"When I use a word," Humpty Dumpty said in a rather scornful tone, "it means just what I choose it to mean -- neither more nor less."

In the same way, when web hosts use the word "unlimited" to say that you get "unlimited disk space" or "unlimited bandwidth" (or its equivalent "unlimited data transfer"), the word "unlimited" usually gets redefined to some other meaning, at the web host's discretion. The exact meaning varies from host to host, in the spirit of Humpty Dumpty, but it invariably means the opposite of the "unlimited" found in the English language."
so in the spirit of the above unlimited is a bunch of croc. read the nice full article at The Real Meaning of "Unlimited" in Web Hosting (thesitewizard.com) but like I said before unlimited or in the terrabytes is a bunch of shit. Any host that advertises that I would run far away from.... 200 visitors and 1.5 gigs of BW is not a lot by any real standards and sounds like crap.

just as a small example (meaning do your homework first) look at hosts like SYN Hosting - Affordable, Reliable & Secure Web Hosting and check Web Hosting Forum - Web Hosting Talk - The largest, most influential web hosting community on the Internet for more info.
