Blog 4, Linux kernal numbering

The Linux kernel is constantly in a state of development. Because of this there are many different versions of the Linux kernel in use today. If you are going to be working with Linux, or even discussing Linux with someone, it is very important to know which version of the Linux kernel you are working with. Additionally, knowing which version you are currently using allows you to determine if it is necessary to upgrade your kernel to a newer version.

There are 2 basic types of Linux kernels available: a production version, that is ready for general use, and an experimental version, which is still under development. If you are upgrading your personal Linux kernel, you would want the production version. For versions released prior to 2004, which version you are downloading could be determined by the second number in the kernels 4 number numbering scheme. If the second number (the number of the revision: the first number is the version) is even it is a production version. If it is odd it is an experimental version. For current versions of the Linux kernel 9version 2.6.0 or later) the letters "rc" are added after he numbers to indicate a version under development.

You can easily determine which kernel version is on your computer by using the uname command.

This numbering scheme does not seem to have any real disadvantages, as long as you are very careful not to mistakenly download a developing version of a kernel.
