When web hosting companies say 'unlimited' they do not really mean unlimited. When some people chose to say things that generally interpret it to mean what they want it to mean. They obviously do not offer you all the resources on the planet for a meager $ 3 a month!
The problem arises when you do not know what each individual provider means when they all say the same thing. The beauty of the English language is that words themselves are susceptible to different meanings. For example, in one case, a jet ski collided with a boat and the boat ownerought damages under the Merchant Shipping Act, a law providing for damages when “vessels” collide. A question wasose when a jet ski could have fitted within the legal definition of a 'vessel' and the court found it as they put it – comical to do so.
Words are indeed the only means that we have to communicate, and when one word – whatever it may mean – starts having a different meaning based on mass use by people, the majority of people using the word must prevail over the overly technical minority of people who intends to give it an archaic meaning.
The term 'unlimited hosting' is used very broadly in the web hosting business by many and is also accommodated by a qualification to that effect by the same group of people. Hostgator, a popular web hosting company touts an unlimited web hosting plan on their website, and also posts the following clarification somewhere deep in their support FAQ section; “We reserve the right to refuse service to anyone. Any material that, in our judgment, is obscene, threatening, illegal, or violates our terms of service in any manner may be removed from our servers (or otherwise disabled), with or without notice. ” (Source: Hostgator's website at http://www.hostgator.com/tos )
This does not make Hostgator bad or evil in any way – but being one of the largest web hosting providers, it sets the standard and influences conduct by other smaller web hosting companies. It sends them a signal, that you can first make a lofty promise to your customers and then do just as you please and pick and chose whiche customers you like or do not like.
“When companies say unlimited, what they mean is that they do not meter or limit you on that item. But just because you can have an unlimited amount of something that does not mean it is physically possible to consume an infinite amount. infinite. ” (Source Dreamhost's website at http://support.hostgator.com/articles/pre-sales-policies/how-much-traffic-can-i-have ).
Note that not all uses of the word “unlimited” in a web hosting package is necessarily Humpty-Dumpty-speak. All web hosts allow you to create unlimited email addresses. When these hosts advertise such features, they usually really mean it – because the technology really does not limit creating email addresses.
These features are usually limited by the other aspects of your hosting account anyway, like disk space, which is why a host will probably not bother to restrict the number you use.
