|TCP/IP is the most used network protocol nowadays. In this tutorial we will explain how it works in a very easy to |
|follow language.                                                                                                   |
|So, what is a network protocol anyway? Protocol is like a language used to make two computers to talk to each       |
|other. Like in real world, if they are not talking the same language, they cannot communicate.                     |
|Before going further, we recommend you to read our tutorial The OSI Reference Model for Network Protocols, which is|
|a primer for understanding how network protocols work. Consider the present tutorial as a sequel to our OSI         |
|Reference Model tutorial.                                                                                           |
|TCP/IP is not really a protocol, but a set of protocols – a protocol stack, as it is most commonly called. Its     |
|name, for example, already refers to two different protocols, TCP (Transmission Control Protocol) and IP (Internet |
|Protocol). There are several other protocols related to TCP/IP like FTP, HTTP, SMTP and UDP – just to name a few.   |
|Don’t worry about this for now; we will explain all you need to know about them later.                             |
|TCP/IP architecture can be seen on Figure 1.                                                                       |
