What is the Internet

How is the Internet connected

Gateway

A Gateway is basically Donald Trump. It controls the wall between two different systems, for example on your home router to connect from your devices to internet. However, unlike the Donald, Gateways can translate. They translate the current protocols for the new system to understand. This allows two different systems with different protocols to be connected. Without this, data would be kept outside the border and could not communicate across it - welcome to Trump's America.

How is data transmitted

Packet Switching

Circuit Switching

The End to End Principle

The devices that are communicating should be the endpoints of the communication with no external input. The Internet serves as a medium to carry traffic between them but makes no changes the data involved. Therefore the transmitting devices control every aspect of the transmission, allowing security (through encryption) and the detection of errors, which maintains the integrity of transmitted data.

Using this principle allows the Internet to easily grow because there is no direct control over the number of endpoints.
