What Link is
Text or images on a Web page that a user can click on in order to access or connect to another document. Links are most commonly thought of as the technology that connects two Web pages or Web sites. Once you click on a link, it could trigger a variety of events: It could "jump" to a different page or to another place on the same Web page; it could link to a file that will start downloading to your computer; it could trigger the launch of a helper application that will then process the clicked-on file, it could launch your e-mail program so you can send a message, and so on. What actually occurs when you click on a link is determined by the file's MIME type and the way your computer system is configured (or set up) to handle that MIME type. For example, browsers are configured to display all files that have HTML in their MIME extension. Links are also called hyperlinks, hypertext, and hot links, and they are coded in HTML by Web page authors or Web developers. The basic HTML code for using text to link to a Web site's homepage.
The meaning of FTP (File Transfer Protocol)
The standard method for downloading and uploading files over the Internet. With FTP, you can login to a server and transfer files (meaning you can "send" or "receive" files). Some sites have public file archives that you can access by using FTP with the account name "anonymous" and your e-mail address as the password. This type of access is called anonymous FTP. Macintosh owners use a program called Fetch; one of the best FTP programs for Windows is called WS-FTP. Knowing FTP is necessary (and easy) if you want to create your own Web site.
Note: You may also hear this noun used as a verb. For example, "I just finished FTP'ing the last of the files." Or, "I FTP'ed the new images to the site last night."
