INTERUPPTS

What is an interrupt?

• A type of memory storage

• A signal emitted by hardware or software for immediate attention

• A method of data encryption

• A command executed by the processor

Which type of interrupt is generated by a condition during instruction execution?

• Timer Interrupt

• Program Interrupt

• Hardware Failure Interrupt

• I/O Interrupt

What does a timer interrupt allow the operating system to do?

• Perform functions on a regular basis

• Manage memory allocation

• Handle hardware failures

• Execute user programs

What is the purpose of an Interrupt Handler?

• To perform arithmetic operations

• To execute user programs

• To handle interrupts and resume program execution

• To manage memory allocation

What happens when multiple interrupts occur?

• Only one interrupt can be processed at a time

• All interrupts are processed simultaneously

• Interrupts are queued indefinitely

• The processor ignores all interrupts

What is the function of the data bus?

• To provide power to devices

• To store instructions

• To move data among system modules

• To control access to memory

What does the address bus do?

• Controls the timing of operations

• Designates the source or destination of data

• Transmits command signals

• Carries data between devices

What is a key characteristic of a bus in computer architecture?

• It can only transmit one signal at a time

• It is a shared transmission medium

• It is a dedicated pathway for each device

• It requires multiple processors to function

What does the control line 'Memory write' do?

• Causes data to be read from memory

• Synchronizes operations

• Indicates that an interrupt is pending

• Causes data on the bus to be written into memory

What is the role of the Interrupt Service Routine (ISR)?

• To execute user programs

• To handle interrupts and manage their execution

• To perform arithmetic calculations

• To manage memory allocation
