The Internet can sometimes seem profoundly obscure or magical. However, at its core, it is an information delivery system, functioning a bit like a package delivery service. In fact, I will use the analogy of the postal service to explain the various aspects of the functioning of this communication system.
This year marks the 25th anniversary of the launch of the World Wide Web for the general public. In 1991, Tim Berners-Lee posted the seminal “WorldWideWeb Project” document in various Usenet newsgroups and provided the alpha version of a basic Web browser, the Line Mode Browser, on an FTP server for downloading. This was the start of a world-wide Web that could be used and tested by any Internet user.
