 Latency
The time required for one disk revolution. The
average latency is the time required for ½ a disk
revolution. This is the average time for the head to
reach the required sector after it has been positioned
over a track.
Linear Voice Coil
Used to position the read/write heads of hard
disk drives over the data tracks. There are three main
types of design: balanced rotary positioner; non-balanced
rotary positioner; linear positioner. All three are
feedback systems and vary in the way of converting the
power of the motor into a head movement. Today, the type
used most is the rotary positioner.
Locally Administered Address
(LAA).
An address that a network administrator assigns to a
network adapter on the LAN. Administrators may assign the
adapter any address that they wish (within certain
constraints). Many administrators use the LAA to give the
adapter a meaningful address in their workplace (for
example, assigning the adapter an address that identifies
its location).
Low-Level Format (SCSI)
Formatting which takes place during the
manufacturing process. Low-level formatting checks the
integrity of the entire data recording area and divides
the recording surface into user and spare sector area.
The locations of any defective sectors are recorded to
prevent future access. Also known as media certification.
Line printer daemon (lpd).
Half of the TCP/IP remote printing protocol,this
software catches the print document that is sent from a
host computer. It is a background process that runs all
the time.
