GlossaryThis section explains easily terms that are used with the projector and difficult terms that are not explained in the text of this guide. For details, 
refer to other commercially available publications.
Ad hoc
A method of wireless LAN connection that communicates with wireless LAN clients without using an access point. It is not possible to 
communicate with two or more devices simultaneously.
Authentication server
A server to perform user authentication. When an authentication server is used, user information management and user authentication 
operations are unified. Also, because the authentication server often provides an advanced authentication method, it is also effective as a 
security countermeasure.
Channel
Communication speeds drop if there are too many devices performing wireless communication by using the same frequency. In this case, 
interference from other wireless LANs can be avoided by setting a different wireless channel for each wireless LAN network.
DPOF
An abbreviation of Digital Print Order Format, this is a format for recording information (photos that you want to print, number of copies, 
and so on) to print photos taken with a digital camera in recording media such as memory cards.
DV I
An abbreviation of Digital Visual Interface, this is the standard by which video signals are transmitted digitally.
DVI is the standard not only for computers, but also for digital home appliances to be able to transfer images with a resolution greater 
than DFP, and there is also an encryption function in the digital signal.
MAC address
An abbreviation of Media Access Control.The MAC address is an ID number unique to each network adaptor. A unique number is 
assigned to each network adaptor, and data is transmitted between network adaptors based on this identification.
NDIS
An abbreviation of Network Driver Interface Specification, this is the standard specification of network drivers to use network cards such 
as wireless LAN cards set by the Microsoft Company and so on. It provides communication protocols for OS, software, and drivers to 
communicate, as well as communication protocol regulations for drivers and network cards.
RADIUS Server
RADIUS is an abbreviation of Remote Authentication Dial-In User Service, this is a protocol that starts wireless LAN and is used for 
authentication by a variety of network services. A RADIUS server with an authentication server
g that uses RADIUS performs 
authentication for access to a wireless LAN access point with information such as user name and password. When a RADIUS server is 
used, user information does not need to be individually registered for each access point even when there are multiple wireless LAN access 
points, and the access point and the users can be controlled.
SVGA
A type of video signal with a resolution of 800 (horizontal) × 600 (vertical) dots that is used by IBM PC/AT-compatible computers.
SXGA
A type of video signal with a resolution of 1,280 (horizontal) × 1,024 (vertical) dots that is used by IBM PC/AT-compatible computers.
USB

VGA
A type of video signal with a resolution of 640 (horizontal) × 480 (vertical) dots that is used by IBM PC/AT-compatible computers.
Virtual display
The screen for one computer is output to multiple displays. A large virtual screen can be created by using multiple displays.
XGA
A type of video signal with a resolution of 1,024 (horizontal) × 768 (vertical) dots that is used by IBM PC/AT-compatible computers.
