nothing yet. you are using an electronic computer.
first generation computers were not fast and were less reliable.
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.
ENIAC, short for Electronic Numerical Integrator And Computer.
No NASA diid not exist until 1959, programable electronic digital computers were invented in the 1940s.
Early computers i.e., Electronic Numerical Video and Calculator.

SIC 3571 applies to ELECTRONIC COMPUTERS.
Actually many early computers (e.g. the Harvard Mark I) were mechanical or electromechanical, largely because people did not believe that vacuum tubes were reliable enough. However once this was proven false the fact that electronic computers were many orders of magnitude faster than the mechanical or electromechanical computers, electronic computers rapidly replaced other approaches.During the 1960s there was significant interest in building fluidics computers (i.e. hydraulic logic circuits) because they would not be disturbed by EMP or radioactivity, but this was abandoned with the introduction of microprocessors in the 1970s.
No, they were not.
because they compute maths
