The OSI model is a conceptual tool used to discuss and describe network functions. The use of a standard reference model is essential to communicating ideas as well as creating new technologies. It is a good idea to be familiar with the OSI model, the features assigned to each layer, and examples of common protocols or technologies associated with the OSI layers.

Read moreThe OSI model has been the de facto reference model for networking protocols since the mid-1990s. The OSI model is formally known as Open Systems Interconnection (OSI) model ISO/IEC 7498-1. International Organization for Standardization (ISO) is a global standards-settings group comprised of members from various national standards groups. International Electrotechnical Commission (IEC) is another global standards-settings group that focuses on electrical, electronic, and related technologies. The IEC works closely with ISO and other groups to establish standards for computers, networking, and communications. The OSI model is a conceptual model rather than a technical specification. This means it is used to discuss, describe, compare, and contrast actual technologies rather than directly mandating elements of technology.
