Black boxes were devices which, when attached to home phones, allowed all incoming calls to be received without charge to the caller. [1] The black box (as distinguished from blue boxes and red boxes) was a small electronic circuit, usually a resistor or zener diode in series with the line. It relied on (now-obsolete) telephone exchanges ...
A phreaking box is a device used by phone phreaks to perform various functions normally reserved for operators and other telephone company employees. Most phreaking boxes are named after colors, due to folklore surrounding the earliest boxes which suggested that the first ones of each kind were housed in a box or casing of that color.
The term "black box" is used because the actual program being executed is not examined. In computing in general, a black box program is one where the user cannot see the inner workings (perhaps because it is a closed source program) or one which has no side effects and the function of which need not be examined, a routine suitable for re-use.
The Deutsch–Jozsa problem is specifically designed to be easy for a quantum algorithm and hard for any deterministic classical algorithm. It is a black box problem that can be solved efficiently by a quantum computer with no error, whereas a deterministic classical computer would need an exponential number of queries to the black box to solve ...
It can be seen on iOS 7, and also when a white iPhone 5 or later or a white 5th generation iPod Touch screen freezes. Everything on the screen but the Apple logo turns white. [7] A Yellow Screen of Death occurs when an ASP.NET web app finds a problem and crashes. [8] [self-published source?]
When executed, a variable, s, is set to point to the string's location, and an attempt is made to write an H character through the variable into the memory, causing a segmentation fault. Compiling such a program with a compiler that does not check for the assignment of read-only locations at compile time, and running it on a Unix-like operating ...
