Which of the following is a real-time system?

  1. Railway reservation system

  2. Process control system

  3. Payroll processing system

  4. Student information system

  5. Management information system


Correct Option: B
Explanation:

It has to complete within the alloted time.

Which CPU scheduling algorithm is probably the most optimal in terms of turnaround/response time?

  1. FCFS

  2. Shortest Job First

  3. Priority based scheduling

  4. Round-robin scheduling


Correct Option: B
Explanation:

This is probably the most optimal in terms of turnaround/response time. When a job comes in, it inserts it in the ready queue based on its length. When the current process is done, picks the one at the head of the queue and runs it.

Which of the following CPU scheduling algorithms would a time-sharing system likely use?

  1. FCFS scheduling

  2. Priority based CPU scheduling

  3. Round robin scheduling

  4. Shortest Job First


Correct Option: C
Explanation:

This option is correct as starvation can never occur because no priority is given. Order of time unit allocation is based upon process arrival time, similar to FCFS.

The collection of independent computers that appear to the user of the system as single computer is called

  1. centralized system

  2. distributed system

  3. autonomous system

  4. none of these


Correct Option: B

Which type of operating system can be used for building embedded systems and for robotics?

  1. Real-time operating system

  2. Time-sharing operating system

  3. Clustered operating system

  4. Multiprogramming operating system


Correct Option: A
Explanation:

This option is correct because in real-time operating system, there is a fixed time constraint upto which the system has to complete its computing. If the system fails to complete its computing within that time limit, the system will crash.

What is the advantage of distributed system over PC?

  1. Data sharing

  2. Device sharing

  3. Communication

  4. Flexibility


Correct Option: A

Multi-computers are

  1. tightly-coupled

  2. loosely-coupled

  3. closely-coupled

  4. none of the above


Correct Option: A

The distributed systems, which have incremental growth and extensibility are called

  1. closed DS

  2. open DS

  3. coupled DS

  4. none of these


Correct Option: A

Distributed system is

  1. non flexible

  2. more flexible

  3. less flexible

  4. none of these


Correct Option: B

MIPS stands for

  1. Millie Instructions Per Second

  2. Million Instructions Per Second

  3. Mega Instructions Per Second

  4. None of these


Correct Option: B

Fault tolerance capability means

  1. run the task even machine failed in the N/W

  2. stop the task when machine failed in the N/W

  3. wait for repair

  4. none of these


Correct Option: A

In which transparencies, the user cannot recognise whether a resource is remote or local?

  1. Location

  2. Access

  3. Failure

  4. None of these


Correct Option: A

The systems which are designed to allow many users to work together are called

  1. parallel systems

  2. distribute systems

  3. linear systems

  4. none of these


Correct Option: B

The expanding of scale without disrupting the activities of user is called

  1. scaling

  2. naming

  3. linking

  4. none of these


Correct Option: A

RPC stands for

  1. Remote Procedure Call

  2. Random Procedure Call

  3. Random Protocol Connection

  4. None of these


Correct Option: A
