Have you ever been stumped in a configuration file or some other installation for a web based program when asked for an absolute path? The thing that you are installing will not work because the application insists on you entering the absolute file path yourself which you simply do not happen to know. There's no way around it, you have to get absolute path to the file or folder where items are going to be stored or used by the application. You are thinking to yourself 'why can't the stupid program figure it out on it's own?' That's not going to be helpful though, you just have to know how to find absolute paths.
Building websites using static web pages becomes unwieldy once the content starts to add up. They are also often difficult to update. Finding content on the site is harder since a static site usually doesn't have a search function.
