I cannot find the problem with my vehicle . In the morning, at times engine starts. Once engine starts, after using vehicle for about 30 minutes, to re- start engine is difficult. Replaced throttle position sensor, water temp sensor and in tank fuel pump

Computers have wedged themselves into every facet of our lives—they are what we would use as the symbolic representation of the modern world.
But did you know that the history of computers dates back to the 1800s?
Indeed, the history and evolution of computers is quite extraordinary—and with many early computing technology innovations tied to defense contracts, much of this information were kept secret from the public for decades. In this article, we explore the development and progression of computers.
These early computers were never completed during Babbage’s lifetime, but their complete designs were preserved. Eventually, one was built in 2002.
While these early mechanical computers bore little resemblance to the computers in use today, they paved the way for a number of technologies that are used by modern computers, or were instrumental in their development. These concepts include of the idea of separating storage from processing, the logical structure of computers, and the way that data and instructions are inputted and outputted.
Other important mechanical computers are the Automatic Electrical Tabulating Machine—which was used in the U.S. Census of 1890 to handle data from more than 62 million Americans—and the first binary computer: Konrad Zuse’s Z1, which was developed in 1938 and was the precursor to the first electro-mechanical computer.
1930s: Electro-Mechanical ComputersElectro-mechanical computers generally worked with relays and/or vacuum tubes, which could be used as switches.
Some electro-mechanical computers—such as the Differential Analyzer built in 1930—used purely mechanical internals but employed electric motors to power them.
These early electro-mechanical computers were either analog or were digital—such as the Model K and the Complex Number Calculator, both produced by George Stibitz.
