How does a computer system handle interrupts?
An interrupt is a signal sent by hardware or software to the processor for processing.
The process that runs when an interrupt is generated is the Interrupt Handler.
The CPU saves the state of the ongoing process and shifts its attention to the interrupt generated by giving access to the interrupt handler..
What are interrupts in computer architecture?
An interrupt is a signal from a device attached to a computer or from a program within the computer that requires the operating system to stop and figure out what to do next.Sep 2, 2023.
What is interrupt controller in computer architecture?
The standard interrupt controller sends an interrupt signal to the processor core when an external device requests servicing.
It can be programmed to ignore or mask an individual device or set of devices..
What is interrupt cycle in computer architecture?
Interrupt Cycle:
It is the process by which a computer retrieves a program instruction from its memory, determines what actions the instruction requires, and carries out those actions.
This cycle is repeated continuously by the central processing unit (CPU), from bootupto when the computer is shut down..
What is interrupted IO in computer architecture?
Interrupt driven I/O is an alternative scheme dealing with I/O.
Interrupt I/O is a way of controlling input/output activity whereby a peripheral or terminal that needs to make or receive a data transfer sends a signal.
This will cause a program interrupt to be set..
What is the interrupt cycle in computer system architecture?

It is the process by which a computer retrieves a program instruction from its memory, determines what actions the instruction requires, and carries out those actions..
What is time interrupt in computer architecture?
Timer Interrupts: Generated by a system timer or clock to indicate the expiration of a specified time interval.
Timer interrupts are commonly used for scheduling tasks, measuring time intervals, and triggering periodic events..
- A software interrupt, also called a processor generated interrupt, is generated by the processor executing a specific instruction.
Common processor-generated-interrupts are the divide-by-zero exception and the general-fault or page-fault exception. - Interrupt structure refers to the precedence of interrupts.
Hardware events that cause interrupts are assigned CPU interrupt levels.
The CPU can disable interrupts of a certain level and below, thus allowing an important interrupt to preempt an interrupt of lower priority, but not vice-versa.
