What (who) is vectored interrupt - definition


Vectored interrupt         
PROCESSING TECHNIQUE IN COMPUTER SCIENCE
Vectored Interrupt
In computer science, a vectored interrupt is a processing technique in which the interrupting device directs the processor to the appropriate interrupt service routine. This is in contrast to a polled interrupt system, in which a single interrupt service routine must determine the source of the interrupt by checking all potential interrupt sources, a slow and relatively laborious process.

DATA STRUCTURE

Interrupt service routine; Interrupt routines; Interrupt Handler; Interrupt Service Routine; FLIH; SLIH
In computer systems programming, an interrupt handler, also known as an interrupt service routine or ISR, is a special block of code associated with a specific interrupt condition. Interrupt handlers are initiated by hardware interrupts, software interrupt instructions, or software exceptions, and are used for implementing device drivers or transitions between protected modes of operation, such as system calls.
