One of the most difficult issues in computer science is the kernel of an operating system (OS). The operating system's kernel is the most critical component. It is the fundamental interface between a computer's hardware and its operations. The kernel links these two so that resources can be adjusted as efficiently as feasible.
It's called a kernel because it works inside the operating system, similar to how a seed works inside a hard shell. Its location in an operating system is depicted in the diagram below. It manages all of the hardware's essential tasks, whether it's a tablet, desktop, server, or any other device.

Process and memory management, disc storage, and low-level networking are all tasks performed by the kernel. The key functions of the kernel can be summarised as follows:
Determines which process is the next on the central processing unit (CPU), when it will start, and how long it will take.
This programme keeps track of how much memory is being utilised to store what and where.
It acts as a translator between the hardware and the processes.
Receives service requests from processes through system calls.
The kernel is hidden from the user if the developers implement it correctly. It runs in its own space, known as the kernel space. It manages memory allocation and keeps track of where everything is stored in the kernel space.
The user space is the environment in which files and web browsers are shown to the user. A system call interface is used by these applications to connect with the kernel.
