If you still have any questions after reading those, we'd be happy to help you out.

Data encapsulation starts at the application layers and works its way down with each layer adding its own data. This would be the Sender

Decapsulation flows the other way around...

The tech notes here are excellent and should be read before sitting any exam that the ntoes here cover.

My only complaint with the technotes here were the mnemonic for the OSI. I couldn't remember it for some reason. A friend taught me this one:

Please Do Not Throw Sausage Pizza Away

but, then i got hungry whenever i would study.

The one I have memorized is;

All People Seem To Need Data Processing...

That one is common and it truly helped me remember the seven layers of the OSI reference model...

Application
Presentation
Session
Transport
Network
Data Link (or simply Data)
Physical

what we can assume is that everybody "seems to need" something

The one I used to remember when I was studying for my network+ was:

People ----> Physical
Don't ----> Data Link
Need ----> Network
To ----> Transport
Smoke ----> Session
Pot ----> Presentation
Anymore ----> Application

Please don't take any offense to this. I just used this acronym because it was funny.
