File Transfer Protocol makes it possible for files to be copied between machines. There are special clients, who can only do FTP, but Dreamweaver also has FTP functionality built in. So you can e.g. copy an XHTML document from your own computer to a webserver with FTP.
We talk about upload/put and download/get. In Dreamweaver put is symbolized by an arrow pointing up, and get by an arrow pointing down. So in this sense the internet is "up". We put stuff up on the internet, or pull it down from the 'net.
