First Class :)

Our first class started off with an interesting group activity, and at the end we did learn that in the world of the internet, comes many technologies,development tools, uses and social/business issues. Our group provided one example of internet technology which was VoIP. Voice over Internet Protocol is simply the transmission of voice traffic over IP-based networks. Due to the low cost of this technology compared to traditional telephone networks, it is in high demand of consumers. In fact, If you have a fast Internet connection (DSL or cable) you can make PC-to-PC phone calls anywhere in the world for free! If you would like to make a PC-to-phone connection, however, there's usually a charge for this but definitely much cheaper than your regular phone service. To better understand how this works, here is a VoIP Diagram:

We also learned a bit about the Infrastructure of the Internet and specifically about the OSI and TCP/IP Models. Here is a link to the OSI Model's different layers:

After our first class , I did more research about the "Internet" itself and wanted to share some interesting information : "The origins of the Internet reach back to the 1960s when the United States funded research projects of its military agencies to build robust, fault-tolerant and distributed computer networks."
