:: The longest a process has been waiting on a mainframe would be Ada Lovelace's program to calculate Bernoulli numbers on the Analytical Engine.

Charles Babbage ( 1791-1871 ) is credited with the design of the modern computer, which he called a " difference and analytical engine ."
33.
Before the advent of electronics, mechanical computers, like the Analytical Engine in 1837, were designed to provide routine mathematical calculation and simple decision-making capabilities.
34.
The analytical engine had expandable memory, an arithmetic unit, and logic processing capabilities able to interpret a programming language with loops and conditional branching.
35.
They figure out the best-valued ticket by using an analytical engine that compares a seat's distance from the action to the price of the ticket.
36.
The analytical engine would have had a memory capacity of less than 1 kilobyte of memory and a clock speed of less than 10 Hertz.
37.
Meanwhile, Babbage's attention had moved on to developing an analytical engine, further undermining the government s confidence in the eventual success of the difference engine.
38.
:Ada Lovelace's algorithm for calculating Bernoulli numbers on the Analytical Engine is often described as the first computer program-see Ada lovelace # First computer program.
39.
Charles Babbage's analytical engine ( 1830s ) would have been the first Turing-complete machine if it had been built at the time it was designed.
40.
The Mark I also computed and printed mathematical tables, which had been the initial goal of British inventor Charles Babbage for his " analytical engine ".
