Computers and Internet
A short history of how the internet begun, this remarkable network that nowadays spread all over the world with an amazing speed. We cannot imagine life without it any more. Let’s see how it all begun
At the very beginning, the Internet was an experimental program for the American military, in the 60’s. In this project, the military paid for the costs involved in researching a network named Arpanet, which connected universities and military bases. In 1974 the first independent communication hardware was completed, in essence the first versions of TCP and IP, invented by Vincent Cerf and Robert Kahn. In the 80’s the military network was transformed into a different network and Arpanet was renamed "Internet."
The Internet can be described as an open system. Through "Open System" we understand that the structure is no secret, meaning its creator has made the design detailed enough so that other people can come along and make their own products. Other examples of open systems are UNIX and Linux. Examples of privately owned systems are Microsoft Windows and Mac OS.
The primary function of the Internet is the exchange of data between computers; to accomplish this, every computer of the Internet network has an IP address.The determination of the IP address, coming from the name, is done by interrogating a server for the Domain name. DNS =the multitude of all this name-servers.
Some say that everything you might need you can find on Internet, and you can live forever just sitting in front of your computer. Well, you won't live forever, but you can certainly do many things, like accessing information, enjoying yourself, and even buying your groceries.
