Glossary 311
USB Universal Serial Bus. An external peripheral interface standard
for communication between computer and external peripherals
over an inexpensive cable using biserial transmission. USB
works at 12 Mbps with specific consideration for low-cost
peripherals. USB cables can be up to 5 meters long.
Virtual Port Incoming Telnet and rlogin connections are not associated with
a physical port. Instead, they are associated with a virtual port,
port 0, which serves for the duration of the connection. Each
virtual port is created with a default set of characteristics. The
Define Port commands can be used to customize a virtual port
during the Telnet/Rlogin session; however, these
customizations can not be saved. The port reverts to the default
set of characteristics when the session is closed.
WAN Wide Area Network. A data-communications system covering a
large geographic area, usually digital circuits having moderate
to high data rates (e.g., 56 to 64 kbps up to 1.5 to 2 Mbps).
WBT Windows-based Terminal. A thin-client device that connects to a
Citrix WinFrame or MetaFrame server to provide application
access. The key differentiator of a WBT from other type devices
is that all the application execution occurs on the server. There
is no downloading or local processing of applications at the
client.
WinFrame A multi-user Windows application server, based on Windows
NT, developed under license from Microsoft. This application
was developed by Citrix Systems, Inc.
WINS Windows Internet Naming Service. WINS allows machines to
dynamically register their name-to-address mappings. WINS is
also a flat name space without the concept of hierarchy and
requires each WINS server to maintain a complete database of
entries through replication.

control, instructing serial devices to start transmission (X-ON)
and stop transmission (X-OFF).
