Quick computer science questions. Answer ALL 41-50 for positive rate.

41. T or F? A "memory stick" is made from nonvolatile flash memory 42. Fact Our text book states, "When you realize that the seek time [for CD-ROMs] is usually several hundred milliseconds, it should be clear that CD-ROM drives are not in the same performance category as magnetic disk drives, despite their large capacity." What one word explains why CD-ROMs are so slow? A: laser B: pits/lands C: spiral D: ECC E: frame 43. T or F? A Blu-ray recorded DVD has a higher fidelity because the blue laser used to read the data stored on the DVD allows for a higher recording density 44. T or F? Analogy. device driver: hardware:: device controller : software 45. Which one of the following directly accesses memory when an I/O device interface uses DMA to accomplish input and/or output. A: the device itself B: the device's interrupt handler C: the device's controller D: the device's driver E: none of these 46. T or F? An interrupt is a hardware event that causes software to execute. 47. Cycle stealing steals CPU clock cycles from A: computer memory_B: bus C: CPU D: I/O devices E: none of these 48. T or F? Buses only purpose is to connect device controllers to main memory to provide direct memory access. 49. T or F? The PCI bus with 32 wire pair lanes "looks" very much like a 32-bit wide parallel interface. 50. Our text book states, "When the transfer is completed, the controller normally causes an interrupt, forcing the CPU to immediately suspend running its current program and start running a special procedure, called an interrupt handler, to check for errors..." T or F? An interrupt is a software action caused by the controller
