Consider an unreliable communication channel that can successfully send a message with probability 1/2, or otherwise, the message is lost with probability 1/2. How many times do we need to transmit the message over this unreliable channel so that with probability 63/64 the message is received at least once?

Explain your answer. Hint: treat this as a Bernoulli process with a probability of success 1/2. The question is equivalent to: how many times do you have to try until you get at least one success?

    A data packet is transmitted over a lossy wireless channel with packet error rate 0.3. Most communication systems adopt the Automatic Repeat reQuest (ARQ) protocol. That is, if a packet is successfully (with probability 0.7) or unsuccessfully (with probability 0.3) received, the receiver respectively sends a one-bit ‘ACK’ or ‘NAK’ message (over a separate feedback channel) to the transmitter. After receiving an ‘ACK’, the transmitter will move on to the next packet transmission; otherwise, the transmitter will re-transmit the same...

    In the last module you learned a formula for calculating bit rate, R = b/t, that is the number of bits divided by the time. This formula expresses the number of bits that are transmitted over a circuit in a given period of time. In practice, however, we are not only concerned with the number bits transmitted, but also with the number of data bits transmitted over a circuit. The data bits are those that the sender decides to send...

    JAVA MASTERMIND The computer will randomly select a four-character mastercode. Each character represents the first letter of a color from the valid color set. Our valid color choices will be: (R)ed, (G)reen, (B)lue and (Y)ellow. Any four-character combination from the valid color set could become the mastercode. For example, a valid mastercode might be: RGBB or YYYR. The game begins with the computer randomly selecting a mastercode. The user is then given up to 6 tries to guess the mastercode....
