3. CGI - Perl is the most commonly used language for CGI programming on the World Wide Web. The Common Gateway Interface (CGI) is an essential tool for creating and managing comprehensive web sites. With CGI, you can write scripts that create interactive, user-driven applications. CGI allows the web server to communicate with other programs that are running on the same machine. For example, with CGI, the web server can invoke an external program, while passing user-specific data to the program (such as what host the user is connecting from, or input the user has supplied through an HTML form). The program then processes that data, and the server passes the program's response back to the web browser.
4. Modules/packages, more OOP
