The OSI Model
This problem was addressed by the International Standards Organisation (ISO) in 1978 and the ISO Model became an international standard, agreed by all countries, in 1984.

In short, the ISO set out to achieve the following objectives:

To interconnect equipment, made by different manufacturers, through a standard interface
To integrate software and hardware, and to be portable on differing systems
Create a model which will be adhered to by all countries of the world.

They basically wanted to create an open standardised networking model that all vendors would support. Headed up by the ISO, work began on what would be known as the Open System Interconnection (OSI) networking model. It simply had one goal: to standardise data networking protocols to allow communication between all computers across the entire planet.

But this caused one more problem. How does information move between computers and applications? Well, the problem was divided into seven manageable problems or layers. Each layer soles one of the seven problems.

This set of notes will discuss the OSI Model and look each of the seven layers. It will also look at why the OSI Model with introduced as a way to set standards.
