Networks[1]

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 

Graphic[edit]

I use this excellent diagram from Cloudflare[4] illustration of OSI model

Standards[edit]

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