Glossary
either of these, the monitor will exit the sRGB mode and go to a color temperature setting of 6500K.
Other:
USB plug: An upstream and a downstream USB plug is provide for user's convenience.
T
TFT(thin film transistor)
Usually made from amorphous silicon (a-Si) and used as a switch to a charge storage device
located below each sub-pixel on an active matrix LCD.
U
USB or Universal Serial Bus
A smart plug for PC peripherals. USB automatically determines resources (like driver software and
bus bandwidth) required by peripherals. USB makes necessary resources available without user
intervention.
● USB eliminates "case anxiety" -- the fear of removing the computer case to install add-on
peripherals. USB also eliminates adjustment of complicated IRQ settings when installing
new peripherals.
● USB does away with "port gridlock." Without USB, PCs are normally limited to one printer,
two Com port devices (usually a mouse and modem), one Enhanced Parallel Port add-on
(scanner or video camera, for example) and a joystick. More and more peripherals for
multimedia computers arrive on the market every day. With USB, up to 127 devices can run
simultaneously on a computer.
● USB permits "hot plug-in." There's no need to shut down, plug in, reboot and run set-up to
install peripherals. And no need to go through the reverse process to unplug a device.
In short, USB transforms today's "Plug-and-Pray" into true Plug-and-Play!
Hub
A Universal Serial Bus device that provides additional connections to the Universal Serial Bus.
Hubs are a key element in the plug-and-play architecture of USB. The Figure shows a typical hub.
Hubs serve to simplify USB connectivity from the user's perspective providing low cost and
complexity.
