- OSI Reference Model – Published by: Kakanyero Robson Jimmy | Skytech256 Network Reference Models A computer network connects two or more devices together to share information and services. Multiple networks connected together form an internetwork . Internetworking present challenges - interoperating between products from different manufacturers requires consistent standards. Network reference models were developed to address these challenges. A network reference model serves as a blueprint, detailing how communication between network devices should occur. The two most recognized network reference models are: • The Open Systems Interconnection (OSI) model • The Department of Defense (DoD) model Without the framework that network models provide, all network hardware and software would have been proprietary. Organizations would have been locked into a single vendor’s equipment, and global networks like the Internet would have been impractical, if not impossible.
