- In the early 1840s Charles Babbage proposed a machine called the Analytical Engine. It was only a proposal, no actual machine was built, but one inventive woman by the name of Ada Lovelace decided to write an article that provided detailed instructions on how to represent Bernoulli numbers, a recursive equation based in number theory on the Analytical Engine. This article is considered to be the very first computer program. Since then the devices that can be programmed went from theoretical to physical, manual to automatic, analog to digital. With each evolutionary step the way we program computers needed to evolve as well. With the birth of main frame computers, data processing required instructions to be sent to the machine and interpret the instructions from the programmer. This was then applied to data to organize and analyze it. Instructions were entered through a keyboard but without a monitor, so everything was done through printouts on paper. If you look carefully at text…
