Protocol Design
Protocol design is the process of defining the rules, formats, and procedures for communication between systems, devices, or software components. It involves specifying how data is structured, transmitted, and interpreted to ensure reliable and efficient interoperability. This foundational concept underpins network protocols, API designs, and communication standards across computing.
Developers should learn protocol design when building distributed systems, networked applications, or APIs that require standardized communication between components. It is essential for ensuring compatibility, security, and performance in scenarios like web services, IoT devices, or peer-to-peer networks, where clear protocols prevent errors and enable scalability.
