How many bit code is used by Murray code for TELEPRINTER machines?
5 bit code is used by Murray code for TELEPRINTER machines.
They used the 5 bit ITA2 code and generally worked at 60 to 100 words per minute. Later teleprinters, specifically the Teletype Model 33, used ASCII code, an innovation that came into widespread use in the 1960s as computers became more widely available.
It was the predecessor to the International Telegraph Alphabet No. 2 (ITA2), the teleprinter code in use until the advent of ASCII. Each character in the alphabet is represented by a series of 5 bits, sent over a communication channel such as a telegraph wire or a radio signal.
