A piece of equipment that accepts data for transmission to (input) and
from (output) the system. For example, a terminal.
I/O

LAT
Local area transport. The LAT is a communications protocol that
implements terminal emulation over an Ethernet local area network.
Terminals are normally connected to terminal servers, which send
messages containing terminal data to host systems. The host systems
view the remote terminal as if it was locally connected to the host.
LED
Light-emitting diode. LEDs are used as indicators on the system
enclosure.
link
A communications path between two nodes. A physical link is the
electrical connection between two nodes. A logical link implies that two
nodes are able to communicate whether or not they have a direct physical
link.
load
To copy software (usually from a peripheral device) to memory. To
physically place a disk in a disk drive or a tape in a tape drive.
load device
The drive that holds the distribution media during software installation.
Local Area Network (LAN)
A high-speed communications network that covers a limited geographical
area, such as a section of a building, an entire building, or a cluster of
buildings. It is a privately owned communication network whose speed is
upward of 1 megabit/second.
logical link
Two nodes are able to communicate by means of software whether or not
they have a direct physical link.
