During World War II, ballistics computing was done by women, who were hired as "computers." The term computer remained one that referred to mostly women (now seen as "operator") until 1945, after which it took on the modern definition of machinery it presently holds. [44]
However, these were not programmable and generally lacked the versatility and accuracy of modern digital computers. [34] The first modern analog computer was a tide-predicting machine, invented by Sir William Thomson (later to become Lord Kelvin) in 1872.
This machine invented the principle of the modern computer and was the birthplace of the stored program concept that almost all modern day computers use. [52] These hypothetical machines were designed to formally determine, mathematically, what can be computed, taking into account limitations on computing ability.

As an analog computer does not use discrete values, but rather continuous values, processes cannot be reliably repeated with exact equivalence, as they can with Turing machines. [58] The first modern analog computer was a tide-predicting machine, invented by Sir William Thomson, later Lord Kelvin, in 1872. It used a system of pulleys and wires ...
