WebNov 9, 2024 · Definition The kernel is the most important part of the operating system. It is the primary interface between the hardware and the processes of a computer. The kernel connects these two in order to adjust resources as effectively as possible. It is named a kernel because it operates inside the OS, just like a seed inside a hard shell. WebA microkernel is a minimal computer operating system kernel which, in its purest form, provides no operating system services at all, only the mechanisms needed to implement such services, such as low-level address space management, thread management, and inter-process communication (IPC).

Characteristics of Modern Operating System

WebA microkernel is the type of operating system architecture that is useful in the same way as the other architectures are and is used for file management, memory management, and the scheduling of the processes. WebIt is the main layer between the OS and underlying computer hardware, and it helps with tasks such as process and memory management, file systems, device control and networking. During normal system startup, a computer's basic input/output system, or BIOS, completes a hardware bootstrap or initialization. firststarhr login
