Protocols and Architecture

Protocols are standardized rules that devices follow to communicate effectively over a network, ensuring data is transmitted correctly and securely. They specify how data is formatted, transmitted, and acknowledged. Architecture refers to the overall design and structure of a network system, including how devices connect, how data flows, and how components work together. Together, protocols and architecture define how devices interact within a network, enabling smooth, reliable communication—similar to traffic rules (protocols) within a city’s road system (architecture).
