often triggered by external devices. When an interrupt occurs, the program counter is temporarily saved, and the central processing unit (CPU) jumps to an interrupt handler routine. After handling the interrupt, the program counter is restored to its original value, allowing the interrupted program...
when an irq is triggered, the central processing unit (cpu) halts its current operation, saves the current context, and jumps to the corresponding irq handler routine. the handler processes the interrupt, saves necessary data, performs actions as required, and then restores the cpu context to ...
What is a side effect? Here's a good definition from Wikipedia): In computer science, an operation, function or expression is said to have a side effect if it modifies some state variable value(s) outside its local environment, that is to say has an observable effect besides returning a...
Task EventHandlers break down where the exception is thrown in an earlier executed handler, and we have a handler that follows. If we reverse the order and the Task EventHandler that throws the exception at the end of the invocation, we will get the behavior that we demonstrated in the pre...
