    Is there someone who can help with these, and other, computerese? Is there some site with definitions. I'm trying to decide what to order for my new computer.

    CD Rom is a standard disc reader. It will read the discs that install programs, music cd's, etc. A DVD RW is a drive that you can use to create DVD's. The RW means that it can READ and WRITE DVD's. So the same holds true to a CD-RW. It is a disc drive that can READ and WRITE CD's.

    DVD-ROM means that it will simply read or play DVD's but not write or burn to a blank DVD disc

    Most drives now I think are standard CDRW which means you can "burn" or transfer your music files, regular files to a disc.

    DVD discs hold more information I think they are like 4gig. WHile CD's are only 700mb.

    A DVDRW will only write to DVD discs and A CDR/W will only write to CD's.

    Hope that helps. I use CNET.com for electronic purchases and for other info.

    CD = Compact Disc
    CD-ROM = Compact disc read only memory
    CD-R = compact disc recordable
    CD-RW = compact disc rewriteable

    DVD = Digital Versatile Disc
    DVD-ROM = DVD read only memory (like a pre-recorded movie DVD)
    DVD-R, DVD+R = recordable DVDs, + and - are two different technologies but both are generally supported by current drives
    DVD-RW, DVD+RW = rewriteable DVDs, also both generally supported
    DVD+R DL = dual-layer recordable DVD, about double the capacity of non-dual-layer

    The optical drives you can buy will state what they'll read and record, while also giving you a speed (given in xX, e.g. 16X DVD+R). This refers to the multiple of the original base speed (which was 1X, and in the case of DVD+R, was 1,385,000 bytes per second).

    If they list a machine with a DVD-ROM, will I also be able to use discs such as Turbo Tax or do I need an additional CD-ROM or CD-RW (the latter to burn some discs)?

    Computer DVD-ROM drives can all read CDs. If it isn't explicitly stated as also being a CD-R/W drive, all it can do is read DVDs and CDs. You'd need a CD R/W or DVD-+RW. DVD writers can also write CDs.
