E
ECC. Acronym for Error Correction Code. The incorporation of
extra parity bits in transmitted data in order to detect errors that
can be corrected by the controller.
EDC. Acronym for Error Detection Code. DLTtape drives include
a 16-bit EDC with every 4KB of user data. The EDC helps the
drive detect and recover any errors that may occur.
EEPROM. Acronym for electronically-erasable programmable read
only memory. An integrated circuit memory chip that can store
programs and data in a non-volatile state. These devices, which are
used to store firmware in DLTtape drives, can be erased and
reprogrammed with new data.
Encoding. The protocol by which particular data patterns are
changed prior to being written on the tape surface as a pattern of
On and Off or 1 and 0 signals.
External Drive. A drive mounted in an enclosure, separate from
the computer system enclosure, with its own power supply and
fan, and connected to the system by a cable.
Extranet. The connection of two or more Intranets over the
Internet. This allows the privacy of an Intranet with the global
connectivity of the Internet.
Erase. The removal of data from a piece of media.
Error. A message that occurs when there is a loss of ability to
interpret recorded data. Usually due to magnetic issues or defects
in or on the media.
Error Correction Code. See ECC.
Error Detection Code. See EDC.
