Definition of "computer" from the Oxford Dictionaries Online: an electronic device which is capable of receiving information (data) in a particular form and of performing a sequence of operations in accordance with a predetermined but variable set of procedural instructions (program) to produce a result in the form of information or signals. a person who makes calculations, especially with a calculating machine. I suppose that would make ENIAC a computer, since the program is variable, even if only by moving lots of wires. /Jonas
