1. Of a program, to run with no indication of progress and perhaps without guaraNTee of ever finishing especially said of programs thought to be executing a tight loop of code. A program that is buzzing appears to be catatonic, but never gets out of catatonia, while a buzzing loop may eveNTually end of its own accord. "The program buzzes for about 10 seconds trying to sort all the names iNTo order." See spin see also grovel. 2. [ETA Systems] To test a wire or priNTed circuit trace for coNTinuity by applying an AC rather than DC signal. Some wire faults will pass DC tests but fail a buzz test. 3. To process an array or list in sequence, doing the same thing to each elemeNT. "This loop buzzes through the tz array looking for a terminator type." [Jargon File]
