Answer 1

There can be several interrupts with different priorities.
The normal execution of the code is interrupted and instead the code is executed by certain interrupt. Afterwards the standard code can be continued (but does not have to).

Answer 2

An interrupt is like a signal that must be handled in the code. A bit like an event.
