Random Access Memory. an integrated circuit memory chip that
RAM
allows information to be stored and retrieved by a
microprocessor or controller. The information can be stored or
accessed in any order, and all storage locations are equally
accessible.
The ability to directly locate any piece of data without
random access
having to read everything in memory or on disk.
A mode of operation that has the computer read back
read after write
each data block immediately after it is written on the tape,
checking that the data read back is the same as recorded.
The mechanism by which data is recorded onto magnetic
read/write head
media in a tape drive system. See read after write.
Reed-Solomon error correction
research done by Irving reed and Gustave Solomon at MIT's
lincoln Laboratory in the 1960s. First used to check the accuracy
of data received from the Voyager spacecraft.
To replace data on the hard drive with data obtained from
restore
another media device.
Restrictions on Hazardous Substances is an EU directive that
RoHS
restricts, and in some cases bans, the use of certain compounds in
the manufacture of electronic equipment. RoHS mandates that
new electrical and electronic equipment put on the market does
not contain lead, mercury, cadmium, hexavalent chromium,
poly-brominated biphenyls (PBB), or poly-brominated diphenyl
ethers (PBDE).
Read Only Memory. Integrated circuit chip containing programs
ROM
and data that can be accessed and read but cannot be modified.
Storage Area Network.
SAN
Refers to the capability provided by the DLT tape drive
scalability
family to read tapes from previous generations of drives. Allows
users to upgrade to a faster, higher capacity DLT drive, yet still
be able to read tape recorded on an older system. The term also
refers to the ability of DLT tape library systems to be upgraded
with a higher performance DLT drive and thus provide more
