Kernel Structure (Windows)
What is a kernel? Basically kernel is a computer program which manages input and output requests from the S/W, and then translates them into data processing instructions for the central process unit (CPU) and other electronic components of a PC.

Actually the kernel is the heart of an operating system. The task of this software is to run the programs and provide secure access to the computer’s hardware. If there are so many programs, and the resources are limited, this software called (kernel) also decides when and how long a program should run. It is also called scheduling. It might be very complex to access the hardware directly, since there’re so many different hardware designs for the same type of components. Usually kernels implement somehow level of hardware abstraction to hide the underlying complexity from applications and provide a uniform interface. This also helps application developers to develop

And a computer system can be divided into 4 components: the operating system, the application programs, the uses, and the hardware. Without operating system we cannot use the computer.
Booting Process
To start the boot procedure, turn on the PC. This is known as a frosty boot. At the point when the PC is controlled on, it performs a Power On Self -Test (POST). Since the video connector has not yet been instated, mistakes that happen right now in the boot procedure are accounted for by a progression of capable of being heard tones, called beep codes.
After POST, the BIOS finds and peruses the design settings that are put away in the CMOS memory. The boot gadget need, is the request in which gadgets are checked to find the working framework. The boot gadget need is set in the BIOS and can be organized in any request. The BIOS boots the PC utilizing the first drive that contains a working
