Difference Engine
D
Arithmometer
Explanation: 

Detailed explanation-1: -In 1834, with the Difference Engine project stalled, Babbage conceived of a new more ambitious machine, later called the Analytical Engine-a general-purpose programmable computing machine.

Detailed explanation-2: -An early prototype of the Difference Engine was built by 1822, and Babbage, with the help of the British government, started work on the full machine in 1823. It was intended to be steam-powered and fully automatic, unlike other mechanical calculating machines that required manual operation.

Detailed explanation-3: -Difference Engine, an early calculating machine, verging on being the first computer, designed and partially built during the 1820s and ‘30s by Charles Babbage.

Detailed explanation-4: -Still, the British adopted his proposed two-shilling piece, or florin, making ten florins equal to a pound sterling. Babbage never fully finished the expanded Difference Engine, which he began calling the “Analytical Engine, ” but parts of the original ran smoothly in displays and kept bringing him more attention.

Detailed explanation-5: -Difference Engine No. 1, designed to calculate and tabulate polynomial functions. The design describes a machine to calculate a series of values and print results automatically in a table. Integral to the concept of the design is a printing apparatus mechanically coupled to the calculating section and integral to it.
