Is there any major difference between the two? Is there anything that can be done in one and not the other? Do I need to take more care when modifying, for example, the page fault handler than a timer handler?

Interrupt is one of the classes of exception. There are four classes of exception: interrupt, trap, fault and abort. Interrupt occurs asynchronously and it is triggered by signal which is from I/O device that are external by processor. After exception handler finish handling this interrupt(exception processing), handler will always return to next instruction.
