Reviewed by: Robert Hampton

In the context of computer science, a protocol is a set of rules and standards that allow computers to communicate with each other. Imagine it like a common language that computers use so they can send and receive data correctly. For example, when you browse the internet, your computer uses protocols to connect and transfer data from web servers to show you a website. These protocols ensure that different devices and systems can work together smoothly, even if they come from different manufacturers. Understanding protocols is important because they help keep data secure and make sure that everything works as it should.
