Interrupt Descriptor Table is a fundamental component of x86-based systems. It is a memory-resident table that defines how the processor should dispatch all interrupts and exceptions. Each entry specifies the address of an interrupt handler, the segment selector, and gate type and privilege level. The table is loaded by the processor using the lidt instruction and is essential for proper interrupt and exception handling in both protected mode and long mode.
