A mechanism or technology used in Ethernet by which two connected devices choose common transmission parameters such as speed, duplex mode and flow control is calledQ15.
What is the minimum number of resources required to ensure that deadlock will never occur, if there are currently three processes P_{1},P_{2} and P_{3} running in a system whose maximum demand for the resources of same type are 3, 4, and 5 respectively.Q16.
There are 200 tracks on a disc platter and the pending requests have come in the order - 36, 69, 167, 76, 42, 51, 126, 12 and 199. Assume the arm is located at the 100th track and moving towards track 200. If sequence of disc access is 126, 167, 199, 12, 36, 42, 51, 69 and 76 then which disc access scheduling policy is used?Q17.
Consider the logic circuit given below.The inverter, AND and OR gates have delays of 6, 10 and 11 nanoseconds respectively. Assuming that wire delays are negligible, what is the duration of glitch for Q before it becomes stable?
