Task 1 Suppose we are processing 100 data records on a CPU cache. Each data record is 32 bytes in size. And each 10 operation will fetch a 64 byte cache line. Suppose the 100 data records on the cache are contiguously stored. In this case, is sequential reading faster than random reading? How much faster? What if each data record is 64 bytes in size instead of 32 bytes? ANSWER: 1. Sequential reading is faster than random reading. Suppose reading one block from the disk to the memory takes 1ms, and writing one block from memory to disk takes 1ms as well. What is the time needed to read/write A1,A2,A3, and A4 under each of the three storage architecture
