Linux kernel Versions

In the previous two articles, we examined the features of the Linux kernel, its architecture, and the tasks it performs. It is also important to know. that he also has certain versions that have certain differences among themselves. Let's talk about these differences further. It will be interesting.

Linux Kernel Versions

Linux operating system kernel versions can be represented as follows: versions A-B-C-D, where:

A – first of all, it was planned that A would be able to increase the number after a significant revision of the core, but at the moment, after completing the required number of edits and innovations, on average 2 times in 10 years;
B – revision, updated every 2-3 months. Some have long-term support. The last such core was update 5.10. Each revision has a significant list of changes, first of all they are checked by the tester;
C and D – in the kernel code perform the task of the error checker. C increases provided that the drivers have been updated, and D increases when the next security patch has been released. These numbers may change daily.

The obvious question is, how do I find out the kernel version? This can be done very simply. You need to use the command.

This command is as follows:

$ uname -r

Simply put, the kernel acts as a working tool, and its goals can be any - launching a terminal and so on.
