The Linux kernel mainly acts as a resource manager acting as an abstract layer for the applications. The applications have a connection with the kernel which in turn interacts with the hardware and services the applications. Linux is a multitasking system allowing multiple processes to execute concurrently.
How Linux kernel are made?

What is the role of an operating system kernel?
The operating system kernel represents the highest level of privilege in a modern general purpose computer. The kernel arbitrates access to protected hardware and controls how limited resources such as running time on the CPU and physical memory pages are used by processes on the system.
Is Linux written in C?
