cell. The electrical field in the cells is supported by thin film transistors.
Touchpad
The Touchpad is used in many programs (with mouse control) as an input device
for cursor control and menu operation. The Touchpad works with touch-sensitive
sensors. The cursor can be moved over the screen with the touch of a finger.
U
USB
Acronym for universal serial bus. A serial bus with a data transfer rate of
12 megabits per second (Mbps) for connecting peripherals to a microcomputer.
USB can connect up to 127 peripherals, such as external CD-ROM drives,
printers, modems, mice, and keyboards, to the system through a single,
general-purpose port. This is accomplished by daisy chaining peripherals together.
USB is designed to support the ability to automatically add and configure new
devices and the ability to add such devices without having to shut down and restart
the system (hot plugging).
User Interface
The software-controlled menus and screens on the monitor through which the user
communicates with the program.
