What does BSOD commonly refer to in computing?

BSOD commonly refers to the Blue Screen of Death, which is a critical error screen displayed by the Microsoft Windows operating system when it encounters a fatal system error. This type of error indicates that the operating system has reached a condition where it can no longer operate safely, often due to hardware or driver conflicts, corrupt hardware, or problems with the operating system itself. The Blue Screen provides diagnostic information that can help users and technicians troubleshoot the issue, typically displaying error codes and system information to identify the underlying cause of the problem.

This term has become widely recognized in computing and tech culture as it signifies a serious failure that affects the functionality of the computer. The other options do not accurately capture this specific context or the meaning associated with BSOD in computing.
