Test: Operating System - 1 - Question 1

What is an operating system?

Detailed Solution for Test: Operating System - 1 - Question 1

An Operating System acts as an intermediary between user/user applications/application programs and hardware. It is a program that manages hardware resources. It provides services to application programs.

In Operating Systems, which of the following is/are CPU scheduling algorithms?

Detailed Solution for Test: Operating System - 1 - Question 2

In Operating Systems, CPU scheduling algorithms are:
i) First Come First Served scheduling
ii) Shortest Job First scheduling
iii) Priority scheduling
iv) Round Robin scheduling
v) Multilevel Queue scheduling
vi) Multilevel Feedback Queue scheduling
All of these scheduling algorithms have their own advantages and disadvantages.

Test: Operating System - 1 - Question 3

Which one of the following errors will be handle by the operating system?

Detailed Solution for Test: Operating System - 1 - Question 3

All the mentioned errors are handled by OS. The OS is continuously monitoring all of its resources. Also, the OS is constantly detecting and correcting errors.

Test: Operating System - 1 - Question 4

If a process fails, most operating system write the error information to a ______

Detailed Solution for Test: Operating System - 1 - Question 4

If a process fails, most operating systems write the error information to a log file. Log file is examined by the debugger, to find out what is the actual cause of that particular problem. Log file is useful for system programmers for correcting errors.

Test: Operating System - 1 - Question 5

What does OS X has?

Detailed Solution for Test: Operating System - 1 - Question 5

OS X has a hybrid kernel. Hybrid kernel is a combination of two different kernels. OS X is developed by Apple and originally it is known as Mac OS X.

Test: Operating System - 1 - Question 6

In a timeshare operating system, when the time slot assigned to a process is completed, the process switches from the current state to?

Detailed Solution for Test: Operating System - 1 - Question 6

In a time-sharing operating system, when the time slot given to a process is completed, the process goes from the running state to the Ready State. In a time-sharing operating system, unit time is defined for sharing CPU, it is called a time quantum or time slice. If a process takes less than 1 time quantum, then the process itself releases the CPU.

Test: Operating System - 1 - Question 7

When a process is in a “Blocked” state waiting for some I/O service. When the service is completed, it goes to the __________

Detailed Solution for Test: Operating System - 1 - Question 7

Suppose that a process is in “Blocked” state waiting for some I/O service. When the service is completed, it goes to the ready state. Process never goes directly to the running state from the waiting state. Only processes which are in ready state go to the running state whenever CPU allocated by operating system.

Test: Operating System - 1 - Question 8

The FCFS algorithm is particularly troublesome for ____________

Detailed Solution for Test: Operating System - 1 - Question 8

In a time sharing system, each user needs to get a share of the CPU at regular intervals.

Test: Operating System - 1 - Question 9

For an effective operating system, when to check for deadlock?

Detailed Solution for Test: Operating System - 1 - Question 9

In an effective operating system, we must verify the deadlock each time a request for resources is made at fixed time intervals.

Test: Operating System - 1 - Question 10

For real time operating systems, interrupt latency should be ____________

Detailed Solution for Test: Operating System - 1 - Question 10

Interrupt latency is the time duration between the generation of interrupt and execution of its service.
