The heart of the recent hit game simaquarium is a tight loop that calculates the average position of 256 algae. you are evaluating its cache performance on a machine with a 1024-byte direct-mapped data cache with 16-byte blocks (b = 16). you are given the following definitions:struct algae_position {int x; int y;};struct algae_position grid[16][16];int total_x = 0, total_y = 0;int i, j;//grid begins at memory address 0//the only memory accesses are to the entries of the array grid. i,j,total_x,total_y are stored in registers//assuming the cache starts empty, when the following code is executed:for (i = 0; i < 16; i++) {for (j = 0; j < 16; j++) {total_x += grid[i][j].x;]}for (i = 0; i < 16; i++) {for (j = 0; j < 16; j++) {total_y += grid[i][j].y;}}required:a. what is the total number of reads?b. what is the total number of reads that miss in the cache?c. what is the miss rate?

Create an array of MY_STRING handles with 100 elements. Initialize each element of the array to NULL. Use your init_c_string function to initialize the first element of the array to the string "COPY ME!". Write a for loop that uses your assignment function to copy the first string into every other element of the array. Destroy every element of the array with a for loop calling destroy on each element but use string_insertion to print each element to the screen just before deleting it. TA CHECKPOINT 2: Demonstrate to your TA that your program has no memory leaks using valgrind. Demonstrate that by commenting out the for loop that destroys your strings you can create a memory leak big enough to hold 100 copies of the "COPY ME!" string

1. Suppose your ISP gives you the address space 18. 28. 32. 0/25. There is a core router and three subnets under the core router. Each of the three subnets have two hosts each. Each subnet will also need to assign an address to its corresponding router and the hosts. Write down the addresses you will assign to the 6 hosts, to the three subnet routers, and to the core router responsible for the address 18. 28. 32. 0/25. Also specify the address range of each router (10 points)

You are working for a company that wants to separate its network of 100 workstations into two separate subnets. Right now, they have a single router (A) that connects their internal network to the Internet. They have purchased a second router (B), which will serve as an internal router. Approximately half of their workstations will connect to the internal (LAN) port on Router A, and the other half will connect to the internal (LAN) port on Router B. Required:Configure Router A so that a machine attached to an internal (LAN) port on Router A can connect to another machine connected to the internal (LAN) port on Router B
