What is OSI Model

Why do we need the OSI Model?

To address the problem of networks increasing in size and in number, the International Organization for Standardization (ISO) researched many network schemes and recognized that there was a need to create a network model that would help network builders implement networks that could communicate and work together and therefore, released the OSI reference model in 1984.

Don’t Get Confused.

ISO - International Organization for Standardization

OSI - Open System Interconnection

IOS -  Internetwork Operating System

The ISO created the OSI to make the IOS more efficient.  The “ISO” acronym is correct as shown.  

To avoid confusion, some people say “International Standard Organization.”
