Q.1. (9 points) True or False: 1. T/F The memory devices used in a computer form a hierarchy based on a set of characteristics. ANS: 2. T/F The lowest level of memory in the hierarchy is the closest to the processor. ANS: 3. T/F External memory capacity is represented in bytes. ANS: 4. T/F The size of a word is typically equal to the number of bits required to represent an integer ANS: 5. T/F - Semiconductor ROM memory is a nonerasable but volatile type of memory ANS: 6. T/F - If the memory has faster access time, then the cost per bit is less. ANS: 7. T/F A hit occurs when the word requested can be accessed from the lowest memory in the hierarchy. ANS: 8. T/F Data stored in secondary or auxiliary memory is represented in terms of files or records. ANS: 9. T/F - Direct mapping implies that the number of lines in the cache must be equal to the main memory. ANS
