You are using a Selective Repeat protocol with the sequence space being 4 bits. You have also determined that the sender window should be of size 6. What is the best size to use for the receiver window?

The signal to noise ratio of a 3 kHz channel is 15. The maximum bit rate that could be supported is:

In the 802.11 CSMA/CA protocol several Interframe intervals are defined. The following is typically the shortest:

Consider a Go-Back-N protocol with a sender window size of 4, a sequence number range of 32 and a message of 100 packets that needs to be sent. Suppose that the sender at some point in time has a window of packets with sequence numbers 6, 7, 8, and 9 and gets an ack labeled 8. Then the sender should:

If the Hamming distance of a code is 8, the maximum number of errors that can be corrected and detected is, respectively:

The strategy used in non-persistent CSMA is:

Suppose a loaded dice has a probability of throwing a 1 or a 6 to be ¼ each. Suppose the probabilities of the other 4 numbers are equal to each other. Suppose two such loaded dice are thrown. What is the probability of getting a sum of 4?

A 4 kHz signal is properly sampled and quantized with a resulting bit rate of 64 kbps. What is the number of bits of quantization?
