When we want to install Linux on our PC, in general, before doing this we look for information on the subject, by doing so we have access to the wide variety of existing Linux distributions, the most famous being Ubuntu, Fedora, Linux mint, they should.
All of these are modified versions of Linux, which they share the same Kernel, the so-called Kernel, is the kernel of the operating system, which takes care of all the processes and threads of the system, this has the main feature, of being open source, and thanks to this is that there are so many Linux distributions.
What is the kernel?
An operating system is based on several lines of code one after the other, these normally express instructions that must be followed, they are normally interpreted by the computer's BIOS, but these lines of code are nothing more than that, unless it is available of the Kernel, since this is the core of everything, and the one who knows how to interpret the lines of code.
When do you use Linux, you can select the one you want to use, you can from the command terminal disable some functions and activate others, this is because in many companies Linux is simply used as a command console, since the graphics section is left more for home computers and desktops.
In daily use, the Kernel does not interact directly with the user, since it is a set of threads that run without user supervision, the heart of the system has full access to all computer hardware, from peripherals to drives. storage and processing.
How does the kernel work in Linux?
As we already know, the Kernel works like the Linux system kernel, this is based on a Unix clone and they share many similarities, as we already know, it has control of all PC hardware.
Therefore, it has the power to control the use of the RAMAs Linux is a highly compatible system with many applications, RAM management is vital for the proper functioning of the system, so it is also a good idea to know which applications are the best when it comes to using Linux, as they are made specifically for this system .
Furthermore, the kernel has the ability to use and manage the our processorAs is known, current computers have a large number of cores and threads, so the kernel must be able to efficiently divide the tasks between each of the cores in order to achieve the best performance.
Currently the Linux kernel allows you to do almost anything, and you don't need so much knowledge to learn how to use it, it's good to know it and get rid of the idea that Linux is just a console, in it you can download a large number of programs from the internet, making your distributions a great experience.
What versions of the Linux kernel are there?
The Linux kernel has undergone changes over the years and since its departure in 1991 it has a total of 5 versions, when we install a Linux version, we realize that many times it carries a number next to the name, These numbers are what tell us which version of Linux is.
The first number from left to right tells us which version of the Kernel that version has, passing from 1 to 5, this value does not normally tend to change much, since exist alone 5 versions and the first 3 are almost totally disused of the Similarly, the number followed by it tells us which version has the distribution we are using.
It can be anyone, Ubuntu, Xubuntu, Linux mint, it is generally recommended to install the latest version, the last two values refer to the revisions of the edition and the number of critical failures the system had to test on PC or virtual machines, specially designed for this practice.
It should be noted that the more revisions it has, the Linux that we are trying to download, the better and more reliable it will be when it gets installed, as when bugs are found, patches are made and are fixed quickly.
