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?

some have built technology like spoofed call blockers into their networks, so there's nothing you would even have to install.

this happens because the number is known for scamming, they don't want it to me known as "scam likely." perhaps it's just a telemarketer. maybe it's an identity thief. it might even be a scam artist.  

either way, "scam likely" is probably not an old friend whose number you forgot that you saved. it's your wireless carrier's way of letting you know: answer at your own risk.

explanation:

to combat the seemingly rising epidemic of spam callers in the u.s., the nation's four major wireless carriers have been trying out new methods to reduce the number of unsolicited calls americans receive each day.

hope this . mark me brainliest.
