    Ethernet Design Cable Length

    In designing Ethernet, we must make sure that the length of cable in the LAN is shorter than the length of the shortest possible message that can be sent. Otherwise, a collision could go undetected. a. Let's assume that the smallest possible message is 64 bytes (including the 33 byte overhead). If we use 10BaseT, how long (in

    Introduction: In Many development organizations and universities network managers must oversee a network that has many computers connected to it that are used by developers for design and product development purposes. Often, these developers are using systems or settings for which the network managers have little or no exper

    Authentication protocol is modeled.

    Suppose we are using a three-message mutual authentication protocol, and Alice initiates contact with Bob. Suppose we wish Bob to be a stateless server, and therefore it is inconvenient to require him to remember the challenge he sent to Alice. Let's modify the exchange so that Alice sends the challenge back to Bob, along with t

    Ethernet Capture Effect

    The teacher went over the following problem in class. However, I do not understand how he explains the work. He skips too many steps and jumps around. I have the final answer but I need a clear and complete explanation on how this problem is solved: Let A and B be two stations attempting to transmit on an Ethernet. Each has a

    Signal to Noise Ratio

    In data communication we often use the term "bandwidth" when we refer to the capacity (bits-per-second) of a link. Strictly speaking, however, bandwidth refers to the range of frequencies (highest frequency minus lowest frequency) that can be carried on a link. Using the frequency definition of bandwidth, what must the bandwidth

    Ethernet Problems

    An Ethernet (this is a simplex network - not a full duplex network) operating at 10 Mbps was observed for 10 minutes. During that period, 150 million bytes were transmitted on the local area network; 120 million bytes were original data bytes and 30 million bytes were overhead and control bytes. (a) What was the channel util
