What is a CPU & a kernel?
The kernel is a computer program at the core of a computer's operating system and generally has complete control over everything in the system. The kernel is also responsible for preventing and mitigating conflicts between different processes. [1] .
Jun 8, 2011 · Kernel memory is the memory used by the Windows kernel. It includes memory used by core components of Windows along with any device drivers. Typically, the number will be very small, in the hundreds of megabytes.

- Monolithic Kernel – It is one of types of kernel where all operating system services operate in kernel space. It has dependencies between systems components.
- Micro Kernel – It is kernel types which has minimalist approach. It has virtual memory and thread scheduling. It is more stable with less services in kernel space.
- Hybrid Kernel – It is the combination of both monolithic kernel and mircrokernel. It has speed and design of monolithic kernel and modularity and stability of microkernel.
- Exo Kernel – It is the type of kernel which follows end-to-end principle. It has fewest hardware abstractions as possible. It allocates physical resources to applications.
Oct 5, 2023 · A kernel is the central or essential part of a computer’s operating system. It’s the main layer between the software running on your computer and its hardware. Ahead, we’ll explain what a kernel is, the various types of kernels, and what they do in an operating system.
The kernel is the essential foundation of a computer's operating system ( OS ). It is the core that provides basic services for all other parts of the OS. It 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.
The kernel exists as a protected region of virtual memory within the context of every process. Just like a normal user-mode program, the kernel contains a code segment, global data, and a heap for dynamic memory allocation.
Mar 18, 2024 · The kernel is one of the initial programs loaded up on memory before the boot loader. The boot loader is responsible for translating instructions for the central processing unit. It manages memory as well as peripherals such as keyboards and monitors.
