To keep a watchdog timer from resetting your system, you've got to kick it regularly. But that's not all there is to watchdog science. We will examine the use and testing of a watchdog, as well as the integration of a watchdog into a multitasking environment.

Which is the most convenient end on your system? The choices are big endian and little endian.

Some human languages are read and written from left to right; others from right to left. A similar issue arises in the field of computers, involving the representation of numbers.
