Vectored interrupts:

 Vectored interrupts: 
When interrupt request is activated the microprocessor control logic executes ideal machine cycle. During this cycle, it generates starting address of interrupt service routine. These addresses are fixed for different interrupts. This memory address of interrupt service routine is called as vector location and interrupts which use these vector locations are called as vectored interrupts.
                   E.g. TRAP, RST 7.5, RST 6.5, RST 5.5
