Match the items in $\textbf{List-I}$ and $\textbf{List-II}$ :

$\begin{array}{clcl} {} & {\textbf{List-I}}  & {} & {\textbf{List-II}} \\  \text{(a)} &  \text{interrupts which can be delayed when a much} & \text{(i)} &  \text{Normal}\\ & \text{highest priority interrupt has occurred} \\ \text{(b)} & \text{Unplanned interrupts which occur while executing} & \text{(ii)} & \text{Synchronous}\\&\text{a program } \\  \text{(c)} & \text{Source of interrupt is in phase with the system} & \text{(iii)} & \text{Maskable} \\ & \text{clock}\\   & \text{ } & \text{(iv)} & \text{Exception}\\  \end{array}$

$\textbf{Code :}$

  1. $\text{(a)-(ii), (b)-(i), (c)-(iv)}$
  2. $\text{(a)-(ii), (b)-(iv), (c)-(iii)}$
  3. $\text{(a)-(iii), (b)-(i), (c)-(ii)}$
  4. $\text{(a)-(iii), (b)-(iv), (c)-(ii)}$

The hardware interrupts which can be delayed when a much high priority interrupt has occurred at the same time- Maskable interrupt.

Unplanned interrupts while executing a program is called Exception.

Source of interrupt is in phase with the clock : Synchronous .

For theoretical understanding refer to Mano book Chapter 11

Exception: unplanned interrupts while executing a program is called Exception. For example: while executing a program if we got a value which should be divided by zero is called a exception

Maskable Interrupt: The hardware interrupts which can be delayed when a much highest priority interrupt has occurred to the processor.

Synchronous Interrupt: The source of interrupt is in phase to the system clock is called synchronous interrupt. In other words interrupts which are dependent on the system clock. Example: timer service that uses the system clock.

so D answer

 

more information 

Internal interrupt Interrupt which arises from illegal or erroneous use of an instruction or data

ex Register overflow, stack overflow, Protection violation

Software interrupt: System calls intentionally written by programmer

External interrupt : hardware error like power failure, memory parity error,I/O controller,Timer( internal processor timer is used in pre-emptive multi-tasking)

Asynchronous Interrupt: If the interrupts are independent or not in phase to the system clock is called synchronous interrupt.

Periodic Interrupt: If the interrupts occurred at fixed interval in timeline then that interrupts are called periodic interrupts

Hardware interrupt : temperature sensor etc

Maskable Interrupt :
Maskable Interrupts are those which can be masked/delayed when a higher priority interrupt occurs.
Exception :
Exception are the unplanned interrupts that occur while executing a program. Divide by zero is an example of Exception.
Synchronous:
Synchronous clocks will regularly synchronize their time with a master clock. The connection can be direct (wired), or over the air (radio, wifi or similar). The connections can be at a regular intervals, on demand or a mix.
