Domain application protocol

Domain application protocol is a way for two different computers (or devices) to communicate with each other over the internet. It is like a set of guidelines that two computers use to understand how they should talk to each other. For example, one computer will tell another computer what it wants to do, and the other computer will respond with a way to do it. One example of a domain application protocol is the Hypertext Transfer Protocol (HTTP). This is the protocol that is used when you are viewing a website in your web browser.
