When you open a website, send a message, or watch a YouTube video, many technologies work together in the background. As a beginner in DevOps, understanding these basic networking concepts will help you understand how applications communicate over the internet.
**What Is a Protocol?
A protocol is a set of rules that devices follow when communicating with each other.
Think about two people having a conversation. For communication to be successful, both people must speak the same language and follow simple rules, like taking turns to talk and listening before responding.
Computers work the same way. They use protocols to know how to send, receive, and understand information.
