kernel mode

Kernel mode is a powerful, privileged level of a computer's operating system that allows software to access hardware components and system resources directly. Think of it as the control room where the core system (the kernel) manages tasks like memory, input/output devices, and security. Programs running in kernel mode have full access to all parts of the system, enabling efficient and safe operation. However, because it has extensive control, errors in kernel mode can affect the entire system, which is why most applications run in a less privileged mode called user mode.
