What does the acronym GIGO stand for?

The acronym GIGO stands for "Garbage in, garbage out." This phrase highlights the principle that the quality of output is determined by the quality of the input. In computing and data processing, if flawed or nonsensical data (garbage) is entered into a system, the resulting output will also be flawed or nonsensical. This concept is crucial for understanding the importance of accurate data entry and processing, as it underscores that systems can only produce reliable and meaningful results if they are fed with quality data. Thus, ensuring data integrity and accuracy is essential for effective information systems to function correctly.
