Why OSI is called Open System?

[layzie]

OSI (Open Systems Interconnection ) is a standard description or "reference model" for how messages should be transmitted between any two points in a telecommunicati on network. Its purpose is to guide product implementors so that their products will consistently work with other products. The reference model defines seven layers of functions that take place at each end of a communication. Although OSI is not always strictly adhered to in terms of keeping related functions together in a well-defined layer, many if not most products involved in telecommunicati on make an attempt to describe themselves in relation to the OSI model. It is also valuable as a single reference view of communication that furnishes everyone a common ground for education and discussion.

Why OSI is called Open System?

When we refer to OSI, we're actually referring to OSI/RM (Reference Model). In the early days of computing, like 20 yrs ago, the world was dominated by proprietary giants like IBM, DEC, Wang, Unisys, etc. ISO/OSI protocol was developed to try and sort of, OPEN up the proprietary nature of computing. Hence OPEN SYSTEM. However, the ISO/OSI protocol was never approved by the UN. TCP/IP became popular instead. As such, in schools, we learn the ISO/RM as a concept. Hope this helps.
