Please Do Not Touch Steve’s Pet Alligator!!
The Open Systems Interconnection model (OSI model) is a conceptual model that characterizes and standardizes the communication functions of a network [2]. The Open Systems Interconnection (OSI) model is a conceptual model created by the International Organization for Standardization which enables diverse communication systems to communicate using standard protocols. In plain English, the OSI provides a standard for different computer systems to be able to communicate with each other.
The OSI model can be seen as a universal language for computer networking. It’s based on the concept of splitting up a communication system into seven abstract layers, each one stacked upon the last.[3]
There are two things you need to do here: 1. simply state two layers (just their names) 2. you MUST be able to describe how communication is broken down into layers

- Describe how communication over networks is broken down into different layers.
- List the stages in the OSI model
