Explain the significance of "dead beef"
Whatever you do don’t tell them its because its dead, this isn’t the right answer even though it seems obvious. The truth of the matter is that dead beef is a coding term.
It includes hexadecimal values and was used in debugging programs in the older days. It is also used by IBM RS/6000 systems, Mac OS on 32-bit PowerPC processors and the Commodore Amiga as a magic debug value. On Sun Microsystems' Solaris, it marks freed kernel memory. On OpenVMS running on Alpha processors, DEAD_BEEF can be seen by pressing CTRL-T.[3]"
