Will be interesting to see the marking criteria for it. I think it was worth 6 marks with 6 table cells to fill in, and seeing as there are no half-marks they should give you a mark for a one/two word answer dispite the amount of room they left.
I got, Direct Access, Direct Access, Sequential Access
and, 650MB-700MB (smaller for business card sized CD-ROMs), 1.44MB, and 10GB-40GB for the purpose of backup.
I think I also mentioned the speed and the technology used to read. Laser, Magnetic Read Head etc.
