TKIP Abbreviation for Temporal Key Integrity Protocol. This is an encoding method used for WPAg . The encryption key is
renewed after a certain period of time to make it harder to break the encryption code.
Tracking The signals output from computers have a specific frequency. If the projector frequency does not match this frequency, the
resulting images will not be of a good quality. The process of matching the frequency of these signals (the number of crests in
the signal) is called "tracking". If tracking is not carried out correctly, wide vertical stripes will appear in the projected images.
Trap IP address An IP addressg for the destination computer when SNMP reports that a problem has occurred.
USB An abbreviation for Universal Serial Bus. USB is an interface for connecting personal computers to peripheral devices which
only support relatively low data transmission speeds.
UXGA A type of video signal with a resolution of 1600 (horizontal) × 1200 (vertical) dots which is used by IBM PC/AT-compatible
computers.
VGA A type of video signal with a resolution of 640 (horizontal) × 480 (vertical) dots which is used by IBM PC/AT-compatible
computers.
WEP This is an abbreviation of Wired Equivalent Privacy. This is a security method which encrypts data during transmission.
Data communication cannot be performed unless the sending and receiving machines are registered with the same encryption
key by the WEP.
WPA Abbreviation for Wi-Fi Protected Access. This is an encryption standard that improves security which is a weak point of
WEPg . TKIPg is used as the encryption method.
XGA A type of video signal with a resolution of 1024 (horizontal) × 768 (vertical) dots which is used by IBM PC/AT-compatible
computers.
