Q:
What is USB (Universal Serial Bus)?
A:
Think of USB as 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. There are three main benefits of
USB. USB eliminates "case anxiety," the fear of removing the computer case to install
circuit board cards -- that often requires adjustment of complicated IRQ settings -- for
add-on 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 come on the market every day.
With USB, up to 127 devices can run simultaneously on one computer. USB permits "hot
plug-in." No need to shut down, plug in, reboot and run set up to install peripherals. No
need to go through the reverse process to unplug a device. Bottom line: USB transforms
today's "Plug-and-Pray" into true Plug-and-Play!
Please refer to glossary for more information about USB.
Q:
What is a USB hub ?
A:
A USB hub provides additional connections to the Universal Serial Bus. A hub's
upstream port connects a hub to the host, usually a PC. Multiple downstream ports in a
hub allows connection to another hub or device, such as a USB keyboard, camera or
printer.

Q:
What is a Liquid Crystal Display?
A:
A Liquid Crystal Display (LCD) is an optical device that is commonly used to display
ASCII characters and images on digital items such as watches, calculators, portable
game consoles, etc. LCD is the technology used for displays in notebooks and other
small computers. Like light-emitting diode and gas-plasma technologies, LCD allows
displays to be much thinner than cathode ray tube (CRT) technology. LCD consumes
much less power than LED and gas-displays because it works on the principle of
blocking light rather than emitting it.
