"WAMP" is an acronym formed from the initials of the operating system (Windows) and the package's principal components: Apache, MySQL and PHP (or Perl or Python). Apache is a web server, which allows people with web browsers like Internet Explorer or Firefox to connect to a computer and see information there as web pages.
Windows - check
MySQL - hmm, DokuWiki is file-based, I don't need this then; check.
So I need to install Apache?
