1

Difference Engine

created by Charles Babbage, mechanical device that could approximate polynomials

2

Analytical Engine

created by Charles Babbage, idea came to light during creation of Difference Engine, a general purpose computer not just for computations that could be given data and run operations in sequence, automatically and included memory and a primitive printer

3

Charles Babbage

father of computing, invented Analytical Engine and Difference Engine

4

Step Reckoner

created by Leibniz, mechanical set of gears and knobs that could perform operations using gears in an automated way

5

Range Tables

military tables of computation that gave optimal angle for cannons/artillery given model of cannon, weather, and distance

6

Ada Lovelace

considered world's first programmer

7

Tabulating Machine

Herman Hollerith created, electro-mechanical machine that coupled mechanical gears with electrically powered components

8

International Business Machines Corporation (IBM)

merged company of Tabulating Machine Co. whose business was electro-mechanical machines intended for business computations

9

Harvard Mark I

largest electro-mechanical computer, used to run simulations for Manhattan Project

10

Mechanical Relays

electrically controlled mechanical switches (control wire determines if a circuit is opened or closed)

11

Triode Vacuum Tubes

replaced mechanical relays, vacuum tube which housed 2 electrodes and a control wire which either permitted or denied the flow of electrons between the electrodes

12

Diode

electronic component that permits 1-way flow of current

13

Colossus Mark I

first largest use of vacuum tubes in computing and first programmable electronic computer (used plug boards for programming)

14

ENIAC

first general purpose programmable, electronic computer
