  • Q: What Is a Brief History of Computer Technology?

    A: In 1822, the mathematician Charles Babbage designed the first programmable computer, which was steam powered and programmed with punch cards. However, Babbage was unable to complete the machine, which he called a difference engine, due to a lack of government funding. In 1936, Alan Turing conceived of the first electronic computing machine capable of calculating anything computable and storing programs in memory. Various prototypes were secretly built and used during World War II to decode German military radio transmissions.
