Properties of different architectures

Software architectures are the blueprint of a software system. They consist of all components involved in a system, relations between various components, the environment of operation, and the principle used in designing the software. In other words, software architecture shows the organization of different software structures and helps understand their behavior.

Assume a fully associative cache with 4 lines. Assume that the initial state of the tags are Joe,
Kim, Sue, and Meg respectively as shown below. Applying the LRU policy, complete the table
below for the following tag address sequence: Joe -> Dan -> Sue
You can complete the table by replacing labels noted from A through P. Note
that the TAG will be the names and COUNT will be numbers. The first column

Python help Choose the right data structure (Stack, Queue, Deque) and create a function that takes two file (first_file, updated_file) where first_file has alot of duplicated strings, and updated_files is file that takes out any duplicated string from first_file and write it to update_files
Question 15 Consider the following linked list: 2800 92 1500- info link 2000 1500 3600 head 2000- 2000- info link 17 63 3600- 45 info link info link Mark the correct choices (there can be more than one correct choice). Your answer: The value of head = head->link is a valid statement The value of head->link is 92 head->link = 1000 is a valid statement head->link->value = 100 is a valid statement head->link = head->link->info is a valid statement Submit
2. Each student at Middlesex County College takes a different number of courses, so the registrar has decided to use linear linked lists to store each student's class schedule and an array to represent the entire student body. A portion of this data structure is shown below: link Sec cr CSC16213 →HISHO 24 $||1|| 1/1234 2/2 357 CSC236/4 37 These data show that the first student (ID: 1111) is taking section 1 of CSC162 for 3 credits and section 2 of HIS101 for 4 credits; the second student is not enrolled; the third student is enrolled in CSC236 section 4 for 3 credits. s Write a class for this data structure. Provide methods for creating the original array, inserting a student's initial class schedule, adding a course, and dropping a course. Include a menu-driven program that uses the class.

How many fields can the specified log processing function access in a log entry? Calculating average cache miss rates per entry using 64-byte blocks and no prefetching is done using the following code.
cache.xls (or it can be a google sheet that you share with me in a cache.txt with the url in it )= a spreadsheet showing the cycle counts of a cached and non-cached machine. Also, you need to show the cache as the memory accesses progress in your program marking the hits and misses (misses in RED). You should have cells to show how many hits and how many misses your program has, and details on what is the cache replacement policy you implemented. Here is code: void c_cache_for_badge() { int na = 8, nb = -3, nc = 10; // pointers int *npa; npa = (int*)malloc(sizeof(int)*84); // init integer pointers for(int i = 0; i < 84; i++) { npa[i] = i; } // integer pointers for(int i = 9; i < 70; i= i + 3) { nb += npa[i % 5] + npa[i % 3] + npa[i % 6]; } } void main() { c_cache_for_badge(); }
Caching data may improve performance by taking use of "spatial locality" and "temporal locality." Caches employ these two occurrences in many ways.
