What is a Protocol?

Protocol in the context of the internet refers to a set of rules that determine how data is transmitted and received over a network. These rules ensure that communication between devices, such as computers or servers, happens smoothly and securely. Common protocols include HTTP (Hypertext Transfer Protocol) for websites, FTP (File Transfer Protocol) for transferring files, and HTTPS (HTTP Secure) for secure communication.

Protocols are important because they establish the guidelines for how data is exchanged, ensuring compatibility, security, and efficiency. Without proper protocols, communication over the internet would be chaotic, unreliable, and insecure.
