What is a protocol? |
|
Answer» A protocol is a set of rules that govern how two or more parties interact with each other. It is a way of specifying how data should be exchanged between two or more parties. Protocols are often used to control the flow of data, such as when sending emails or transferring files. The most common type of protocol is the HTTP protocol, which defines how to exchange data between a web server and a web browser. HTTP is used by many websites to transfer data such as images, videos, and text. |
