Question

Assume a computer system has a main memory of 256 Bytes. The following is a memory byte-access trace history of  a program run on this system. For example, as it is shown, the program first accesses memory address 0000 0000, and  then it accesses memory address 0000 0001 and so on. Note the memory addresses are represented in binary: 00000000, 00000001, 00000010, 00000011, 00001000, 00010000, 00010001, 00000100, 00000101, 00000110, 00000111, 00001001, 00001010, 00001011, 00001100, 00001000, 00001001, 00001010, 00011100, 00011101.
