FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The kernel is the lowest level of the operating system. It manages the operations of the computer and the hardware most notably memory and CPU time. There are two types of kernels: a microkernel, which only contains basic functionality; a monolithic kernel, which contains many device drivers.

Detailed explanation-2: -At the heart of an OS is the kernel, which is the lowest level, or core, of the operating system. The kernel is responsible for all the most basic tasks of an OS such as controlling the file systems and device drivers.

Detailed explanation-3: -The kernel’s interface is a low-level abstraction layer. When a process requests a service from the kernel, it must invoke a system call, usually through a wrapper function. There are different kernel architecture designs.

Detailed explanation-4: -Functions of a kernel include scheduling processes, resource allocation, device management, interrupt handling, memory management, and process management.

Detailed explanation-5: -If we think of the Linux operating system in terms of layers, the kernel is the lowest layer. It interfaces directly with the computer hardware and is responsible for allocating and managing the resouces available to programs.
