The main difference between a diesel and a steam engine is the diesel engine is an internal combustion and the steam engine is external combustion.

In 1822, Charles Babbage conceptualized and began developing the Difference Engine which was never completed in full scale. Then in 1837, he conceptualized the Analytical Engine which his son, Henry Babbage, completed in 1910.
Babbage proposed his difference engine in 1822 and his analytical engine some years later. Both were mechanical computers (like old adding machines) Babbage built neither. It was not until recently (1991) that a working difference engine was completed.
The Difference Engine and Analytical Engine were developed by the British mathematician and inventor Charles Babbage. The Difference Engine, designed to compute polynomial functions, was conceived in the early 1820s, while the more advanced Analytical Engine, which featured concepts of programmability and data storage, was designed in the 1830s. Although neither machine was completed during Babbage's lifetime, his ideas laid the groundwork for modern computing.
Difference between Percentage of Completion method and Completed Contract method?
The Difference Engine, designed by Charles Babbage in the 19th century, was a large and heavy mechanical calculator. The completed machine was estimated to weigh around 15 tons (approximately 13,600 kilograms). Its substantial weight was due to the intricate brass and iron components required for its operation. However, only prototypes and smaller models were built during Babbage's time, as the full-scale version was never completed.
Charles Babbage designed the first mechanical calculator, known as the Difference Engine, in the early 1820s, with the initial plans created around 1822. Although he never completed a full working model of the Difference Engine during his lifetime, he continued to work on the concept, leading to the design of the more advanced Analytical Engine in the 1830s.
The Difference Engine has 256 pages.
It partly depends on what you mean by "computer", but the earliest claim is that Charles Babbage invented the first programmable computer in 1822. The machine was called a "difference engine" and it was intended to generate mathematical tables. This machine contained 25,000 parts and weighed 15 tons. Babbage followed this with a "difference engine 2" which, although well funded, was never completed. Babbage also designed a printer to go along with the computer, but this also was never completed. In 1989-1991, the London science museum made a difference engine 2 and printer from Babbage's design. Both worked perfectly.
