Question

question 9 (mandatory) (1 point) what is an interrupt in the context of operating systems? a method for allocating resources a signal that temporarily halts the cpu to address a higher - priority task a type of data transfer protocol a delay in processing tasks question 10 (mandatory) (1 point) which of the following types of devices commonly uses dma for efficient data transfer? hard drives keyboards mice monitors

Explanation:

• For Question 9: An interrupt in operating - systems is a signal that causes the CPU to temporarily stop its current task to handle a higher - priority task. This is different from resource allocation, data transfer protocols, or processing delays.
• For Question 10: Direct Memory Access (DMA) is commonly used by hard drives for efficient data transfer as they need to move large amounts of data without excessive CPU intervention. Keyboards, mice, and monitors do not typically use DMA for their data transfer operations.

Answer:

Question 9: B. A signal that temporarily halts the CPU to address a higher - priority task
Question 10: A. Hard drives
