data, but no data transfer occurs.
|
|
WAN
|
Wide area network. A communications network that connects
devices over wide geographically separated areas, usually
encompassing different metropolitan areas. Such networks require
public rights-of-way and operate over long distances. Large
network formed by bridging smaller LANs or using dialup lines.
WANs can even span the globe.

Warm-up Time
|
The time taken after switching on for a printer to achieve
a state where it is ready to print. The warm-up time is normally
dictated by the time taken to heat up the fuser to its operating
temperature.
|
|
Wavelength
|
The distance that an electromagnetic wave travels in one
complete cycle.
|
|
Web Access APIs
|
Web Access APIs are API's that can be implemented by HAVi
devices to enable any HAVi device in the home (such as PCs
or internet-enabled TVs) to have access to the Internet, without
requiring the device to have an IP stack itself. Through these
APIs, the Internet protocols such as HTTP and FTP are encapsulated
and delivered to these HAVi devices.

Wireless
|
Communications that take place without the use of interconnecting
wires or cables, using radio waves, microwave, or infrared.
The term refers to a broad range of technologies that provide
mobile communications for university, home or office, and
"in-building wireless" for extended mobility around the work
area, campus, or business complex. It is also includes "cellular"
communication used for in- or out-of-building mobility services.
|
|
Wireless Ethernet
|
While "Ethernet" is a wired system by definition, wireless
Ethernet describes for CSMA/CA wireless LAN's, since their
operation has a great deal in common and they are typically
integrated easily.
|
|
Wireless LAN
|
A wireless local area network (LAN) is a flexible-data communications
system implemented as an extension to or as an alternative
for, a wired LAN. Using radio frequency (RF) technology, wireless
LANs transmit and receive data over the air, minimizing the
need for wired connections. Thus, wireless LANs combine data
connectivity with user mobility. A short range computer to
computer wireless data communications network.
|
|
Wireless Network Interface Card (NIC)
|
The wireless-network interface card that typically uses DSSS
physical layer and CSMA/CA medium access control.
|
|
Wireless Node
|

WPS
|
Windows Print System: the scheme supported by Windows 95
in which the operating system spools data from an application
in Enhanced Metafile Format (EMF), instead of raw printer
data. The spooler interprets the data in the background and
then passes appropriate commands to the printer. Like with
GDI, all the processing is done on the PC.
