The OSI model is a standard developed by ISO for designing of computer networks.

OSI stands for Open Systems Interconnection and was created by ISO, the International Standards Organization.

The OSI "reference model" divides particular networked processes into seven different layers:

Application (Layer 7)

Presentation (Layer 6)

Session (Layer 5)

Transport (Layer 4)

Network (Layer 3)

Data-Link (Layer 2) and

Physical (Layer 1)

There are at least 2 ways (mnemonics) to help you remember the layers:

1. Please Do Not Throw Sausage Pizza Away.

2. All People Seem To Need Data Processing.
