Index Ntoskrnl.exe

ntoskrnl.exe (short for Windows NT operating system kernel), also known as kernel image, provides the kernel and executive layers of the Windows NT kernel space, and is responsible for various system services such as hardware virtualization, process and memory management, thus making it a fundamental part of the system.

Architecture of Windows NT

The architecture of Windows NT, a line of operating systems produced and sold by Microsoft, is a layered design that consists of two main components, user mode and kernel mode.

Global Descriptor Table

The Global Descriptor Table (GDT) is a data structure used by Intel x86-family processors starting with the 80286 in order to define the characteristics of the various memory areas used during program execution, including the base address, the size, and access privileges like executability and writability.

Interrupt descriptor table

The Interrupt Descriptor Table (IDT) is a data structure used by the x86 architecture to implement an interrupt vector table.

Interrupt flag

IF (Interrupt Flag) is a system flag bit in the x86 architecture's FLAGS register, which determines whether or not the CPU will handle maskable hardware interrupts.

Physical Address Extension

In computing, Physical Address Extension (PAE), sometimes referred to as Page Address Extension, is a memory management feature for the x86 architecture.

Symmetric multiprocessing

Symmetric multiprocessing (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all processors equally, reserving none for special purposes.

Task state segment

The task state segment (TSS) is a special structure on x86-based computers which holds information about a task.
