Open System Interconnection (OSI Model)
Although vendor-defined proprietary networking models often worked well, having an open, vendor-neutral networking model
would aid competition and reduce complexity. The International Organization for Standardization (ISO) took on the task to
create such a model, starting as early as the late 1970s, beginning work on what would become known as the Open Systems
Interconnection (OSI) networking model. ISO had a noble goal for the OSI model: to standardize data networking protocols to
allow communication between all computers across the entire planet. ISO worked toward this ambitious and noble goal, with
participants from most of the technologically developed nations on Earth participating in the process.
