Question 1.
What is the purpose of a data buffer?
Show hintHide hint
Think of it like a waiting area for data.
Question 2.
Define a device driver.
Show hintHide hint
It's like a translator for your devices!
3Question 3.
What is the primary function of a device driver?
- To manage data buffers
- To control hardware devices
- To read and write data
Show hintHide hint
Focus on what roles a driver plays in computing.
4Question 4.
True or False: Data buffers reduce the speed of data transfer.
- True
- False
Show hintHide hint
Consider the concept of buffering in communications.
Question 5.
Consider a system using DMA versus programmed I/O for a large file transfer. Evaluate the time taken for both methods given a specific data size and type of operation. Which method is more efficient and why?
Show hintHide hint
Reflect on the operational differences between maintaining CPU involvement and allowing DMA to function independently.
Question 6.
A hard disk has a high seek time but low rotational delay. Discuss the impact this has on overall performance and data retrieval times.
Show hintHide hint
Think about how each component's timing contributes to total access time.
