What is Internet

Internet is a global network that connects millions of computers across the world. It uses standard internet protocol suite (TCP/IP) to connect billions of computer users worldwide. It is set up by using electronic, wireless and networking technologies. It is the fastest mean of sending or exchanging information and data between computers across the world.

Who Created the Internet?

The Internet began in 1969 as a research project funded by the Department of Defense with a goal of creating a means of communication beside telephone lines. The first network was called ARPANET (Advanced Research Project Agency NETwork). The focus was on communicating in the event part of the network was disabled. This early network was the precursor to the Internet. It was limited in function but launched the idea of a different method of communication.

How Does Information Move Across the Internet?

Information moves across the Internet much like UPS delivers packages. When you order something, it could be boxes in multiple packages because one box would be too large to deliver. A message or webpage is broken down into packets to be delivered to your computer. Each packet has addressing information so that it knows where it is going. Your message or webpage could be broken down into many packets and each packet will have the address and the number of the packet so that when it gets to its final destination your computer or email server will know how to put the packet together to make a meaningful message.

In the beginning, most information moved across telephone lines using a modem and dial up connection. This method of connection, slow and unreliable, is still available. Today, though, we have connections, such as ISDN - Integrated Service Digital Network, DSL - Digital Subscriber Line, T1 and T3 lines, that provide faster speeds. You can also get the Internet over your local cable TV lines and by satellite. No matter how you connect to the Internet, it has likely become a vital part of your everyday life.
