History of Data Communication

* On 1836, American artist Samuel Morse, physicist Joseph Henry and Alfred Vail developed an electrical telegraph system. They developed a model using crude materials such as home-made batteries and old clock gears. A code was needed to transmit natural languages using the pulses the telegraph transmit. Thus paving the way for Morse to develop the Morse code.

* On 1875, a French inventor named Emil Baudot developed a code for machine coding and encoding and is suitable for transmitting 32 different code combinations. This is called the Baudot code. Two of the aforementioned 32 code combination (FIGS and LTRS) were used to change character sets.

* On 1876, Alexander Graham Bell obtained the patent rights for the first practical telephone that he developed. The first words he uttered was “Mr Watson, come here, I want you! He is also the founder of the American Telephone & Telegraph Company otherwise known as AT&T

* The teleprinter was invented in the early 1900s mainly manufactured by the Teletype Corporation which is a branch of the AT&T Company. The teleprinter utilized the Baudot code and stop/start transmission since the transmission is machine generated and decoded and must be delineated.

* Teleprinter transmission technology created the "Tape Punch" and "Tape Reader" devices. Teleprinter messages could be received on tape, then resent or broadcast to other teleprinters by using the tape reader. If there were errors in the transmission, the tape could be resent. Data messaging networks evolved, to allow individuals to communicate with each other in a digital format.

* In the 1960s, significant advances in data communications character coding resulted in the development of 8-Bit characters. In 1962, IBM created and promoted, a coding standard known as Extended Binary-Coded-Decimal Interchange Code, or EBCDIC for short. This coding scheme defined 8-bit characters, allowing up to 256 characters to be...
