CSCI 114 (01): Quiz3

Given N, the number of tasks that are either waiting in the queue or being processed by the CPU, arrival rate Y, and response time R, what is the relationship between N, Y, R in a stable system?

• N = YR

• N = Y/R

• N = Y+R

• N = YR^2

Given 60 % utilization, the ratio of response time R and execution time S is:

• 2.5

• 1.25

• 1.33

• 1.67

Given three tasks A, B, C with service time of 6ms, 4ms, and 4ms, respectively. Assume that all three tasks arrive all at the same time but A comes slightly before B and B comes slightly before C. Please show the detailed schedule for the following algorithms:
