The kernel performs its tasks, such as running processes, managing hardware devices such as the hard disk, and handling interrupts, in this protected kernel space.
The kernel’s interface is a low-level abstraction layer.
When a process makes requests of the kernel, it is called a system call.
Is kernel A hardware?
A computer kernel interfaces between the three major computer hardware components, providing services between the application/user interface and the CPU, memory and other hardware I/O devices. The kernel provides and manages computer resources, allowing other programs to run and use these resources.
How an operating system interacts with hardware?
In order for the operating system to talk to your hardware, it needs drivers. Drivers teach the operating system to interact with each bit of hardware. Graphics cards, sound cards, networking cards, USB peripherals, and everything else you connect to your computer relies on drivers.
What is the function of kernel?
The kernel is a computer program that is the core of a computer’s Operating System, with complete control over everything in the system. It handles the rest of start-up as well as input/output requests from software, translating them into data-processing instructions for the central processing unit.
