The Common Gateway Interface (CGI) is an accepted standard for interfacing Web servers and external applications. Web servers and external applications. Web servers were originally designed to serve static HTML documents along with other associated static files. A web browser that communicates with a Web server limits its functionality to serving static pages. It displays…
Virtual worlds are created using a computer language called Virtual Reality Modeling Language (VRML). this language instructs computers on how to build 3D geometric objects. VRML is a 3D equivalent to HTML, but with more capabilities than just putting a 3D shop on your web page. Imagine the Internet as a place where you could…
