Accuracy
The similarity of a distance measured by the tablet with the actual distance. When we
specify that the accuracy of a tablet is ± .010 inches, we mean that every point in the Active
Area is within .010 inches of where it should be.

Baud Rate
Rate of speed that data flows between a host computer and the digitizer. It is the number of
bits transmitted per second. The lower the baud rate, the slower the speed.
Bit

2.) Symbol displayed on the screen marking where the next action will take effect, or
where the next character typed from the keyboard will appear.
Data Bits
Each transmission contains 7 or 8 data bits.
Data Rate
