Question # 1:

Five processes A, B, C, D and E are given below with their run time and arrival time.

Process CPU Time Arrival Time

A............. 8 .................. 0

B............... 1 .................. 1

C............... 2 .................. 3

D............... 1 .................. 4

E................ 5 .................. 2

(Where as Quantum = 3 ms)

Find the Turnaround Times, Waiting time and draw the Gantt chart for these processes by

using Shortest Job First and Round Robin scheduling Algorithms.

A computer system has a 32-bit virtual address space with a page size of 4K and 8
bytes per page table entry.

Suppose that the system distinguishes among four types of resources, (A, B, C and D), the following is an example of how those resources could be distributed. There are five processes that take part in the execution and needed resources. You should find the all possible safe sequences for allocating the given resources.

Question 1: Marks: 10

Suppose there are number of processes running on a system. New process in this

system arrives at an average of ten processes per minute. Each process requires an

average of 4 seconds of service time. Estimate the fraction of CPU busy time in a

system with a single processor.

Question # 1:
Read the following program carefully and write the output of the program. Explain each line of code according to given numbering.
