    Device Manager – a Windows utility that allows you to access the properties of the computer’s hardware devices such as network adapters, modems, and disk drives.

    Digital Media – pictures from a digital camera, downloaded music and movies, and similar data that is stored on a computer for the purpose of archiving, sharing, or viewing.

    Digital Subscriber Line (DSL) – a popular method for moving data over phone lines to access the Internet. DSL requires a DSL modem and monthly subscription to a DSL provider.

    Disk Defragmenter – a Windows utility that scans the files on the hard disk and reunites files that are “fragmented”. A file is fragmented when parts of it are stored on various areas of the hard drive. Defragmenting allows the disk to work more efficiently and produce results faster.
