Answer:
Tag = 1
Index = 5
Block offset = 2
Explanation:
From the given information:
The main memory bits(MM) = 221
number of block in the cache = 64 blocks
Block size = 4B
Recall that;
MM = log (memory size)
Thus;
main memory bits = log (221)
= 8 bits
Since this is a 2-way assoicative set;
the number of set in each cache = block size/2
64/2 = 32
Now, the index bit = log( no of set in each cache)
= log(32)
= 5 bits
Also since block size = 4B;
the block offset = log(4) = 2 bits
As such, tag = main memory bits - (index bit + block offset)
tag = 8 -(5 + 2)
tag = 8 -7
tag = 1

I need solutions to below questions with python code:
Write a program, my_family.py For Loop A program, work-list.pyList
1. that contains a Tuple holding the names of friends or family members. Then use a For Loop to read and print the names.
2. that contains a of six integers. Use a list method to add one more integer. Use a list method to sort the list. Use a While Loop to print the entries.
Answer:
1) my_family.py
family = ('Dad', 'Mom', 'Agnes', 'David', 'Chris', 'Millie')
for name in range(len(family)):
print(family[name])
2) work_list.py
my_number = [2, 6, 3, 1, 8, 4]
# add items at the end of the list.
my_number.append(0)
my_number.append(5)
# sorts the list, default - ascending.
my_number.sort()
size = 0
while size < len(my_number):
print(my_number[size])
size += 1
Explanation:
The tuple and list data structures are ordered, using indexes to locate items in its container.
The family.py file uses the for-loop to iterate and print the family names in the tuple.
The work-list.py file contains a list of integers which is modified by adding items at the end of the list with the append method and a prints all the items using a while-loop.
Static methods can be called directly from the name of the class that contains the method.
a. True
b. False

At times, what seems to be an effective value network can also be vulnerable to quickly losing effectiveness. At one time, Sony Corporation set up a value network designed to have a "one-stop" gaming experience for its customers. From 2003 to 2008, Sony designed an all-encompassing gaming portal. However, the network was disrupted when computer hackers began breaking into the system and retrieving sensitive banking data from the network users. As a result, the effectiveness of the network was severely compromised.

Answer:
Cognitive loadLanguageWatchEditIn cognitive psychology, cognitive load refers to the used amount of working memory resources. There are three types of cognitive load: intrinsic cognitive load is the effort associated with a specific topic; extraneous cognitive load refers to the way information or tasks are presented to a learner; and germane cognitive load refers to the work put into creating a permanent store of knowledge (a schema).Cognitive load theory was developed in the late 1980s out of a study of problem solving by John Sweller.[1] Sweller argued that instructional design can be used to reduce cognitive load in learners. Much later, other researchers developed a way to measure perceived mental effort which is indicative of cognitive load.[2][3] Task-invoked pupillary response is a reliable and sensitive measurement of cognitive load that is directly related to working memory.[4] Information may only be stored in long term memory after first being attended to, and processed by, working memory. Working memory, however, is extremely limited in both capacity and duration. These limitations will, under some conditions, impede learning. Heavy cognitive load can have negative effects on task completion, and it is important to note that the experience of cognitive load is not the same in everyone. The elderly, students, and children experience different, and more often higher, amounts of cognitive load.The fundamental tenet of cognitive load theory is that the quality of instructional design will be raised if greater consideration is given to the role and limitations of working memory. With increased distractions, particularly from cell phone use, students are more prone to experiencing high cognitive load which can reduce academic success.[5]Explanation:

An analyst suggests that the lower the number of clusters, would give us the strongest and most meaningful result, as opposed to a large number of clusters.
a. True
b. False
Answer:
a. True
Explanation:
Various studies have shown that this is true. Clusters allow you to group together large sets of data into smaller groups in order to find similarities between all the data. Having a smaller number of clusters has been proven to allow you to discover much simpler similarities which can have a much greater impact. Larger sets can help in discovering more unique similarities but they do not have as large of an impact and are less meaningful. This is also why it is recommended to have a lower number of clusters when analyzing data sets.

