What is a kernel?

Answer 1

A kernel is the core component of an operating system that manages system resources. It controls the allocation and use of computer hardware such as memory and CPU time. Essentially, it acts as a bridge between applications and hardware.

Answer 2

A kernel is the core component of an operating system (OS) that controls the system's resources and provides low-level services to other parts of the OS. It manages the CPU, memory, and input/output devices, and provides a layer of abstraction between the hardware and software. The kernel is responsible for starting the OS and managing processes, memory, and system calls. It also provides security features such as access control and authentication.
