Chapter 2. Networking Basics > Network Protocols

Network Protocols

In this chapter, we talk in general about transferring data, but a few words are in order about how that actually happens. You don't need to know this information to set up a network, but you may find it handy when you try to make certain things work.

All communication between computers takes place according to a set of agreed-upon rules, called a protocol, and often informally (and sometimes inaccurately) called a standard. It's exactly the same as communication between people, where the agreed-upon rules are called a language. A network protocol is just that, the language that two computers must speak to understand one another.