Implement a class named MyArrayList that extends class the java.util. ArrayList. The class MyArrayList overrides the add(obj) method in the following way: it adds obj into the list if the object does not occur in the list or it occurs in the list only once; otherwise, if the object occurs in the list more than once, then the method does nothing.
Answer:
import java.util.ArrayList;
import java.util.Collections;
public class MyArrayList<T> extends ArrayList<T> {
public boolean add(T obj) {
if (Collections.frequency(this, obj) < 2) {
return super.add(obj);
}
return false;
}
}
Explanation:
According to the requirement, an element with the same value can occur at most twice in the list.
The Collections.frequency utility is useful to count the occurrances.
Sure, here's an implementation of the `MyArrayList` class that extends `java.util.ArrayList` and overrides the `add` method as described:
```java
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;
public class MyArrayList<E> extends ArrayList<E> {
"ATTHERATE"Override
public boolean add(E obj) {
// Count occurrences of each element in the list
Map<E, Integer> countMap = new HashMap<>();
for (E element : this) {
countMap.put(element, countMap.getOrDefault(element, 0) + 1);
}
// Check if obj occurs in the list only once or not at all
if (!countMap.containsKey(obj) || countMap.get(obj) == 1) {
return super.add(obj);
}
// If obj occurs more than once, do nothing
return false;
}
}
```
In this implementation, the `add` method first counts the occurrences of each element in the list using a `HashMap`.
Then, it checks whether the given object `obj` occurs only once or not at all in the list. If so, it adds the object to the list using the `super.add(obj)` call.
If `obj` occurs more than once, the method does nothing by returning `false`. This way, the `MyArrayList` class ensures that duplicates are added only once, or not at all, as required.

UNIX inodes are an example of an indexed file allocation scheme. What levels of indexing were they designed to support. A. Direct B. Single indirect C. Double indirect D. Triple indirect E. All of the above are supported by UNIX inodes.
Answer: E. All of the above are supported by UNIX inodes
Explanation:
An inode refers to the data structure that's in the UNIX operating systems which consists of vital information that has to do with the files that's within a file system.
It should be niteec that when there's creation of a file system in UNIX, then a set amount of inodes will be created too.
The levels of indexing that the UNIX inodes were designed to support include the direct, single indirect, double indirect and the triple indirect. Therefore, the correct option is E.
Write a program that receives a filename as user input. The file is structured as multiple lines containing numbers separated by a single space. For example, this would be an acceptable file:
Answer:
The solution in Python is as follows:
filename = input("File: ")
fll = open(filename, "r")
for line in fll:
for i in line.split():
print(i,end='\t')
print()
Explanation:
The complete question implies that the program reads a file and displays the file content in a structured way (tabs or spaces)
The explanation is as follows:
This gets input for the file name
filename = input("File: ")
This opens the file for read operation
fll = open(filename, "r")
This iterates through the lines of the file
for line in fll:
This iterates through each line (splitted by space)
for i in line.split():
This prints the current element followed by a tab
print(i,end='\t')
This starts printing on another line

iii. True
Explanation:
Machine and assembly are referred to as a low level programming language used in writing software programs or applications with respect to computer hardware and architecture. Machine language is generally written in 0s and 1s, and as such are cryptic in nature, making them unreadable by humans but easily understandable to computers.
In view of the above, we can deduce that programming in machine level language is very difficult for humans.

y=ax²+bx+c
Answer:
The program in Java is as follows:
import java.util.Scanner;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
float a, b, c, x, y;
a = input.nextFloat();
b = input.nextFloat();
c = input.nextFloat();
x = input.nextFloat();
y = a * x * x + b * x + c;
System.out.print(y); }}
Explanation:
This declares all variables
float a, b, c, x, y;
The next 4 lines get input for a, b, c and x
a = input.nextFloat();
b = input.nextFloat();
c = input.nextFloat();
x = input.nextFloat();
This calculates the value of y using [tex]y = ax^2 + bx + c[/tex]
[tex]y = a * x * x + b * x + c;[/tex]
This prints the calculated value of y
System.out.print(y);

Select one:
A.Remote Information Access
B.Interaction among cooperative application programs
C.Social Engineering
D.User Communication
E.Resource Sharing
Answer:
C. Social Engineering
Explanation:
Social engineering can be defined as an art of manipulating people, especially the vulnerable to divulge confidential information or performing actions that compromises their security.
Basically, it is a manipulative strategy or technique that involves the use of deceptive and malicious activities on unsuspecting victims in order to gain unauthorized access to their confidential or private information for fraud-related purposes. Some examples of social engineering attacks include quid pro quo, spear phishing, baiting, tailgating, water-holing, vishing, pretexting, phishing, etc.
Phishing is an attempt to obtain sensitive information such as usernames, passwords and credit card details or bank account details by disguising oneself as a trustworthy entity in an electronic communication usually over the internet.
Furthermore, phishing is a type of fraudulent or social engineering attack used to lure unsuspecting individuals to click on a link that looks like that of a genuine website and then taken to a fraudulent web site which asks for personal information.
In conclusion, social engineering being a form of cyber attack is not an advantage of a computer network.
