Structure of Networks and Webs

Structure of Networks and Webs - module W601

How does information get to your computer screen from the other side of the world? How does information that you enter onto forms get correlated elsewhere to reserve you a place on an airline flight, or to ship you the coffee beans you ordered? In this module, we look at the structure of the networks, such as the Internet, and the various services provided on them. This is useful background information for you if you're going to be responsible for a web site, or if you're going to be writing programs to run on computers on the Internet.

This topic is presented on public courses Technology Background for PHP, Getting Public Sector Data on Line, Deploying LAMP - Linux, Apache, MySQL, Perl/PHP, Linux Administration
