Indeed, its a computer program like any other (So is any other website on the internet).

Some people offer hosted MW (where they take care of those details for you). Some charge for it, while others offer such things for free (Typically the free one's either require adverts and/or require the wiki to be on a topic of interest to the general public) There's a bunch listed at Comparison_of_wiki_farms, but there's many others not listed there you can find by googling.
