A static website is a website that doesn't change often. Once or twice a month at most. These websites consist out of a separate web page file for each of the pages. So, chances are, if there are 5 pages, then there are 5 .html files (that excludes things like images and style sheets, etc.). If you have a small business, with a limited budget set aside for marketing, then a static website may just be a good way of getting yourself an online presence.
