The ratio of the full-scale range(FSR) of a data converter to the smallestdifference it can resolve. DR = 2 n , where n is theresolution in bits.A gradual movement away from the definedinput/output condition over a period of time.A program that acts as the interface between ahigher level coding structure and the lower levelhardware/firmware component of a computer.Data set ready. An RS-232 modem interfacecontrol signal, which indicates that the terminal isready for transmission.Data terminal equipment. Devices acting as datasource, data sink, or both.Allows acquired data to be transferred from onboardmemory to the computer’s memory whiledata acquisition is occurring.The ability to send and receive datasimultaneously over the same communicationsline.Dynamic random access memory. See RAM.Extended binary coded decimal interchange code.An 8-bit character code used primarily in IBMequipment. The code allows for 256 different bitpatterns.Electrically erasable programmable read-onlymemory. This memory unit can be erased byapplying an electrical signal to the EEPROM andthen reprogrammed.Enhanced graphics adapter. A computer displaystandard that provides a resolution of 640 by 350pixels, a palette of 64 colors, and the ability todisplay as many as 16 colors at one time.Electronic Industries Association. Anorganization in the USA specializing in theelectrical and functional characteristics ofinterface equipment.
