    Communication, control and addressing level

    I automatically thought the answer is B, but it turns out the answer is D. I'm 100% certain B is also right, but is it actually wrong?

    Would love to know why the answer isn't B.

    In multiple choice you are looking for the most correct option. So 2 options can be correct, but 1 is usually deemed as most correct by the markers.

    D is the most technically correct/specific.

    But D occurs in the application level, it even says it in Samuel Davis' book.

    iirc it happens at the CCA level.

    HSC answers > Sam Davis

    It is not impossible for the IPT HSC answers to be wrong, my class found 3-4 wrong questions back in 2014. So i'm not 100% sure.

    Checksum wont detect all errors in transmission, so it does not "ensure" this.

    It definitely reorganises data for transmission (puts into packets etc) so D is the more correct answer.
