People who know about computers usually use the term Debug. It is used to state that there are problems in a program that need to be fixed.
According to my Computer Science teacher, back in the 1940s they used to have computers that were programmed with wires coming in and out of black boxes known back then as computers. He says that one day the people who used the computers to do simple math calculations were getting wrong answers for simple problems like 2+2. They later opened up the computers to see what was wrong with the program and they found a moth that was touching two wires, causing them to short and produce wrong answers. Since then we've been using the term "DEBUG"
