The '''Interrupt Descriptor Table''' ('''IDT''') is specific for the <tt>I386</tt> architecture. It is the [[Protected mode]] counterpart to the [[Real Mode]] Interrupt Vector Table ([[IVT]]) telling where the [[Interrupt Service Routines]] (ISR) are located. It is similar to the [[Global Descriptor Table]] in structure.

The IDT entries are called gates. It can contain Interrupt Gates, Task Gates and Trap Gates.
