In this post, we start exploring CPU exceptions. Exceptions occur in various erroneous situations, for example when accessing an invalid memory address or when dividing by zero. To catch them, we have to set up an _interrupt descriptor table_ that provides handler functions. At the end of this post, our kernel will be able to catch [breakpoint exceptions] and to resume normal execution afterwards.

To react to them we have to set up an _interrupt descriptor table_ that provides handler functions.
