Ubuntu may just be one of the most popular distributions that the Linux community has developed over the past five years. What has made this distribution so popular is not only that it’s available for free download but you can also get a free CD mailed to you. This makes it easy for those who do not or don’t know how to burn a CD image of an .iso file. Overall the folks at Ubuntu have made it easy to try their product. It can be run as a live CD and also installed on a hard disk.
