1. In single processor systems, they only have _______ processor.
A. Zero
B. one
C. two
D. multiple
View Answer
Ans : B
Explanation: Most computer systems are single processor systems i.e they only have one processor
2. How many types of multiprocessors?
A. 2
B. 3
C. 4
D. 5
View Answer
Ans : A
Explanation: There are mainly two types of multiprocessors i.e. symmetric and asymmetric multiprocessors
3. Which multiprocessor system contains a master slave relationship?
A. Symmetric Multiprocessors
B. Singleton Multiprocessors
C. Asymmetric Multiprocessors

View Answer
Ans : C
Explanation: Asymmetric multiprocessor system contains a master slave relationship.
4. Which of the following is Disadvantages of Multiprocessor Systems?
A. Multiprocessor systems is quite expensive
B. All the processors in the multiprocessor system share the memory. So a much larger pool of memory is required as compared to single processor systems.
C. more complex and complicated operating system is required in multiprocessor systems.
D. All of the above
View Answer
Ans : D
Explanation: All of the above are some disadvantages of multiprocessor systems.
5. The feature of the multi-microprocessor architecture is
A. task dependent
B. single bus provider for many processors
C. design is for a specific task
D. All of the above
View Answer
Ans : D
Explanation: The main feature of multi-microprocessor is that it is task dependent. If it is designed for a specific task, then it may not be useful for other tasks.
6. The main objective in building the multi-microprocessor is
A. greater throughput
B. enhanced fault tolerance
C. Both A and B
D. None of the above
View Answer
Ans : C
Explanation: Greater throughput and enhanced fault tolerance are the main objectives of the multi-microprocessor system. These systems incorporate a multiplicity of hardware and software, for the purpose

A. authorized data access and data protection
B. unauthorized data access and data protection
C. authorized data access
D. data protection
View Answer
Ans : B
Explanation: A multiprocessor operating system must take care of unauthorized data access and data protection.
8. A common synchronization mechanism used in multiprocessor operating system is
A. Complex
B. Lockstep
C. Clock
D. Locks
View Answer
Ans : D
Explanation: A common synchronization mechanism used in multiprocessor operating system is Lock
9. In a multiprocessor system, if one processor fails, the system will halt
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : B
Explanation: False, In a multiprocessor system, even if one processor fails, the system will not halt.
