CGI (Common Gateway Interface)
A CGI is a program that translates data from a web server and then displays that data on a web page or in an email. CGI involves the transfer of data between a server and a CGI program (called a script). This allows HTML pages to interact with other programming applications. These scripts make web pages interactive. Page counters, forms, guest books, random text/images and other features can be driven by CGI scripts. Some servers have pre-installed/pre-defined CGI scripts, meaning that the scripts are already installed on the server for you to use on your site. Some servers permit user-defined or custom CGI scripts, which means the site owner creates his/her own CGI script and runs this custom made script on the web site. Not all servers allow user-defined (custom) scripts for security reasons. Almost all hosting companies offer CGI today. If you think you will need forms on your web site, CGI could be a key requirement.
