The memory hierarchy of a computer system organizes storage by using small, fast, expensive memories at the top of the hierarchy and supplementing them with larger, slower, cheaper memories at each successive level. Explain how the principle of memory locality makes such a system capable of providing efficient access to the data and instructions needed for executing programs.

Answer:

Following are the responses to this question:

Explanation:

The computer system's memory hierarchy arranges space through tiny, fast, costly stocks only at top of the pyramid and complements them through big, lighter, cheap storage facilities at every representation made. It is needed to limit the time for data access for application executes. A very design of the main memory allows a system to have easy access to the information and instructions necessary to execution time. A traditional technique of system memory works like:

[tex]Level\ 0 (Top Level) \to CPU \ Registers\\\\Level \ 1 \to Cache\ Memory \ (SRAMs)\\\\Level\ 2 \to Main \ Memory \ (DRAMs)\\\\Level \ 3 \to Magnetic \ Disk\ (Disk \ Storage)\\\\Level \ 4 \to Optical \ Disk\\\\Level \ 5 \to Magnetic\ Tape\\\\[/tex]

Because as memory cost rises below level 5 to level 0. CPU registers become costly as the cache memory, which then, in turn, is much more costly than for the memory.

Whenever the access time of CPU registries becomes reduced from level 5 to level 0, its time complexity between reading/write transactions is much more swift than Cache Memory Access period which in turn is quicker than that of the main memory Communication cost and so forth.

So, we need a memory hierarchy to analyze the information (read/write requests) efficiently, in turn for all the top-level to read the information more quickly and thoroughly. Therefore, the architecture of the computer program's Main memory enables a system to provide secure access to information and guidance for running programs.

Remember partially filled arrays where the number of elements stored in the array can be less than its capacity (the maximum number of elements allowed). We studied two different ways to represent partially filled arrays: 1) using an int variable for the numElems and 2) using a terminating value to indicate the end of elements called the sentinel value. In the code below, please fill in the details for reading values into the latter type of array that uses a sentilnel value. Don't forget to complete the printArray function.
#include
using namespace std;
void printArray(int array[]);
// Implement printArray as defined with one array parameter
int main()
{
const int CAPACITY=21;
int array[CAPACITY]; // store positive/negative int values, using 0 to indicate the end of partially filled array
cout <<"Enter up to " << CAPACITY-1 << " non-zero integers, enter 0 to end when you are done\n";
//To do: Write a loop to read up the int values and store them into array a.
// Stop reading if the user enters 0 or the array a is full.
//To do: store 0 to indicate the end of values in the array
//Display array function
printArray(array);
return 0;
}
// To do: implement display for the given array
void printArray(int array[])
{
}

The function below takes one parameter: an integer (begin). Complete the function so that it prints the numbers starting at begin down to 1, each on a separate line. There are two recommended approaches for this: (1) use a for loop over a range statement with a negative step value, or (2) use a while loop, printing and decrementing the value each time. student.py 1 - def countdown_trigger(begin): 2 - for begin in range(begin, 0, -1): 3 print(begin)The function below takes one parameter: a list (argument_list). Complete the function to create a new list containing the first three elements of the given list and return it. You can assume that the provided list always has at least three elements. This can be implemented simply by creating (and returning) a list whose elements are the values at the zero'th, first and second indices of the given list. Alternatively, you can use the list slicing notation. student.py 1 - def make_list_of_first_three(argument_list): 2 WN Ist = argument_list[: 3 ] return IstIn the function below, return the (single) element from the input list input_list which is in the second to last position in the list. Assume that the list is large enough. student.py 1 - def return_second_to_last_element(input_list) :

If we need to manage a contiguous range of memory, handling requests to allocate various sized chunks, and later make those chunks free for reuse (as the malloc() and free() routines do in a C program), we have a number of linked list allocation algorithms that we could choose from. If our primary objective in allocating a chunk was to leave the smallest fragment possible after the allocation, which algorithm would we implement?a. slab allocator.b. worst-fit allocator.c. first-fit allocator.d. best-fit allocator.e. bit-map allocator.

Define a single function named displayResults that returns nothing and takes two input parameters, an array of counters and the singular counter for the number of doubles rolled. The function displays the estimated probability of rolling doubles as well as the estimated probability of rolling each of the potential values from 1 to the maximum number that can be rolled (which can be calculated from the aforementioned input parameters). Recall, estimated probability is the calculated estimate of the theoretical probability of a scenario. To calculate an estimated probability we take the number of occurrences for a scenario and divide by the number of possible occurrences (the number of simulations).

This program reads a file called 'test.txt'. You are required to write two functions that build a wordlist out of all of the words found in the file and print all of the unique words found in the file. Remove punctuations using 'string.punctuation' and 'strip()' before adding words to the wordlist.
Write a function build_wordlist() that takes a 'file pointer' as an argument and reads the contents, builds the wordlist after removing punctuations, and then returns the wordlist. Another function find_unique() will take this wordlist as a parameter and return another wordlist comprising of all unique words found in the wordlist.
Example:
Contents of 'test.txt':
test file
another line in the test file
Output:
['another', 'file', 'in', 'line', 'test', 'the']
This the skeleton for 1:
#build_wordlist() function goes here
#find_unique() function goes here
def main():
infile = open("test.txt", 'r')
word_list = build_wordlist(infile)
new_wordlist = find_unique(word_list)
new_wordlist.sort()
print(new_wordlist)
