Forms are web pages comprised of text and "fields" for a user to fill in with information. They are an excellent way of collecting and processing information from people visiting a website, as well as allowing them to interact with web pages. Forms are written in HTML and processed by CGI programs. The output can be sent as an e-mail form, stored online, printed, and/or returned to the user as an HTML page. When you enter a keyword in the search field of an Internet directory, you are filling in a form. It is then processed by a CGI program, returning a list of possible matches with your keyword. Forms are also used for online catalogs, surveys, requests for information, and conferencing.
