Document Summary
The internet is not a technology, but a technology system. It is a component of other existing technologies, such as the server and the computer. What makes the internet different from the other forms of communications is that messages are sent through the internet using packet switching technology. Packet switching technology involves taking a digital packet (a message), breaking it up into smaller packets which contain the same address. This system guarantees that your message will get to your intended sender, no matter which server or path it takes to get there. Each packet is structured in the following way. The headers and footer allow the message to get to the correct location. Arpanet - considered to be the grandfather of the internet . It was the first system to use the packet switching technology system. Developed by paul baron in the united states, as well as donald davies in england.
