Answer:
<h3>
The Open Systems Interconnection Model (OSI)</h3>
Explanation:
OSI Model was given birth by the International Organization for Standardization in 1978. It is a conceptual framework that defines the roles of a networking or telecommunication system. The idea is to use layers to visually describe what is happening in a particular networking system. OSI are fragmented further into seven sub components. The model functions in a hierarchy in which each layer has been assigned its own role and once the task is completed it is passed onto the next layer. These seven layers are divided in two main categories known as hot layers and media layers. Hot layer include application, presentation, session and transport layer, whereas media comprises of network layer, data link and physical layer. Today, OSI is so popular that many protocols are developed on its format.
