Have you got an ISO file? If you have an ISO, it will be about the size of a CD. If this is a small file, all you have is the file to get the ISO.

If you have the ISO file, run a md5sum check on the file to verify it is a good file. After you know it is good, go here -->http://www.linuxquestions.org/linux/answers/LQ_ISO for instructions on ways to burn the ISO to a CD.

If you have the small file, you will need to download the ISO file. Torrent files are small.

...about small ".torrent" files
 

...and if you only have the small file which has the ".torrent" extension then for downloading its contents you use a "Bittorrent client". (If you have a recent version of the Opera browser you can use that too.) To find out what's a suitable Bittorrent client to try you can search LQ for threads about bittorrent. To install a client, and if you still run Ubuntu like you posted in your other thread, then you can use any of your menu selections ("Add/Remove", "Update Manager"), package manager (Synaptic) or commandline tools (apt-get, aptitude) to search for the term "torrent" or "bittorrent". Note depending on your available bandwidth, the bandwidth and amount of peers downloading torrents might take a while, but you can stop and resume at any time provided the torrent still has peers.

As I recall it, I downloaded a .torrent file, right-clicked on it, and it told me I needed a client and gave me a list of them to choose from. I selected "bittorrent", and down everything came. ... Not rocket science.
