(1) Round robin scheduling is essentially the preemptive version of 1 FIFO 2 Shortest job first 3 Shortest remaining 4 Longest time first (2) A page fault occurs 1 when the page is not in the memory 2 when the page is in the memory 3 when the process enters the blocked state 4 when the process is in the ready state (3) Which of the following will determine your choice of systems software for your computer? 1 Is the applications software you want to use compatible with it? 2 Is it expensive? 3 Is it compatible with your hardware ? 4 Both 1 and 3 (4) What is a shell? 1 It is a hardware component 2 It is a command interpreter 3 It is a part in compiler 4 It is a tool in CPU scheduling ose the answer from the candidate 1, 2, 3, and 4. (5) In the blocked state 1 the processes waiting for I/O are found 2 the process which is running is found 3 the processes waiting for the processor are found 4 none of the above (6) Virtual memory is 1 An extremely large main memory 2 An extremely large secondary memory 3 An illusion of extremely large main memory 4 A type of memory used in super computers. (7) The process related to process control, file management, device management, information about system and communication that is requested by any higher level language can be performed by 1 Editors 2 Compilers 3 System Call 4 Caching (8) Multiprogramming systems. 1 Are easier to develop than single programming systems 2 Execute each job faster 3 Execute more jobs concurrently 4 Are used only on large main frame computers (9) Which is not the state of the process? 1 Blocked 2 Running 3 Ready 4 Privileged 1 (10) The solution to Critical Section Problem is Mutual Exclusion. 1 The statement is false 2 The statement is true. 3 The statement is contradictory. 4 None of the above (11) The state of a process after it encounters I/O instruction is 1 Ready 2 Blocked/Waiting 3 Idle 4 Running
