The London Science Museum 's difference engine, the first one actually built from Babbage's design. The design has the same precision on all columns, but in calculating polynomials, the precision on the higher-order columns could be lower. A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions.
The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. [2] [3] It was first described in 1837 as the successor to Babbage's difference engine, which was a design for a simpler mechanical calculator.

Ada Lovelace. Augusta Ada King, Countess of Lovelace (née Byron; 10 December 1815 – 27 November 1852), also known as Ada Lovelace, was an English mathematician and writer chiefly known for her work on Charles Babbage 's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had ...
Allan George Bromley (1 February 1947 – 16 August 2002) was an Australian historian of computing who became a world authority on many aspects of early computing and was one of the most avid collectors of mechanical calculators. [1][2] The work on understanding Charles Babbage 's calculating engines is Allan Bromley's greatest legacy.
Note G, originally published in Sketch of The Analytical Engine Invented by Charles Babbage. Note G[a] is a computer algorithm written by Ada Lovelace that was designed to calculate Bernoulli numbers using the hypothetical analytical engine. Note G is generally agreed to be the first algorithm specifically for a computer, [1][2][3][4] and ...
A portion of Babbage's Difference Engine Trial model of a part of the Analytical Engine, built by Babbage, as displayed at the Science Museum, London The Industrial Revolution (late 18th to early 19th century) had a significant impact on the evolution of computing hardware, as the era's rapid advancements in machinery and manufacturing laid the ...
The Automatic Computing Engine (ACE) was a British early electronic serial stored-program computer design by Alan Turing. Turing completed the ambitious design in late 1945, having had experience in the years prior with the secret Colossus computer at Bletchley Park. The ACE was not built, but a smaller version, the Pilot ACE, was constructed ...
