5-32. What cache process is performed by a requestor other than the CPU within? 1.  Main 2.  Mapping 3.  Eavesdrop 4.  Searching IN ANSWERING QUESTIONS 5-33 THROUGH 5-36, SELECT FROM THE FOLLOWING LIST THE CACHE MAPPING TECHNIQUE DESCRIBED IN EACH  QUESTION. 5-33. 5-34. 5-35. 5-36. 5-37. 5-38. 5-39. 1.  Direct  mapping 2. Fully associative mapping 3. Set associative mapping Is the most flexible cache mapping technique with regards to where data can reside. Combines the best cache mapping techniques. Main memory locations can only be copied into one location in cache. If cache is full, a replacement algorithm is used to decide which block gets replaced by new data. What cache read method can be used to present the cache and main memory with the reference simultaneously? 1. Look-aside, serial read 2. Look-aside, parallel read 3. Look-through, serial read 4.  Look-through,  parallel  read In a look-through read, the cache is checked last. 1.   True 2.   False Optimum cache replacement would be psychic and have perfect knowledge of the future. What cache replacement policy, if any, comes closest to the optimum cache replacement? 1.   LRU 2.   FIFO 3.  Random 4. None, all are very different 5-40. Instruction routines in a ROM are considered to have which of the following characteristics? 1.  Permanent  and  volatile 2.  Permanent  and  nonvolatile 3.  Temporary  and  volatile 4.  Temporary  and  nonvolatile 5-41. Permanent software loaded as firmware is the process known by which of the following terms? 1.  Boot 2.  Bootstrap 3. Boot up 4. Each of the above 5-42. An NDRO in a militarized mainframe or minicomputer is usually located in which of the following   places? 1. In the CPU module 2. In the chassis that contains CPU’s pcbs 3. Either 1 or 2 above, depending on whether it is a mini or mainframe computer 4. On one or more IC chips of a CPU/memory p c b 5-43. Diagnostics programs on an NDRO include all of the following items except which one? 1. Test the timer 2.  Load  failure  analysis 3. Memory and interface tests 4.  Computer  interconnection  system IN ANSWERING QUESTIONS 5-44 THROUGH 5-47, SELECT FROM THE FOLLOWING LIST THE AREA OF A BIOS DESCRIBED IN EACH QUESTION 5-44. 5-45. 5-46. 1. Diagnostic testing 2.  Environmental  inventory 3. Boot procedure Testing the video, interrupt controller, CPU register and flags, or the keyboard. A prompt is displayed to let you know the microcomputer is ready to use. The ROM chip program searches for the operating system files. 31
