The Kernel
Commonly referred to as the 'kernel'
A memory resident, which means it remains inmemory while the computer is running, other parts of the operating system are nonresident, meaning these instructions remain on a storage medium until they are needed.

How is a memory-resident part of an operating system different from a nonresident part of an operating system?

Memory resident instructions are instructions that remain in the memory while the computer is running. Nonresident instructions remain on the storage medium until they are needed.
Resident PROGRAMS are still present in memory of the computer and need not be launched by the operator. Usually their function coincides with the operating system.
It is commonly called "virtual memory".
The central module of an operating system. It is the part of the operating system that loads first, and it remains in main memory. Because it stays in memory, it is important for the kernel to be as small as possible while still providing all the essential services required by other parts of the operating system and applications. Typically, the kernel is responsible for memory management, process and task management, and disk management. The definition of kernel is "the portion of an OS (Operating System) that is responsible for interacting with the hardware. It is the operating system software that runs in kernel mode on the computer's processor and which provides low-level intelligence for the operating system. In other words, the kernel is the "heart" of an operating system.
An Operating System manages resources. Memory is one example of resource management.
Linux is an operating system kernel. It is a portion of the software that makes up a complete operating system.
