    9. 9. History of Computers Analytical Engine <ul><li>Ada Byron, Countess Lady Lovelace by marriage, prepared a detailed sequence of instructions for the Analytic Engine. She earned her spot in history as the first computer programmer </li></ul>
    10. 10.

History of Computers 1944 <ul><li>World War II </li></ul><ul><li>25 miles target. </li></ul><ul><li>Solving equations was </li></ul><ul><li>laborious </li></ul><ul><li>Harvard and IBM </li></ul><ul><li>Mark I computer. </li></ul><ul><li>Switches, relays, rotating shafts, and clutches. </li></ul><ul><li>Ran non-stop for 15 years </li></ul>
    13. 13. History of Computers ”Bug” <ul><li>First computer &quot;bug&quot;: a dead moth that had gotten into the Mark I and whose wings were blocking the reading of the holes in the paper tape. The word &quot;bug&quot; had been used to describe a defect since at least 1889 but Hopper is credited with coining the word &quot;debugging&quot; to describe the work to eliminate program faults. </li></ul>
    14. 14. History of Computers <ul><li>1953 Grace Hopper invented the first high-level language, &quot;Flow-matic&quot;.
