Linux is the generic term for a family of free operating systems based on a common 'open source' kernel and packaged into what are known as distributions. Each distribution has it's own merits but most do the same, often better, job as 'paid for' operating systems like Microsoft Windows or Apple IOS.

Ubuntu (pronounced ooo-BOON-tooo) is an example of one of many excellent Linux based distributions [i.e. full operating systems] and is produced by Canonical who make available as a free download resulting in it being used daily by millions of people around the world from professionals to beginners. It is an open source Debian-based and sponsored by Canonical Ltd.

There are many other Linux distributions available [each with it's own focus - see link below to "Additional Linux Distributions"] but for the average user it is fair to say that Ubuntu is generally accepted as being one of the most popular and easy to use.

Canonical provide regular minor maintenance updates and there are also two bigger releases of Ubuntu each year. The first in April the second in October, and the numbers in their names reflect which they are.
