DVD
Digital versatile disc or digital video disc. A type of CD-ROM
that holds a minimum of 4.7 GB, enough for a full-length
movie. The DVD specification supports disks with capacities
of from 4.7 GB to 17 GB and access rates of 600 Kbps to
1.3 Mbps. One of the best features of DVD drives is that they
are backward-compatible with CD-ROM disks. This means
that DVD players can play old CD-ROMs, CD-I disks, and
video CDs, as well as new DVD-ROMs. Newer DVD players
can also read CD-R disks. DVD uses MPEG-2 to compress
video data. See MPEG.
E
ECC memory
Error Checking and Correcting memory. Advanced type of
memory that can find and correct certain types of single-bit
memory errors, providing greater data integrity. Advanced
ECC can correct some double-bit errors.
