No, they were not.
Absolutely, but those are called analog computers and operate very differently than the way digital computers do.Electronic analog computers long predate electronic digital computers and until the invention of the microprocessor were almost always less expensive than electronic digital computers. In some cases hybrid computers were built composed of a digital computer, an analog computer, and converter circuits so that data could be transferred back and forth between the two computing sections of the machine.The most common type of electronic analog computer was the electronic differential analyzer, but there are many other types that have been built for solving specific classes of problems (e.g. electronic harmonic analyzers, electronic finite element analyzers) via electronic analog means.
nothing yet. you are using an electronic computer.
