What term is related to the concept of input data affecting the output in a computer system?
Answer:
Accuracy
The GIGO principle, short for "Garbage In, Garbage Out," is a fundamental concept in computing. It emphasizes that the quality and accuracy of the output produced by a computer system are directly dependent on the quality and accuracy of the data inputted into it. Therefore, 'Accuracy' is the term that best represents this relationship.
