The TCP/IP Model

The TCP/IP Model is a way of connecting computers and other devices to create a network. It stands for Transmission Control Protocol/Internet Protocol and is the foundation of the Internet. Think of it like a highway system. On a highway, you have roads that connect different cities. The TCP/IP Model is similar in that it creates pathways that allow computers to talk to each other. These pathways are known as “connections” and are made up of different protocols, such as TCP, IP, and HTTP. When you send an email, for example, the TCP/IP Model is what allows it to be sent from one computer to another. It does this by breaking the message into small packets, which travel from one computer to another until they reach their destination. Fun fact: TCP/IP was first developed in the 1970s by two researchers at the United States Department of Defense.
