Answer 2

Answer:

Buffer is a temporary memory, where data is stored in the buffer memory only for a while.

Interrupt means a signal, where one component sends a signal to another component, that a particular task is one.

The CPU uses DMA (Direct memory access) to temporarily store some information and when DMA completes the operation, it signals to the CPU that it has done. In this method, CPU time is efficiently used.
