The Interrupt Vector Table is an array of function pointers. It is a data structure that associates each interrupt that a microprocessor can receive with the address (pointer) of the function (interrupt service routine) that will handle this interrupt.

Here's a step-by-step explanation:

1. An interrupt is a signal sent to the processor that interrupts the current process. It may be generated by a hardware device or a software program.

2. A vector is a pointer to the memory location where the interrupt service routine (ISR) is stored.

3. The Interrupt Vector Table is essentially an array of these vectors. Each entry in the table corresponds to a specific interrupt.

4. When an interrupt is received, the processor saves its execution state, loads the base address of the Interrupt Vector Table, and jumps to the address of the ISR specified by the interrupt vector.

5. The ISR then runs, handling the interrupt. Once it's done, the processor reloads its saved state and continues execution from where it left off.

6. Therefore, the Interrupt Vector Table does not store the core CPU register data. Instead, it stores the addresses of the ISRs. The CPU register data is typically saved in a stack when an interrupt occurs.
