Question

T/F about operating system, thank you very much

1. A compiler belongs to an application programming interface.

2. An OS is distinguished from other system software in that it runs faster because it has exclusive control of the processor.

3. One advantage of resource abstraction is that it provides the most efficient use of resources.

4. Use of metered automobile parking space is an example of time-multiplexed sharing.

5. Space-multiplexed sharing is related to swapping processes to and from disks.

Answer 1

1. A compiler belongs to an application programming interface.

True,

• Application Programming Interface (API) is an interface used by the software component to communicate with system/application.
• A compiler is a program used to process instructions written in a programing language to machine code which can be understood by the processor, in that way we can say compiler is an API.
• Java compiler API is an example

2. An OS is distinguished from other system software in that it runs faster because it has exclusive control of the processor.

True,

• System software act like an interface between hardware and application programs
• Examples are Operating systems and device drivers
• The OS's most trusted service is Kernal mode which provides exclusive access and hence runs faster.

3. One advantage of resource abstraction is that it provides the most efficient use of resources.

False,

• Resource abstraction makes the use of resources easier by the application programmer without bothering about how the hardware works.
• For efficient use of resources, we need to use resource allocation method efficiently.

4. Use of metered automobile parking space is an example of time-multiplexed sharing.

True,

• in a metered automobile parking space each car has exclusive control over the space for the given amount of time so it is not dividing the resource into a unit so hence it is an example of time multiplexed sharing.

5. Space-multiplexed sharing is related to swapping processes to and from disks.

True,

• In space multiplexed sharing a resource is divided into units and each of them is allocated to processes
• Disk and main memory are examples for space multiplexed sharing
