Computer networking has many layers (as you will learn). This guide contains some resources that you can use to help you master some of those layers.

Books

There are a few books in the NSCC Library covering networking

OSI Model

Here are a couple of mnemonic devices to help you remember the layers of the OSI model

Please                  Physical - layer 1

Do                        Data - layer 2

Not                       Network - layer 3

Throw                  Transport - layer 4

Sausage              Session - layer 5

Pizza                   Presentation - layer 6

Away                  Application - layer 7

 

Another mnemonic you might hear is, Please Do Not Touch Steve's Pet Alligator.

If you want to work backwards and start with the Application layer, you can use the following mnemonics:

All People Seem To Need Data Processing

At Present, Some Teachers Need Dr. Phil
