Serial Vs. Parallel data transmission

  1. Jan 26, 2009 #1
    1. The problem statement, all variables and given/known data
    Why is serial data transmission preferred over parallel transmission when needing to transmit data over vast distances?


    2. Relevant equations



    3. The attempt at a solution
    I think this has many different reasons...but I'm trying to pinpoint important ones.
    -I think the most obvious is that a parallel transmission needs more lines and thus cost more.
    -Another one would be cross-talk is more emminent with signals bundled close together.
    -(I'm not sure about this one) but isn't most serial schemes asynchronous while parallel is usually synchronous? a clocking signal could get tainted with noise or DC drift.

    Can you help me think of any other reasons?

    I would stick with the first reason you gave. Cost is the important reason.
