Super Digital Linear Tape.
SDLT
The movement of a read/write head to a specific data track.
seek
Found in all DLT tape drives. Tiny ridges on either
self-cleaning head
side of the DLT drive read/write head continuously wipe the
tape clean as it passes over the head. This is why there is no
periodic cleaning prescribed for DLT tape drives.
A powerful computer system with a large capacity tape or hard
server
disk drive that serves the information access and communication
needs of multiple users.
T
he length of time that media can be stored without losing its
shelf life
magnetic strength. For Super DLTtape II media, this period is 30
years or more.
A rating, expressed in Gs which stands for multiples of
shock rating
gravity, of how much shock a tape drive can sustain without
damage. Operating and non-operating shock levels are usually
specified separately.

Simple Mail Transfer Protocol. An e-mail protocol on the Internet
SMTP

Simple Network Management Protocol. A protocol that monitors
SNMP
and controls a network.
Simple Network Time Protocol. SNTP is based on NTP, the
SNTP
Network Time Protocol, an industry standard way for computers
to synchronize their time to an external reference standard. NTP
and SNTP are fully interoperable. Each consists of a client, for
example the SuperLoader, which obtains the current time (in
UTC) from either an SNTP server or an NTP one. SNTP and NTP
are in wide use on the Internet. NTP is specified by RFC1305.
SNTP is specified by RFC2030.
A faulty data reading that does not recur if the same data is
soft error
reread from the disk or corrected by ECC. Usually caused by
power fluctuations or noise spikes.
S
tatic RAM. A memory chip that requires power to hold its
