Interrupts

What factors are considered when an operating system divides processing time between processes? ( select two)

• The number of processors in the system

• When the task was requested

• The color of the computer

• The size of the computer's monitor

Why is the standard method of processing time allocation unsuitable for tasks that require immediate processing?

• It is faster for immediate tasks

• It prevents other processes from running

• It allows the user to type comfortably

• It optimizes processor usage

What is an interrupt in the context of an operating system?

• A request for immediate attention from the processor

• A type of keyboard input

• A method for processing long tasks

• A device driver

What can cause a processor to be interrupted?

• A change in the computer's color scheme

• Completion of a long-running process

• A request for immediate attention from a hardware device

• An increase in the processor's speed

What is the purpose of an interrupt service routine (ISR)?

• To replace the operating system

• To manage long-running processes

• To respond to an interrupt's request

• To provide software updates

In the context of a keypress, what does the ISR do?

• Decides the computer's color

• Polls the keyboard to determine the pressed key

• Updates the processor's clock speed

• Stores the character in the keyboard buffer

How does an interrupt affect the execution of a running program?

• It has no impact on the program

• It stops the program entirely

• It suspends the current program temporarily

• It restarts the computer

What is the sequence of actions that occur when an interrupt is received during program execution? (select two )

• Interrupt is received, and program continues to run

• Program is halted indefinitely

• ISR is executed, and program resumes after the ISR

• All other processes are halted
