The term "collection" contains the word "collect." If you enjoy collecting things, there's a good chance you already have a collection of some kind.
4 The Concept of "Collection" A collection is a gathering of things that have been picked out with a specific goal in mind. Similar ideas include Set, Aggregation (data modeling), Dataset (science and business), and Corpus (linguistics and literary analysis). We favor collecting since it is less defined and has fewer connotations.
Old French collection, a noun of action from the past-participle stem of colligere ('gather together'), is derived from Latin collectionem (nominative collectio), which means 'a gathering together'.

Given the following word addresses: 3, 180, 43, 2,191, 88, 190, 14, 181, 44, 186, 253
a. Show the final cache contents for a three-way set associative cache with two-word blocks and a total size of 24 words. Use LRU replacement. For each reference identify the index bits, the tag bits, the block offset bits, and if it is a hit or a miss.
b. Show the final cache contents for a fully associative cache with one-word blocks and a total size of 8 words. Use LRU replacement. For each reference identify the index bits, the tag bits, and if it is a hit or a miss.
c. What is the miss rate for a fully associative cache with two-word blocks and a total size of 8 words, using LRU replacement? What is the miss rate using MRU (most recently used) replacement? Finally what is the best possible miss rate for this cache, given any replacement policy?
Answer:
A. index bits = 2, tag bits = 2, block offset bits = 1, it is a miss.
B. index bits = 2, tag bits = 1, block offset bits = 0, it is a hit
C. the miss rate is 0
Explanation:
a. number of blocks = 12
number of blocks per set = 3
number of set = number of blocks / number of blocks per set = 12/3 = 4
word size = 24
block size = 2
the block offset = [tex]log_{2}[/tex] block size
= [tex]log_{2}[/tex] 2 = 1
the index bits = [tex]log_{2}[/tex] number of set = [tex]log_{2}[/tex] 4 = 2
the tag bits = ([tex]log_{2}[/tex] word size) - offset - index = ([tex]log_{2}[/tex] 24) -2 - 1 = 5 -2 - 1 = 2
b. word size = 8
block size = 1
the block offset = [tex]log_{2}[/tex] block size
= [tex]log_{2}[/tex] 1 = 0
the index bits = [tex]log_{2}[/tex] number of set = [tex]log_{2}[/tex] 4 = 2
the tag bits = ([tex]log_{2}[/tex] word size) - offset - index = ([tex]log_{2}[/tex] 8) -2 - 1 = 3 - 0- 2= 1
Which statement will read an entire line of input into the following string object?
Select one:
a. cin << address;
b. cin address;
c. getline(cin, address);
d. cin.get(address);
e. None of these
Answer:
getline(cin, address);
Explanation:
Given
String object: address
Required
Statement that reads the entire line
The list of given options shows that the programming language is c++.
Analysing each option (a) to (e):
a. cin<<address;
The above instruction will read the string object until the first blank space.
Take for instance:
The user supplied "Lagos state" as input, only "Lagos" will be saved in address using this option.
b. cin address:
This is an incorrect syntax
c. getline(cin,address);
Using the same instance as (a) above, this reads the complete line and "Lagos state" will be saved in variable address
d. cin.get(address);
address is created as a string object and the above instruction will only work for character pointers (i.e. char*)
From the above analysis, option (c) is correct.

Ben wants to create a Book class that has an instance variable serialNumber. Where should he declare the instance variable
Answer:
within the Book class but needs to also be outside of any methods.
Explanation:
If Ben is creating an entire Book class then the instance variable needs to be within the Book class but needs to also be outside of any methods. If Ben places the variable inside a method it can only be used by that method and therefore becomes an instance variable of that method and not the class. By creating it inside the class and outside the methods it can be used every single time a Book object is created. Therefore, creating an instance variable of serialNumber every time.

Assume you are given a boolean variable named isNegative and a 2-dimensional array of ints that has been created and assigned to a2d. Write some statements that assign true to isNegative if more integer elements in entire 2-dimensional array are negative than not.
Answer:
#include <iostream>
using namespace std;
int main(){
int rows, cols;
bool isNegatives;
cout<<"Rows: ";
cin>>rows;
cout<<"Columns: ";
cin>>cols;
int a2d[rows][cols];
for(int i =0;i<rows;i++){
for(int j =0;j<cols;j++){
cin>>a2d[i][j];} }
int negatives, others = 0;
for(int i =0;i<rows;i++){
for(int j =0;j<cols;j++){
if(a2d[i][j]<0){
negatives++;}
else{
others++;}} }
if(negatives>others){
isNegatives = true;}
else{
isNegatives = false;}
cout<<isNegatives;
return 0;
}
Explanation:
For clarity and better understanding of the question, I answered the question from the scratch.
This line declares number of rows and columns
int rows, cols;
This line declares the Boolean variable
bool isNegatives;
This line prompts user for rows
cout<<"Rows: ";
This line gets the number of rows
cin>>rows;
This line prompts user for columns
cout<<"Columns: ";
This line gets the number of columns
cin>>cols;
This line declares the array
int a2d[rows][cols];
This line gets user input for the array
for(int i =0;i<rows;i++){
for(int j =0;j<cols;j++){
cin>>a2d[i][j];} }
This line declares and initializes number of negative and others to 0
int negatives, others = 0;
The following iteration counts the number of negatives and also count the number of non negative (i.e. others)
for(int i =0;i<rows;i++){
for(int j =0;j<cols;j++){
if(a2d[i][j]<0){
negatives++;}
else{
others++;}} }
This checks of number of negatives is greater than others
if(negatives>others){
If yes, it assigns true to isNegatives
isNegatives = true;}
else{
If otherwise, it assigns false to isNegatives
isNegatives = false;}
This prints the value of isNegatives
cout<<isNegatives;

c
icons
d
USB cord
Answer:
The answer to this question is given below in the explanation section.
Explanation:
First, we need to know what is the graphic user interface (GUI)?
A GUI is a form of user interface that allows the users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of a text-based user interface as in MS-DOS. Users interact through such devices using their icon, navigation using the mouse cursor, etc , and touching. In short, an interface that has graphical options.
so, in the context of the question, the following are examples of GUI.
Virus protection software: Because virus protection software has a graphical interface and user can use it easily by using its graphics and exploration functionality.
Icon: icon is an example of GUI because ICON built on other many graphics parts. In short, the icon is part of the GUI.
The followings are not the example of GUI:
Microphone and USB cord because these are the electronic parts and they don't possess the GUI.
