A LiveCD is a special version of Ubuntu (or Linux in general) that is built to run only off the CD without needing to be installed. This makes a great tool to test hardware, do system recovery or show new people Ubuntu. As of Ubuntu 6.06 (Dapper Drake), you can also install off the LiveCD.
Downloading the LiveCD

Download Ubuntu 6.06

Using the LiveCD
