Its as lookforAdam says, all the others are way off the mark.
A hit is about anytime a browser requests some information from your website and a page view is when a complete page is viewed. Both are very misleading and are there for historical and adminstrator information (and because they are easily extracted from the server logs).
What you really want to know is the number of unique visitors, some log analysis data will give you this.
But again be warned this is misleading as it really refers to the number of unquie visits from browsers which does not mean unique people. Consider someone opens your site in a browser, closes it and then goes back to it two minutes later, this can be recorded as two unique visitors.
With most of this stuff look for changes in magnituted of the results to give you a feeling for how your site is going. The other and somewhat better option are to inlcude code on your site to monitor users, such as Google Analytics
