1.Explain how are OSI and ISO related to each other?

The OSI (Open Systems Interconnection) model and ISO (International Organization for Standardization) are related to each other in the context of computer networking and telecommunications. Let's explore their relationship:

OSI Model:

    The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven distinct layers. It was developed in the late 1970s by the International Organization for Standardization (ISO) in collaboration with the International Telegraph and Telephone Consultative Committee (CCITT, now ITU-T). The OSI model aims to facilitate interoperability and communication between different systems, allowing them to exchange data and information seamlessly.

ISO:

    ISO (International Organization for Standardization) is an international standard-setting body that develops and publishes standards for various industries, including technology and telecommunications. It is a non-governmental organization with a membership of national standardization bodies from different countries. ISO's mission is to promote global standardization to simplify processes, enhance efficiency, and foster international trade and cooperation.

The Relationship:
The OSI model and ISO are closely related in the following ways:

  1.     Development: The OSI model was developed by ISO in partnership with ITU-T, emphasizing the importance of international standardization in the field of networking and data communication.
  2.     Reference Model: The OSI model is often referred to as the ISO/OSI model, emphasizing its origin from the International Organization for Standardization.
  3.     Standardization: ISO plays a significant role in establishing standards for networking and telecommunications technologies. The OSI model is one such standard developed by ISO to guide the design and implementation of network protocols and communication interfaces.
  4.     Layered Architecture: The OSI model's layered architecture provides a clear and comprehensive framework for understanding network communication processes. Each layer performs specific functions, and the model ensures that these functions are logically separated, promoting modularity and ease of maintenance.
  5.     International Adoption: As ISO is an international organization, the OSI model gained widespread international recognition and adoption as a foundational reference model for networking. It helped foster a common language and understanding of networking concepts across different countries and organizations.
  6.     Influence on Other Protocols: The OSI model has also influenced the development of other networking protocols and architectures, even if they do not strictly adhere to its seven-layer structure.


Despite its significant contribution, it's important to note that the OSI model is mainly used as a teaching and conceptual tool rather than a practical implementation. In practice, the TCP/IP model (Transmission Control Protocol/Internet Protocol) is more commonly used for actual network communication, but the principles and concepts laid out by the OSI model remain relevant and influential in networking discussions and education.
