Computer Fundamentals Problems on “Parallel Processing Systems”.
1. Execution of several activities at the same time.
a) processing
b) parallel processing
c) serial processing
d) multitasking
Answer: b
Clarification: Execution of several activities at the same time is referred to as parallel processing. Like, Two multiplications at the same time on 2 different processes.
2. Parallel processing has single execution flow.
a) True
b) False
Answer: b
Clarification: The statement is false. Sequential programming specifically has single execution flow.
3. A term for simultaneous access to a resource, physical or logical.
a) Multiprogramming
b) Multitasking
c) Threads
d) Concurrency
Answer: d
Clarification: Concurrency is the term used for the same. When several things are accessed simultaneously, the job is said to be concurrent.
4. ______________ leads to concurrency.
a) Serialization
b) Parallelism
c) Serial processing
d) Distribution
Answer: b
Clarification: Parallelism leads naturally to Concurrency. For example, Several processes trying to print a file on a single printer.
5. A parallelism based on increasing processor word size.
a) Increasing
b) Count based
c) Bit based
d) Bit level
Answer: d
Clarification: Bit level parallelism is based on increasing processor word size. It on hardware capabilities for structuring.
6. A type of parallelism that uses micro architectural techniques.
a) instructional
b) bit level
c) bit based
d) increasing
Answer: a
Clarification: Instructional level uses micro architectural techniques. It on program instructions for structuring.
7. MIPS stands for?
a) Mandatory Instructions/sec
b) Millions of Instructions/sec
c) Most of Instructions/sec
d) Many Instructions / sec
Answer: b
Clarification: MIPS stands for Millions of Instructions/sec. MIPS is a way to measure the cost of computing.
8. The measure of the “effort” needed to maintain efficiency while adding processors.
a) Maintainablity
b) Efficiency
c) Scalabilty
d) Effectiveness
Answer: c
Clarification: The measure of the “effort” needed to maintain efficiency while adding processors is called as scalabilty.
9. The rate at which the problem size need to be increased to maintain efficiency.
a) Isoeffciency
b) Efficiency
c) Scalabilty
d) Effectiveness
Answer: a
Clarification: Isoefficiency is the rate at which the problem size need to be increased to maintain efficiency.
10. Several instructions execution simultaneously in ________________
a) processing
b) parallel processing
c) serial processing
d) multitasking
Answer: b
Clarification: In parallel processing, the several instructions are executed simultaneously.
