Answer: A
The common gateway interface (CGI) is a standard way for a
web server to pass a user's request to an application
program and to move data back and forth to the user. When
the user requests a web page (for example, by clicking on a
highlighted word or entering a web site address), the server
sends back the requested page. However, when a user fills
out a form on a web page and sends it in, it usually needs
to be processed by an application program. The web server
typically passes the form information to a small application
program that processes the data and may send back a
confirmation message. This method, or convention for passing
data back and forth between the server and the application
is called the common gateway interface (CGI). It is part of
the web's HTTP protocol.
