What's In A Name?

The origin of the name Mark/Space is rooted in the era of telegraph communications, railroads and morse code. Although most people think of morse code as an audio signal, it actually originated as a graphical method of communication: A pen was connected to an electromagnet device and held over a moving piece of paper. Messages were keyed in from another location which created an electrical current over copper wires to the receiving end.

When there was an electrical current present from the wires, the pen pressed down on the paper to make a mark (long or short) and released to make a space. Telegraph operators eventually got so good at morse code that they understood the messages without even reading the marks, and soon the pen and paper were removed entirely.

To this day, though, the underlying protocol for telegraph is still mark and space.
