What is the OSI model? Memorize each of its seven layers

Learn each of the seven layers of the Open Systems Interconnection, or OSI, model with this easy mnemonic trick. The OSI Model was developed in order to help troubleshoot network problems, promote interoperability among devices, and to simplify the task of writing network protocols.

after reading this lesson for my Net+ exam I searched multiple videos for a more clear understanding of the OSI model. This helped me more than any video I previously watched. Thank you!

Some quick reference example of protocols and things in use on each layer

layer 1 - cables
layer 2 - mac addresses
layer 3 - ip addresses
layer 4 - protocols (tcp)
layer 5 - Netbios
layer 6 - ssl
layer 7 - https

For fun -
Layer 8 - the user :)

Open System Interconnection (OSI) Model - 7 Layers


Layer 1 to 7 – Please Do Not Throw Sausage Pizza Away
Layer 7 to 1 – A Penguin Said That Nobody Drinks Pepsi



Application - Layer 7
This is the layer at which applications are displayed to the end user.



Presentation - Layer 6
At this layer data is prepared for presentation between layers for e.g. data that is encrypted across a network would be decrypted at this layer for presentation to an application at the destination device.



Session - Layer 5
For two devices to transact specific functions between each other a session is required and this layer handles setting up sessions coordinating the rules for communication such as how long to wait for responses and how to terminate the session.



Transport - Layer 4
This layer coordinates the transfer of data between systems and hosts specifying such things as how much data to send and at what rate.



Network - Layer 3
This is the routing layer at which packets are forwarded from their source to their destination layer.



Data Link - Layer 2
This layer provides the direct protocol connection between two nodes on a network and handle error connection from the physical layer.



Physical - Layer 1
This includes the cable and wireless connections among devices as well as specifications of the jacks, plugs, voltages, etc.

All People Seem To Need Data Processing

[biofreezemono]

I am an information security technologies student and our teacher decided to tell about this at our 2nd week of school, in 1st grade. Lesson's name is introduction to cybersecurity but from what I understand this has more to do with networking than cybersecurity. I dont think this is the thing we're supposed to be learning at the 2nd week of our university life, but since i have no knowledge of the subject; i cannot really put my head around stuff and decide if this is the right place to start or not. Is this something you're supposed to learn at your 2nd week at university?

[seydinho]

hi can you explain me how you make this video?

This one is boring and obvious but makes sense in this context.

This is what I use to memorize all 7 layer names.
(P)eople, - (P)hysical layer
(D)ont, - (D)atalink layer
(N)eed, - (N)etwork layer
(T)o, - (T)ransport layer
(S)ee, - (S)ession layer
(P)eople, - (P)resentation layer
(A)lways. - (A)pplication layer
