All right, learning a little bit more about computer science, kind of one step at a time here talking about interrupts and interrupt handling and understanding that there's different kinds of interrupts that are going to happen.
00:14
You know, you can think about your standard cpu interrupts that trigger at the end of a time slice so that it can be sent off for the next process.
00:26
But there's also interrupts, for example, in the case of real -time computing, you know, the fact that a user is, you know, clicking and dragging on the screen might have to interrupt the process that's currently happening in the background so that the user gets that real -time experience.
00:41
One of the examples that we think about for interrupt handling would be an example of if there's a power failure.
00:48
We like to think, we forget, you know, as humans, we live in a world of seconds and minutes, and we forget just how many instructions can be executed in the length of time from when the computer loses power to when it actually loses all of its voltage.
01:06
And so in that time, an interrupt, a high priority interrupt, will take over the cpu and allow last minute, like essentially data storing to take place before all voltage is gone from the machine...
