ISO/IEC 7498-1 is a standard that defines the basic concepts and models for computer networking. It introduces the Open Systems Interconnection (OSI) model, which is a framework that helps different computer systems communicate over a network. The model is divided into seven layers, each with specific functions, ranging from physical connections to application-level interactions. This standard serves as a guideline for developing and implementing network protocols, ensuring interoperability between various systems. By providing a common language and structure, ISO/IEC 7498-1 facilitates better communication and understanding among networked devices, promoting efficient data exchange.
