A bomb may refer to any of the following:
Apple Macintosh users may encounter bomb errors when operating the computer. These error codes are part of our macOS overview. The picture is an example of how this bomb may appear.
PC users may use BOMB as slang for when the computer freezes, not allowing the user to input or get input out, usually fixed by pressing Ctrl+Alt+Del. Unlike the Apple Macintosh, when a PC crashes, you will not see the bomb. Instead, you may see a BSOD (blue screen of death).
