A)
Explanation of Solution
Cache entry and cache byte:
The program running on a machine references the 1-byte word at address “Ox0DD5”. Hexadecimal is a number system of base 16As and as hex system has 16 digits, the extra needed 6 digits are represented by the first 6 letters of English alphabet which means “ 0,1,2,3,4,5,6,7,8” represents “9,A,?B,?C,?D,?E,?F” respectively in decimal system.
First, one needs to convert the hexadecimal address into binary form:
One needs to consider the following set associative (S, E, B, m) = (8, 4, 4, 13). The derived value will be as follows:
The Index (CI):
B)
Explanation of Solution
Memory reference:
The address format (1 bit per box) for address “Ox0DD5” is hence represented as:
CT | CT | CT | CT | CT | CT | CT | CT | CI | CI | CI | CO | CO |
0 | 1 | 1 | 0 | 1 | 1 | 1 | 0 | 1 | 0 | 1 | 0 | 1 |

- what is a feature in the Windows Server Security Compliance Toolkit, thank you.arrow_forwardYou will write a program that allows the user to keep track of college locations and details about each location. To begin you will create a College python class that keeps track of the csollege's unique id number, name, address, phone number, maximum students, and average tuition cost. Once you have built the College class, you will write a program that stores College objects in a dictionary while using the College's unique id number as the key. The program should display a menu in this order that lets the user: 1) Add a new College 2) Look up a College 4) Delete an existing College 5) Change an existing College's name, address, phone number, maximum guests, and average tuition cost. 6) Exit the programarrow_forwardShow all the workarrow_forward
