Self doubt
Identify the incorrect statement : 1. If there are no cycles in resource allocation graph then there is no deadlock. 2. If there is only one instance per resource type and resource allocation graph has a cycle then there is a deadlock. 3. If there is more than ... for some resource type and resource allocation graph has a cycle , there may or may not be a deadlock. 4. All of these

MadeEasy Workbook: Computer Networks - Stop And Wait
The distance from earth to a distant planet is approximately 9*(10^10) m. What is the channel utilization if a stop-and-wait protocol is used for frame transmission on a 64Mbps point-to-point link? Assume that the frame size is 32KB and the speed of light is 3*(10^8) m/s.

MadeEasy Workbook: Computer Networks - Sliding Window
Compute the fraction of the bandwidth that is wasted on overhead(headers and retransmissions) for selective repeat on a heavily loaded 50-kbps satellite channel with data frames consisting of 40 header and 3960 data bits. Assume that the ... data frames is 1% and the error rate for NAK frames is negligible. The sequence numbers are 8 bits.
