    14. If you have a 100GB Harddrive, how many bits are required to address each 512-byte chunk of data?

    I'm not sure about these numbers, i.e. maybe there are 1024 MB in a GB? But this is what I would do...

    512 bytes is half of a KB, 1000 KB in a MB, 1000 MB in a GB.

    So that's 2*1000*1000*100 = 200 000 000 data chunks. If each data chunk has a unique address, that's 200 000 000 addresses. How many bits do you need to count up to 200 000 000?

    We shouldn't be doing your homework for you.

    Technically there are 1024 KB in a MB and 1024 MB in a GB and 1024 GB in a TB.

    But yeah, who gives a fuck :dunno:

    100GB = 107374182400 bytes (but HD makers usually don't use 2^30 for giga)
    107374182400 bytes / 512 bytes = 209715200
    2^28= 268435456

    You should really do your own homework.
