How to memorise of functions of physical layer using mnemonics

Pia Jaiswal

The functions are
Physical characterstics
Representation of bits
Data rate
Synchronisation of bits
Line configuration
Physical topology
Transmission medium

Could there be a mnemonic phrase to remember the functions.
Please suggest!!!!!:)

You need to know what happens on the physical layer... Hubs, Nics, cables etc

If we had to memorize all that, no one would pass.

I passed Net+ on the first attempt, and never used such a mnemonic. Basically, if you can touch it or get a shock from it, it's probably on the physical layer. Routers and switches being the exceptions here since they have to "think" about where to send traffic.

Hope that helps

To Remember think this:

SAP = Big Company SAP
TD = The big TD BANK
NP = Nurse Practitioner

S = Session
A = Application
P = Presentation
T = Transport
D = Data Layer
N = Network Layer
P = Physical Layer

SAP = Application Layer (Apps) }
T = Transport (TCP / UDP, etc) } Software
DNP = Network Layer (Hub, Switch, Router) } Hardware

I just made this up while studying the other day. Seem to stick.

Forgive me, I'm a little confused lol. Wouldn't it be:

A - Application
P - Presentation
S - Session
T - Transport
N - Network
D - Data
P - Physical

Or are they just mnemonics to help remember the names not the order?
