Did they have computers in the 1900's?

Answer 1

no, first 'computer' was invented in 1959. There were no electronic computers in 1912. For one thing, the science of electronics as we know it had barely started. Even radio broadcasting was still in its infancy, with most "wireless" communications consisting of Morse Code broadcasts - not voice or music. There were some simple analog computers, which were mechanical devices that could be made to perform simple fixed calculations for things such as navigation and aiming military weapons. The concept of the computer as we know it, with the idea of a stored program and input/output stages actually dated back to the 19th century when a British inventor named Babbage laid out the design of a programmable mechanical computer. However the metalworking techniques of the day weren't accurate enough to allow his machine to function properly. It was not until the late 1930s that work on computers as we know them began, partly due to the need for increased calculation speeds due to progress in physics and chemistry, and significantly due to wartime needs in cryptography, aerial bombing, and signal processing. True commercial use of electronic computing didn't begin until the 1950s, and personal computers as we know them took another 20 years or so to reach the marketplace.

Answer 2

They don't have any computers in early 1900s. But they had some other machines like punched cards, electronic machines, etc to do mathematical operations.
