    Post How to memorise of functions of physical layer using mnemonics

    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

    SAPTDNP

    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?
