Week 1 (Introduction to the internet)

After the first week of com125, i have learned many facts that i did not before about the internet i used daily in my life.

Firstly, what is the internet? Most people would probably have their own definition. The technical term basically is that the internet is a global system of interconnected computer networks that interchange data by packet switching using the standardized internet protocol suite (TCP/IP). It is a "network of networks" that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and other technologies. (Thank you Wikipedia for the definition)

The other important fact about the internet is its history. How was it created? The important word is 'ARPANET'. How does ARPANET got to do with the creation of the internet we use today? Basically, ARPANET developed by ARPA of the United States Department of Defense, was the world's first operational packet switching network. After ARPANET was created, the next stage was to add desktop PCs which connected through telephone wires. After the desktop PC stage, wireless connections were the next to be added to laptops. Currently, the internet is evolving to allow mobile phone internet connectivity ubiquitously using cellular networks.

In my opinion, the internet is has become so huge that it has somehow intergrated itself into daily lives.

I'm off to bed for now, that is all folks.
