1. Explain the relationship and/or differences between the following concept pairs: A. Synchronous vs. asynchronous.
B. Interrupts vs. polling.
C. Traps vs. interrupts.
2A. Explain which of the following I/O methods is most likely interrupt driven. Why?
A. DMA
B. Polling.
2B. A fast laser printer produces up to 20 pages per minute, where a page consists of 4000 characters. The system uses interrupt-driven I/O, where processing each interrupt takes 50 microseconds. How much overhead will the CPU experience if the output is sent to the printer one character at a time? Would it make sense to use polling instead of interrupts?
3. Assume a mouse generates an interrupt whenever its position changes by 0.1 mm. It reports each such change by placing 2 bytes of data into a buffer accessible by the CPU. At what rate (in kb/s) must the CPU retrieve the data if the mouse moves at a speed of 30 cm/second in order to read all the data?
