The user has better control over the computer when there is an interruption. Without interrupt, a user may have to wait for a given application to have a higher priority. The process will be dealt with immediately by theCPU.
Interrupt method has better performance than polling method. The chances of data loss are greater in Polling than Interrupt, as the device is continuously checked for readiness.
An interrupt is an event that changes the sequence of instructions. Program errors, page faults, and requests to monitor an event are some of the causes of these interrupt.
Interrupts can be used to stop a running program, service the device, and continue with it. The building blocks of operating systems are interrupted. An interrupt is generated by a counter.
There is a difference between Interrupt andException.
If there is an interrupt present, the handler will stop the current instruction and load the program counter from the location given by the interrupt table.
When a high priority interrupt occurs to the processor, the hardware interrupt can be delayed. The hardware that can’t be delayed should be processed by the processor immediately. There are two types of software interrupt.
There are three types of Interrupts. There is an external interruption.
These types of interrupt are caused by electrical interference or malfunctioning devices.
