Trampoline (computers)

For people who check facts
Trampolines (sometimes referred to as indirect jump vectorss) are memory locations holding addresses pointing to interrupt service routines, I/O routines, etc. The idea of "bouncing" off a trampoline is to overcome the limitations imposed by a CPU architecture that expects to always find vectors in fixed locations.
