I  Concepts & Terms Required - Chapter 0010
  • The ISO (International Organization for Standards)

  • The OSI (Open Systems Interconnect) reference model

  • The IEEE has its own set of networking standards

  • Understand the theory of the OSI (Open System Interconnect) model, and know the purpose of each of the OSI Layers (All People Seem to Need Data Processing)

  • The OSI model is a theoretical framework that defines how to accomplish network communications.

  • The ISO (International Organization for Standards) comprises a global team effort to provide interoperability across different countries and vendors. In February 1980, the group began the OSI (Open Systems Interconnect) reference model. This gave each vendor a standard to follow so that different products would actually work together.

  • IEEE (Institute of Electrical and Electronic Engineers) standards

  • The IEEE has its own set of networking standards, the 802.x series, which describe physical characteristics of different types of networks, such as signaling mechanism, physical cabling, and internetwork communication mechanisms.
