Protocols
Protocols are formal sets of rules and conventions that govern how data is transmitted, formatted, and processed between devices or systems in a network or computing environment. They define the syntax, semantics, and synchronization of communication, ensuring interoperability and reliability across different technologies. Examples include HTTP for web communication, TCP/IP for internet data transfer, and SMTP for email transmission.
Developers should learn protocols to build networked applications, integrate systems, and ensure secure and efficient data exchange, as they are fundamental to web development, APIs, IoT, and distributed systems. Understanding protocols like HTTP/HTTPS, WebSocket, or MQTT is crucial for implementing client-server architectures, real-time features, and cloud services, enabling robust communication in modern software.
