What is the Linux Kernel

Maybe we know that there are so many Linux distributions out there, but they all have one thing in common which is the Linux Kernel. Many Linux users still don't know what a Linux kernel is and how to check it. So let's take a look at your Linux Kernel version and why it's needed.

What are Kernels?

Every operating system uses a kernel. Without a kernel, you can't have a really working computer. You may see and interact with a lot of different software, but it's the kernel underneath that does a lot of the grunt work. The kernel serves as a bridge between your computer's hardware and the software you want to run. This allows your device to talk to other hardware devices via drivers that are included in the kernel (or installed later in the form of a kernel module).

With the kernel, when an application wants to do something (say change the speaker volume setting), the application can send the request to the kernel, and the kernel can use the available speaker drivers to actually change the volume. The kernel is also involved in resource management.

Because it has to make sure that there is enough memory available to run the application and to place the application in the right location in memory. The kernel tries to optimize the use of the processor so that it can complete tasks as quickly as possible. Failures can lead to deadlocks, where the entire system crashes because one application takes up the resources of another.

What is the Linux Kernel?

It's actually not technically correct to think of Linux as a complete operating system. Linux actually refers specifically to the kernel, named after founder Linus Torvalds. Everything you see on the screen comes from other projects and developers. Torvalds created the Linux kernel in 1991. Initially the project was called Freax (a combination of “free,” “freak,” and “UNIX”). But a coworker prefers the Linux name. Eventually Torvalds released the first Linux version in 1992 under the GNU copyleft license, which was a big part of the project's success.

Much of the Linux desktop experience comes from the GNU Project, an older initiative that has created a nearly complete desktop operating system. All it needs is a kernel, and Linux fulfills that need. This is why some people refer to the OS as GNU/Linux. Other free and open source desktops, such as FreeBSD, look and feel like Linux because they run most of the same GNU software.

Since the Linux kernel is available under the GNU license, there is little interest in continuing to develop a separate kernel as part of the GNU Project. And rather than creating other competing kernels, such as those found in Windows and macOS, many companies are choosing to use and contribute to the Linux kernel instead. The Linux kernel has grown into a huge project containing millions of lines of code. Thousands of people, and more than a thousand companies, have contributed to the development of the kernel. It is one of the most prominent examples of open source and free software in the world.

What is the Linux Kernel Used For?

Although Linux is still a relatively good desktop operating system. Thanks to Android, the Linux kernel now supports most smartphones in the world. Appears on all types of mobile devices, including wearables and cameras. Linux powers the 500 most powerful supercomputers and much of the internet infrastructure. When you think of the cloud, you think primarily of interconnected Linux-powered servers.

Linux started out as a hacker project, and while the kernel has approached unimaginable corporate adoption, it still powers hardware for tamers. A tiny Raspberry Pi for Rp. This 500,000 is a Linux powered computer the size of a credit card, totally open for people to modify and use the project as they see fit and not to forget competitors like Pine64 have helped drastically reduce the cost of computing.

How to Check Linux Kernel Version

The kernel is still under active development, so new Linux versions come out all the time. The easiest way to see which release is on your machine, which will work on all versions of Linux, is to use the uname command. It is a command line tool that provides system information. You can find the Linux kernel version you are using by opening a terminal window and typing the following:

uname -r

Uname -r Kali Linux

Currently admin is running Linux kernel version 5.3.0-times-amd64. Let's break down what this means.

  *5 refers to the kernel version.

  *3 refers to the current major revision.

  *0 refers to the current minor revision.

  *kali refers to a Linux OS distro.

  * amd64 refers to the operating system bit.

If the explanation above is concluded, it means that the admin is now running the Kali Linux 5 64-Bit version

Should Update Linux Kernel

For the most part, the Linux kernel operates silently in the background. You don't know it's there, and you have little reason to think about it. For the most part, the best way to update your Linux kernel version is to upgrade to the latest version of your Linux operating system of choice. New versions of Ubuntu and Fedora, for example, come out roughly every six months and carry newer versions of the Linux kernel.

While most kernels are invisible, there are several reasons to upgrade to a newer Linux kernel. Unlike on Windows, Linux hardware drivers are bundled with the Linux kernel. So, if you have a relatively new PC or laptop with speakers, Wi-Fi, or a touchpad that your Linux version hasn't detected yet, maybe you should wait for the newer version. If a new Kernel is released, it will come with increased stability and speed, so that your computer can run more smoothly on one version compared to another.


So what is the Linux kernel? It is a major component of the Linux operating system and is the core interface between computer hardware and processes. This is what can lead to communicating between the two, and can manage resources as efficiently as possible.
