Punch card machines could not perform automatically, like later computers,
because they lacked alterable instructions built into the machine, and had limited

The Mark I, developed by Howard Aiken in 1944, was an automatic __________
computer that used punch card techniques.
The electromechanical Mark I featured electromagnetic _________________

A computer was developed during World War II to calculate the paths of new
____________________ systems for the Army.
ENIAC, the first high-speed all _________________ computer, was developed
by Eckert and Mauchley between 1939 and 1946.
ENIAC's "wire-your-own" instruction technique made it hard to _____________
for other purposes.
ENIAC was frequently out of commission, because if one of its 17,468
_____________ _______________ went out, the entire system was down.
In 1945, John Von Neuman spread the word about the stored program theory, a
set of concepts necessary for developing the __________________________.
According to the stored program theory, a computer could have a very simple
fixed physical structure and yet perform any computation without requiring
changes in __________________________.
