How to memorise of functions of physical layer using mnemonics
The functions are
Representation of bits
Synchronisation of bits
Could there be a mnemonic phrase to remember the functions.
CISSP, CySA+, Security+, Network+ and others
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.
CISSP, CySA+, Security+, Network+ and others |
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?
