Meaning of GIGO in English

GIGO

Stands for "Garbage In, Garbage Out," (not for Gigobyte, considering the word is Gigabyte). It basically means that if invalid data is entered in a computer program, the resulting output will also be invalid. So if a program asked for a character and you decided to be funny and enter "3.14159", there's a good chance the results you get back would be pretty messed up, or "garbage". Because people aren't always smart enough to enter valid data, programmers have to take excessive mesaures to protect their programs from GIGO-type errors.
