The Interrupt Vector Table (IVT) is a data structure used by the x86 architecture to manage interrupts. It is a table of pointers to interrupt handlers, which are routines that handle interrupts. The IVT is usually located at the beginning of memory (address 0x0000) and contains 256 entries, each representing a specific interrupt.
The keyword IVTHandleInterrupt often refers to a user-defined function or a specialized handler designed to handle an interrupt vector table (IVT) entry. ivthandleinterrupt
In modern Windows operating systems, IvtHandleInterrupt is a function embedded within the main Windows kernel image, ntkrnlmp.exe . The prefix structurally stands for Interrupt Vector Table , a low-level data structure that maps peripheral hardware interrupts to their corresponding Interrupt Service Routines (ISRs). The Interrupt Vector Table (IVT) is a data

The IVT is a fixed-size table in memory where each entry, or "vector," holds the memory address of a specific — the function that should be executed when a particular interrupt occurs. On startup, the operating system populates this table, linking each interrupt number to its appropriate handler function in the kernel. For example, when a timer interrupt occurs, the CPU automatically looks up the corresponding address in the IVT and jumps to that code.

IVTHandleInterrupt is a UEFI protocol that allows a driver or a firmware component to register an interrupt handler for a specific interrupt. When an interrupt occurs, the UEFI firmware will call the registered interrupt handler to handle the interrupt.
