Question

In the 1940s, computers were programmed using punch cards, or pieces of paper that had holes in them that represented binary code. If a mistake was made using this type of primitive programming, which of the following BEST describes what would need to be done to correct the problem?

A.
The entire program of punch cards had to be re-punched.

B.
The entire program of punch cards had to be loaded again and started over.

C.
The entire program needed to be rewritten and a different set of punch cards were used.

D.
The entire program could be fixed by adding or removing a card for the existing stack of papers.

Answer 1

If a mistake was made using punch cards to program computers in the 1940s, the entire program of punch cards had to be re-punched to correct the problem. This was because punch cards were the primary means of input for the computer, and any changes or corrections to the program had to be physically made by punching new cards or modifying existing ones. Once the program was re-punched correctly, it could be loaded into the computer and executed.
