There is a mathematical theory called queuing theory that studies ways in which computer jobs are fed in CPUs and researches on how these can be reduced to a minimum. Show how can a computer estimate the average number of jobs waiting at a queue?
Suppose that in a 5 sec interval jobs arrive as indicated in the following table (Arrival time is assumed to be at the beginning of each second) In the first second jobs A and B arrive. During the second second B moves to the head of the line (A job is completed as it took 1 sec to be served), and C and D jobs arrive and so on.
a. The mean number of jobs in line
b. The mode of the number of jobs in line
Time in seconds Jobs
1 A, B
2 C, D
4 E, F
