TCP/IP
Transmission Control Protocol/Internet Protocol. A
communications protocol which ensures that the total amount of bytes
sent is received correctly, and also provides the routing information.
thin film A type of coating allowing very thin layers of magnetic material
used on tape drive read/write heads. Media with thin film surfaces can
store greater amounts of data.
track A linear or angled pattern of data written on a tape surface. DLT
tape drives write information on multiple tracks simultaneously.
track-to-track seek time The time required for the read/write heads to
move to an adjacent track.
transfer rate The rate at which the drive sends and receives data from the
controller. Usually measured in megabytes per second. A DLT 7000
drive, for example, has a native transfer rate of 5 MB/s.
U
unformatted capacity The total number of usable bytes on the media,
including the space that will be required later to record location,
boundary definitions, and timing information. See also formatted
capacity.
V
volume The quantity of information written on a piece of media.
Typically measured in megabytes or gigabytes.
W
Write Once, Read Many (WORM) An optical disk technology that allows
the drive to store and read back data but prevents the drive from erasing
information once it has been written.
write-protected Files or media that cannot be changed. user write-
protection when you want to protect data from being changed or
destroyed. To write-protect most tape cartridges, slide the write-protect
tab to the “locked” position.
Z
ZIF Zero Insertion Force. A type of socket or connector allowing a
computer chip or bar code reader to be inserted or removed with no
stress applied to either the chip or bar code reader and its respective
socket.
