Task 1 : The Impact of Communication Technology [P1]

Definition of internet: The Internet is a global system of interconnected computer networks that use the Internet protocol suite (IP) to connect devices around the world. It is a network of networks comprising private, public, academic, business, and governmental networks locally to the global scope, which is linked to a wide range of electronic, wireless and optical networking technologies. The Internet brings a variety of resources and information services, such as connected hypertext documents and the World Wide Web application, electronic mail, telephone, and file sharing

Definition of Worldwide Web: The World Wide Web (shorten as WWW) is an information space where documents and other web resources are identified by Uniform Resources Locater (URLs), which are linked to hypertext links, and accessible via the Internet.

How does the internet works?
The Internet can be described as a network of computers around the world. While some of its servers have more power than others, it is largely centralized. The Internet itself is just hardware and its connection. This protocol allows different types of access.

Hardware that dominates the Internet is the most important component, and connections between different nodes allow it to reach the entire planet. Various traffic to the right destination, but no centralized server that controls all traffic. Although all infrastructure currently direct traffic properly, the body can not control compliance effectively.

The Internet refers to more than the World Wide Web, which most people mean when they discuss the Internet. FTP connections use the Internet as well, and many companies and organizations have developed their own protocols. 

Domain name server servers are administered by an international group. The Internet location is accessed through a series of numbers, called an IP address, and a DNS server translates a website's name, such as google.com, to the same IP address. This DNS server facilitates the Internet for end users, and they allow the server to change the IP address they use.
