The language before the hardware
English mathematician George Boole introduced a newly devised algebraic language built on Leibniz work. His “Boolean algebra” was actually a system of logic, with mathematical equations used to represent statements in logic -
considering the first analog computer
A tide-predicting machine, invented by Scotch-Irish mathematician, physicist and engineer Sir William Thomson in 1872, was considered the first modern analog computer. -
Turing machine was invented
English mathematician Alan Turing published a paper called titled "On computable numbers, with an application to the Entscheidungsproblem," which outlines how a theoretical device called a “Turing machine” can be used to carry out any conceivable mathematical computation by executing instructions. In theory, the machine would have limitless memory, read data, write results and a stored program of instructions. -
the first programmable was made
Konrad Zuse who would go on to build the world’s first programmable computer.Unveiled in 1941, the Z3 was faster, more reliable and better able to perform complicated calculations. But the big difference was that the instructions were stored on external tape, allowing it function as a fully operational program-controlled system. -
point- contact transistors were made
Point-contact transistors, like vacuum tubes, transistors amplify electrical current and can be used as switches. But more importantly, they were much smaller (about the size of a pill), more reliable and used much less power overall. The co-inventors John Bardeen, Walter Brattain, and William Shockley would eventually be awarded the Nobel Prize in physics -
the first computer to run a stored program based on the Von Neumann architecture.
Nicknamed “Baby,” the Manchester Machine was a experimental computer and served as the predecessor to the Manchester Mark I. The EDVAC, the computer design for which Von Neumann’s report was originally intended. It wasn't completed til 1949
