OSI model

The OSI Model is a fundamental communication model used to standardize network interactions and protocols across diverse systems. It organizes communication into seven distinct layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. Each layer serves a specific role, facilitating interoperability and simplifying troubleshooting. By segmenting processes, the OSI Model ensures that data transfer between devices is seamless, secure, and efficient. It provides a framework for understanding how network protocols and hardware components interact, enabling the development of robust networking solutions. Widely adopted in networking, this model is a cornerstone of modern communication technologies and system design.
