OSI Network Model

The OSI Model divides networking into 7 basic layers. It is an easy way to understand each layer and know the functions of each.

Here are the Seven Layers of the OSI Model.

1.Physical
2.Data Link
3.Network
4.Transport
5.Session
6.Presentation
7.Application

Well, you might think, that is kind of a lot to memorize in order, well yeah it can be confusing, but here is an easy way that most people learn it.

1.Please
2.Do
3.Not
4.Throw
5.Sausage
6.Pizza
7.Away

Take the first letter of each word and it makes sence. Memorize that and it's super easy.

Next Post Will Be the TCP Model, then I will go into detail on each layer.
