Consider the single-server queue with geometrically distributed inter-arrival times and service times as discussed in class, with a departure rate of = 0.8. Plot the expected delay of a job as a function of the arrival rate ?. You have to run the simulations long enough, for example at least for 108 time slots.

(Hints: use Little's law to calculate the expected delay, but you have to simulate the queue dynamics to get the expected queue length first.) Note: Choose one programming language to do the simulation from C or Java.

Report should include the plot, and simulation code and annotations.
