Meta tags are used to display metadata about the HTML page and are used predominantly to give the page a title and description.
The meta tags are at home in the header of the HTML page so they don't display on the page itself. The metadata is there for benefit of the users browser to provide info like the title of the page or how often to refresh and also in a big way for search engines. Search engines will use this meta data to help define the subject of your page and what to rank it for. The meta tags are by no means the only thing you need to rank highly but they are part of the puzzle.
