The OSI model is called the Open System Interconnection model because it was developed to promote open communication standards and enable different systems to interoperate seamlessly. It provides a framework for networking protocols to communicate across different hardware and software platforms, facilitating communication between open systems.
Open Systems Interconnection (usually abbreviated to OSI) was an effort to standardize networking that was started in 1982 by the International Organization for Standardization (ISO), along with the ITU-T.It is called Open System because it was intended to be used by all vendors. At that time most network vendors had proprietary protocols that were meant to work only with their software and hardware. This caused many vendors to support multiple types of hardware and software which was complicated, expensive and wasteful.The OSI standard was meant to improve networking for everybody and was open in that it applied to everyone equally.
The OSI (Open Systems Interconnect) 7-layer model is based, in-part, on standards published by the IEEE (Institute of Electrical and Electronics Engineers). For example, IEEE standard 802.3 describes Ethernet. In the OSI model, the 802.3 standard exists at layers 1 and 2. ANSWER IEEE is a standards organization to which many hardware and software suppliers both contribute to and agree to use 'standardized' techniques. Ethernet is but only ONE of the many standards, and the OSI is only one of the usage standards.
there are many layers
it has 7 layers!!
