Interrupt

Detailed explanation-1: -An interrupt is a signal emitted by a device attached to a computer or from a program within the computer. It requires the operating system (OS) to stop and figure out what to do next. An interrupt temporarily stops or terminates a service or a current process.
Detailed explanation-2: -An interrupt is a signal that is sent to the processor to request immediate attention. When the processor receives this request, it suspends what it is doing and runs the process associated with the interrupt.
Detailed explanation-3: -Signals are software generated interrupts that are sent to a process when an event happens. Signals can be synchronously generated by an error in an application, such as SIGFPE and SIGSEGV, but most signals are asynchronous.
Detailed explanation-4: -An internal interrupt is a specific type of interrupt that is caused by instructions embedded in the execution instructions of a program or process.
