Find the average buffer occupancy, in messages, at the outgoing link of a concentrator for the following case (assume the infinite buffer, M/M/1 model is valid) : 10 terminals, each generating on the average of one message every 4 sec, are statistically multiplexed at the concentrator. The messages are 40 bits long, on the average. The capacity of the outgoing link is C = 1000 bps.

Consider the problem of servo control using PWM signals. Assume we have the following requirements or given conditions. • The repetition period of the PWM pulse for servo control is 20 ms. • The pulse width is between 1.0 to 2.0 ms, with 1.5 ms setting the servos to the center. • We need a resolution of no less than 1 us (micro second) for the pulse width change. • The timer used for the PWM generation has a 16-bit prescaler and a 16- bit counter. • The clock to the prescaler is 10 MHz. Determine the following (which may not be unique): 1. The range of PSC that satisfies the requirements for resolution and period of the pulses.

In a slotted Aloha network with G = 1/2, how is the throughput affected in each of the following cases? a. G is increased to 1. b. G is decreased to 1/4.

True/False: There exists a mapping reduction from ATM to ETM.

Which of the following reasons is true with respect to the statement of "The maximum throughput performance of slotted-ALOHA is about twice that of simple/pure-ALOHA"? because transmission can start only at the beginning of frames time periods in slotted ALOHA because collision detection is implemented (so transmitters stop transmitting if they find a collision) in slotted ALOHA because the performance of slotted-ALOHA is not exactly twice that of simple ALOHA because slotted ALOHA stations can send their packets synchronously.

Compute the capacity and input distribution attaining it for the discrete memoryless channel X → Y with X = y = {0, 1, 2, 3} given by Y = X + Z mod 4, where Z takes on values from Z = {0, 1, 2, 3} with z(0) = 1/2, z(1) = 0, and z(2) = z(3) = 1/4.

1) Given an O/S with soft timers using a single clock, consider a situation where the event list looks like this:   Current time = 4105; Next Signal = 6; Clk Header → 6 → 1 → 3 → 12 → 5 a. What will current time be when the “12” signal is dispatched =  b. At time 4113 a new signal arrives to be scheduled for 4125, fill in the following to reflect this signal being added at that time:        Current time = ; Next Signal = ; Clk Header → 2)  Given a disk with 100 tracks, Consider the following disk request sequence (track numbers): 45, 20, 90, 10, 50, 60, 80, 25, 70. The initial position of the R/W head is on track 50. Determine the distance that will be traversed by the R/W head when the Shortest Seek Time First (SSTF) algorithm is used and the Elevator algorithm (note -the Elevator algorithm will move towards 100 when it starts execution).  Which algorithm will move the fewest tracks , SSTF or Elevator: , and by how many fewer tracks: tracks less than the other algorithm.

e) In a wireless LAN, multiple stations are present, and each station is allocated with different Inter-frame space (IFS) time frames. Assume that station X is assigned with IFS 3 milliseconds, station Y is assigned with IFS 5 milliseconds and station Z is assigned with IFS 4 milliseconds. Which station has the lowest priority? Justify your answer.
