The kernel is the most important part of an operating system, the part in charge of accessing the different devices that a computer has. The kernel it also organizes the way in which the various programs that are loaded into memory are executed. In this way, the kernel takes care of the most critical aspects of an operating system, serving as a mediation between software and hardware. Although this type of differentiation between the various parts of an operating system occurs in those that are most used, it is important to note, however, that in some cases it is omitted.
The Importance of the Kernel
The operating system is the basic program that allows us to have the different possibilities offered by a computer. In the most famous operating systems, an attempt is made to differentiate that part of the system that is essential for the proper functioning of the other programs. This essential part is executed in a special way, has full access to the hardware of the computer and is always kept in memory, while other parts of the operating system can be lifted into it only when necessary. In the case of kernel, it must always be available to be used, it is the fundamental part that makes everything else work in a coordinated way.
It may be important to account for some of the core activities to understand their relevance. In a computer, different programs are continually making requests to the different resources of the same; the kernel is in charge of giving these accesses, preventing two programs from accessing the same resource at the same time; in this way, interruptions are created so that there is an order in the access.
Operation based on optimization processes
Another point to consider is the fact that the kernel It is responsible for creating and destroying processes, that is, lifting software in memory or eliminating it; it also ensures that the loaded processes interact with each other in a coordinated way. Other important functions are related to memory usage and file system management, that is, the way information is organized and stored.
As we can see, the role of the nucleus o kernel It is extremely important with regard to the operation of a computer, without it it would be impossible to have access to the different resources of the same, it would be impossible to coordinate the use of the programs that we use daily.
