    i can't believe you actually posted all your questions on the post!!!! i honestly think you should find this out yourself to learn.... sorry brother.

    Yeah... seriously... you should do the work yourself.

    How do you expect to learn it?

    Nobody will be there to help u take the tests or the certs... so do yourself a favor... whatever you don't know... start reading.

    If its the end of the year and you're having this much trouble with it... you may want to think about taking the course again.

    I know the material can be dry... but its essential.

    If you can get some hands on... you'd be much better off too.

    4 From the following list, what is the correct order of data encapsulation? 1. Segments2. Bits3. Packets4. Frames

    1) 1-3-4-2
    2) 2-1-3-4
    3) 2-3-4-1
    4) 3-1-2-4

    OK... I will try to help you out to get the answer on this one... For starters check out the OSI model... the answer will be there... You have information that needs to be sent from your computer to another...

    SO you have this message that not has to be broken up into pieces... It probably cant send the whole thing at once so it has to break things up...

    Next you have to pakage the info to prep them for transfer... This one you can look at the OSI model and see what hapens next... It is going to have something to do with IP...

    Then it has to pachage it again adding more header info... this will be the next layer down in the OSI model...

    Lastly it has to be put into 1's and 0's for the actual wire transfer...

    Hope this helps...
