The Linux Kernel provides the foundation for a community of open-source Unix-like operating systems. Linus Torvalds released it for the first time on September 17, 1991.
The fundamental difference between Windows Kernel and Linux Kernel is that Windows Kernel is a commercial software that comes with the Windows Operating System, whereas Linux Kernel is an open source software that comes with the Linux Operating System. The kernel is the operating system's brain.
The Linux® operating system is a free and open source operating system (OS). An operating system is the software that controls the hardware and resources of a computer, such as the CPU, memory, and storage. The operating system lies between applications and hardware, connecting all of your software to the actual resources that perform the work.
A "kernel hacker" is a developer who works on the Linux kernel code. Because the Linux kernel is open-source, a significant community of maintainers has sprung up to keep it up to date and improve its quality. Kernel hackers are who they are.
A computer operating system's kernel is the heart of the system (OS). It is the core of the operating system that offers basic services to all other components. Process and memory management, file systems, device control, and networking are all handled by this layer, which sits between the OS and the hardware.
