What is GIGO an acronym of?

Answer:
GIGO is an old computer programming acronym standing for "Garbage in, garbage out"

Originally it was an answer for the implied (or stated) question of whether or not computers were capable of making mistakes. If a programmer or data entry person supplies "garbage" or invalid data as input to the computer program, then we can expect to receive "garbage" or erroneous output in return.
