This set of Computer Fundamentals Problems focuses on “Parallel Processing Systems”.
1. Execution of several activities at the same time.
a) processing
b) parallel processing
c) serial processing
d) multitasking
View Answer
Explanation: 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
View Answer
Explanation: 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
View Answer
Explanation: 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
View Answer
Explanation: 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
View Answer
Explanation: Bit level parallelism is based on increasing processor word size. It focuses 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
View Answer
Explanation: Instructional level uses micro architectural techniques. It focuses 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
View Answer
Explanation: 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
View Answer
Explanation: 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
View Answer
Explanation: 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
View Answer
Explanation: In parallel processing, the several instructions are executed simultaneously.
