    Thanks, Helix, for answering my thread "How determine GB in use in computer?" How do I go about calculating the GB I need? I just use my PC for visiting web sites (occasionally watching a little video at newspapers and TV networks), creating and saving documents and spreadsheets, and e-mail. I have Windows XP Home.

    Also, I am confused about the 120GB "ultra hard drive"--how does that square with the 448MB RAM (I understand 1GB=10,030MB, which wouid equate to 44.7GB).

    Thanks again.

    first..its 1000 MBs = 1 GB
    ram is Volatile ....that means when you turn off the computer...its gone...a hard drive is nonVolatile so the data remains after you turn off the power...think of the hard drive as a filing cabinet...so if you want to save video or lots of music the you need a larger HD...if your not saving Video files that can be up 5 GB each then a 120 GB HD will be plenty for documents and a 1000 or so pics and still have room..

    Actually, kilobytes, megabytes, gigabytes, etc. are not even decimal figures, except for disk manufacturers. Real gigabytes are used by any operating system.

    Kilobyte: 1024 bytes
    Megabyte: 1024 * 1024 bytes (1,048,576 bytes)
    Gigabyte: 1024 * 1024 * 1024 bytes (1,073,741,824 bytes)

    This is why when you format your shiny new 120gigabyte disk, you find it only has about 111.75 gigabytes when Windows finishes. :)

    I know ...tried to keep it simple though considering he says"(I understand 1GB=10,030MB, which wouid equate to 44.7GB)."
