BCS303-3

A program under execution is called:

• Instruction

• Thread

• Process

• Procedure

Which of the following is required by a process for its execution?

• CPU time

• Memory

• Files and I/O devices

• All of the above

Resources are given to a process:

• Only after it terminates

• When it is created or at run time

• Only when it is idle

• When it is stored on disk

What happens to resources when a process terminates?

• They are permanently deleted

• The operating system reclaims them

• They are locked forever

• They are automatically transferred to another process

A program stored on disk is considered as:

• Active entity

• Passive entity

• Running entity

• Resource entity

The program under execution is considered as:

• Passive entity

• Static entity

• Active entity

• Dormant entity

Which of the following is NOT a resource needed by a process?

• CPU time

• Memory

• Operating system kernel

• I/O devices

The distinction between program and process is that:

• Program is an active entity, process is passive

• Program is passive, process is active

• Both program and process are passive

• Both program and process are active

Which system component is responsible for reclaiming resources after process termination?

• File manager

• CPU scheduler

• Operating system

• Compiler

Which of the following best describes a process?

• A static set of instructions

• A program in execution with allocated resources

• A passive file stored on disk

• A hardware component
