Problem 1) W congested computer network has a 2% chance of losing a data packet (lost packets must be resent), and a packet losses are independent events. An e-mail message requires 100 packages.

(1) what is the distribution of the number of data packets that must be resent? Please choose one below.

(A) Binomial (B) Geometric (C) Poisson

(2) What is the probability that at least one packet must be resent?

(3) What is the mean of the number of packets that must be resent?

(4) What is the standard deviation of the number of packets that must be resent?

Problem 2) From 500 customers, a major appliance manufacturer randomly selects 5 customers without replacements. The company estimates that 125 of the customers will reply to the survey.

(1) What are the possible values that X takes where X = the number in the same reply tot he survey?

(2) What is the probability that at most one customers in the sample reply tot he survey?

Computer A is sending a packet to Computer B, and the network topology says it must go through Switch A, then a router, the Switch B, and then the packet reaches switch B. I'm trying to describe this process of sending the packet with OSI model. My book says switches are layer 2 and routers are layer 3. If the packet is traveling down the OSI model from application to physical, how does it go through the router before the...

Computer Network 1. Why is the fragmented packet not put back together before reaching the final destination? a) TCP prevents this from happening b) This could cause checksum errors c) The router just wants to dump the packet as fast as possible 2. What is the purpose of the More Fragments flag in the IP header? (Select all that apply) a) When 0, indicates the packet was not fragmented b) When 1, indicates no more fragments c) When 0, indicates...

Consider Mac who has current wealth (M) of $100,000. Mac faces a 5% chance of losing her automobile, which is currently worth $25,000. Suppose her utility function is M1/2. What is the expected value of the car? What is Mac’s expected utility if she does not buy insurance? How much would Marcy be willing to pay to insure this car?

In a Wi-Fi network, data packets are transmitted between a laptop computer and the access point. Since the transmission is wireless, errors can occur that may render the packet useless, so, when received in error, the packet is discarded. As a protection for errors, an acknowledgement is expected, and if the packet is received in error, it is retransmitted, until correctly received. Consider that the probability that a packet is discarded is p=0.6. (a) What is the probability that the...
