Week09-FCC123 Introduction to Information Technology

 

This weeks topic was about the "Trends in the internet and WWW". We learned about the differences between the internet and the World Wide Web. Internet functions are transport mechanism. Global WAN that connects approximately 1 million organizational computer nets in more than 200 countries. Internet enables people to access data in other organization and to communicate, collaborate and exchange information around the world, quickly and inexpensively.
WWW is an application that uses those transport functions. The web handles all types of digital information including text, hypermedia, graphics and sound. Later on we learned about Web-based Computing. The web current computing models include server side computing (CGI) and client side computing (Applets) and were initially designed for processing fill-out forms. Then we learned how internet infrastructure works. For example, instant messaging. When log in to IM server, the server determines in any of user established friends, family, coworkers called buddies are online. When the sender send instant voice or video communications to online buddies, the message travels through a messaging server and then to the online buddy's computer.
