However, the Linux kernel was later adopted as the kernel for GNU (GNU’s-Not-Unix) operating system, which was programmed to be a free substitute for Unix. The Linux kernel is a Unix-like operating systems kernel that Linus Torvalds originally established in 1991 for personal computers that were i386 based. It is a free, open-source, and multitasking operating system kernel. The Linux kernel falls under the Monolithic kernel types. An address space is the amount of memory dedicated to all usable addresses for a computerized entity, such as a server, a device, or a file. What distinguishes these kernels is the number of address spaces they are compatible with. ![]() Usually, Kernels can be categorized into three groups based on their architecture: Monolithic, Microkernel, and Hybrid. All other tasks an OS kernel performs can be categorized under these three. ![]() Also, it plays an important role in the smooth running of computer operations, such as storage, processing, file management, etc.Īn operating system’s kernel performs several functions it provides the necessary interaction interface for users and computer applications, oversees the operation of significant hardware devices, and ensures the proper running of applications. It provides essential services to the entire operating system. ![]() The Kernel has always been considered one of the basic building blocks of a computer’s operating system. The kernel is the primary layer between the operating system and computer hardware.
