mappings. Since authentication mechanisms to validate ARP messages were not a top priority when ARP was first introduced in 1982, security was never a major concern. Any device connected to the network can respond to an ARP request, regardless of who the initial message was meant for. An attacker at Computer C may answer to Computer A's "ask" for Computer B's MAC address, for instance, and Computer A would regard this response as genuine. Many assaults have been made feasible as a result of this carelessness. The ARP cache of other hosts on a local network can be "poisoned" by a threat actor using readily accessible technologies.

Limitation of early networks that used a daisy chain method of connecting computers are:

a. Total number of computers that could be connected

c. Cable length

Total number of computers that could be connected: In a daisy-chain network, each computer is connected to only one other computer, meaning that the total number of computers that could be connected was limited. The chain could only be as long as the last computer in the chain, and adding additional computers meant rewiring the entire network.

Cable length: Another limitation was cable length, as the cable connecting each computer could only be so long. This meant that if computers were far apart, a daisy-chain network could not be used, as the cables would be too short to reach from one computer to another.
