ISO/IEC 7498-1

ISO/IEC 7498-1, also known as the OSI Reference Model, is a framework that standardizes how different computer systems communicate over a network. It divides this process into seven layered functions, such as handling hardware connections, data transmission, and application services. Each layer performs specific tasks and interacts with adjacent layers, ensuring that diverse systems can understand each other regardless of their underlying hardware or software. This structured approach helps develop interoperable network protocols, making communication reliable, efficient, and scalable across various platforms and technologies.
