When the first machines were created, their mechanisms were further refined by their owners as to increase their output. For instance, the first drill presses were hand cranked, which when converted to electricity increased. After a while it was found that by increasing the machines autonomy by stinging them together in an enclosure, can produce exceptionally efficient macro machines called ''factories''. | When the first machines were created, their mechanisms were further refined by their owners as to specifically increase their output.

This stepping up of machines holds true in the world of computers. The first computers (Figure 2) processed information into other kinds of information instead of using physical inputs and outputs. This, initially was done manually a human would eat some food, turn the cog on the Babbage, Difference Engine and produce new information as a productive output and waste output. A with traditional machines computer were further refined to be powered by electricity and the physical cogs were replaced with virtual cogs called algorithms. After a while, many different algorithms came together to make the modern operating system which is the equivalent to a virtual factory. | This stepping up of machines holds true in the world of computers.
