If Scheme were a pure functional language, could it include DISPLAY ? Why or why not?
Answer:
When Scheme is a pure functional language, it cannot include the function DISPLAY. Since the pure functional languages will return the same value whenever the same expression is evaluated, and the DISPLAY would be the output and thus it cannot be part of the purely functional language. Thus in the pure functional language we can evaluate the expressions with the same arguments and it returns the same value since there is no state to change.

What is indirect program memory addressing? Explain the working of the following instructions?
a) JMP AX
b) JMP LIST[DX]
c) JMP NEAR PTR[DI+3]
The instructions operate as follows:
a)
JMP AX :
The JMP instruction is being used to execute an unconditional jump.AX is indeed the label's name. JMP AX codes are being used to transfer control of the flow program to the AX label.b)
JMP LIST:
The JMP command can be used to execute an unconditional jump, JMP LIST[DX] is the label's name. The JMP LIST[DX] program is being used to transfer control of its flow programs to the specified section. It is the segment to which the flow control is transmitted.c)
JMP NEAR PTR[DI+3]:
Unconditional jumps could be done with the JMP command as you'll see, the label is JMP NEAR PTR[DI+3]. It's being used to transmit flow control to a particular section, throughout this case [DI+3]. The close keyword indicates that perhaps the code segment would be in the line of code being nearby.Learn more:

As described in class, what does the sender send to the receiver when using hashing for integrity and authentication? (Do not include information previously shared / agreed upon by the sender and receiver.)
Answer:
The answer is "secret key k".
Explanation:
When the sender sends the message, he/she may combine, it with the hidden key, and determines the hashing, when transmitting the information the digest is being sent, and also the message is transmitted through the connection.
when the receiver receives the message, still having the very same secret key, adding the Hidden Key then recalculating the hashing again. In this, two factors if another subsequent digest matches something, this message is sent.
During transit, the message was certainly not changed. Anybody with the private key – preferably even a preferred sender sent out this letter.What are the basic characteristics of object-oriented analysis and design (OOAD)? How does OOAD compare to structured analysis and design (SAD)?
Answer:
Basic characteristics of OOAD and compression with SAD can be defined as follows:
Explanation:
The Object-oriented analysis is described as a design and analysis system like an application, that uses Oops programming. It is the measurement model, that is the presentation, which became a part of the object-based review.
The features of OOAD can be defined as follows.
The complex issues are simply solved. The operation of very fast recovery. The stability in condition changes. Its conceptual method for resolving its extremely complex problems.The difference in OOAD and SAD can be defined as follows:
The OOAD mainly focuses upon the design of objects, it can be used in highly complex logical systems, whereas the SAD focuses on data analysis systems and processes. The OOAD uses the framework to target data, but the SAD is process-oriented. It uses class and UML diagrams, but SSAD uses DFDs to extract the element, it has many limited steps to prepare and execute, but OOAD relies mostly on initial growth. This method is being developed in the course of the process.Add each element in origList with the corresponding value in offsetAmount. Print each sum followed by a space. Ex: If origList = {40, 50, 60, 70} and offsetAmount = {5, 7, 3, 0}, print:45 57 63 70 #include using namespace std;int main() {const int NUM_VALS = 4;int origList[NUM_VALS];int offsetAmount[NUM_VALS];int i = 0;origList[0] = 40;origList[1] = 50;origList[2] = 60;origList[3] = 70;offsetAmount[0] = 5;offsetAmount[1] = 7;offsetAmount[2] = 3;offsetAmount[3] = 0;// your solution goes here
Answer:
Complete the program with the following code segment
for(int i =0;i<=3;i++)
{
cout<<offsetAmount[i]+origList[i]<<" ";
}
return 0;
}
Explanation:
The following line is an iteration of variable i from 1 to 3; It iterates through elements of origList and offsetAmount
for(int i =0;i<=3;i++){
This adds and prints the corresponding elements of origList and offsetAmount
cout<<offsetAmount[i]+origList[i]<<" ";
} The iteration ends here
The web development team is having difficulty connecting by ssh to your local web server, and you notice the proper rule is missing from the firewall. What port number would you open on your webserver?
a. Port 21
b. Port 22
c .Port 25
d. Port 80
e. Port 443
Answer:
Option b (Port 22) seems to the appropriate choice.
Explanation:
Below seem to be some measure you should take to correct this mistake.
Verify whether Droplet's host IP address seems to be right. Verify existing connection supports communication over all the utilized SSH port. Any access points can be able to block port 22 and sometimes customized SSH. For illustration, you could do this by checking different hosts who used the same port, using only a recognized working SSH connection. These could help you identify unless the current problem is not particular to clients' Droplet. Authenticate the Droplet configuration settings. Verify that they're not being configured to DROP 's preferred policy, and do not apply the port to require connectivity.The SSH server also operates on port 22, by default.
Other choices don't apply to the specified scenario. So that the argument presented above will be appropriate.
The port number would you open on your webserver is Port 22
For better understanding let's explain SSH means.
Service Name and Transport Protocol Port Number Registry. where the service name is Secure Shell (SSH) Protocol and it has the port number of 22 therefore this mean that SSH will only work with port 22 using it for other port will only result in difficulty in connection. SSH has other names like Secure Shell or Secure Socket Shell. it is known as a network protocol that helps its users with system administrator.From the above we can therefore say that the answer The port number would you open on your webserver is Port 22, is correct

A TCP entity opens a connection and uses slow start. Approximately how many round-trip times are required before TCP can send N segments
Answer:
Round trip times required = log2N
Explanation:
The round-trip times required before TCP can send N segments using a slow start is log2N. we can arrive at this by looking at the mode of operation of TCP which is at the 1st time of using a TCP it starts the congestion window as 1 then it sends an initial segment. When the acknowledgement of the initial segment arrives, TCP increases the congestion window to 2 and then sends 2 segments, When the 2 acknowledgements of the segments sent out arrives, they each increase the congestion window by one, thereby increasing the congestion window to 4 . therefore it takes log2N round trips before TCP can send N segments

person1 = Person("David Joyner", 30, 901234567)
person2 = Person("D. Joyner", 29, 901234567)
person3 = Person("David Joyner", 30, 903987654)
print(same_person(person1, person2))
print(same_person(person1, person3))
Answer:
Here is the function same_person that takes two instances of Person as arguments i.e. p1 and p2 and returns True if they are the same Person, False otherwise.
def same_person(p1, p2): #definition of function same_person that takes two parameters p1 and p2
if p1.GTID==p2.GTID: # if the two instances of Person have same GTID
return True #returns true if above condition evaluates to true
else: #if the two instances of Person do not have same GTID
return False #returns false when two persons have different GTID
Explanation:
person1 = Person("David Joyner", 30, 901234567) #first instance of Person
person2 = Person("D. Joyner", 29, 901234567) #second instance of Person
person3 = Person("David Joyner", 30, 903987654) #third instance of Person
print(same_person(person1, person2)) #calls same_person method by passing person1 and person2 instance of Person to check if they are same
print(same_person(person1, person3)) #calls same_person method by passing person1 and person3 instance of Person to check if they are same
The function works as follows:
For function call print(same_person(person1, person2))
The GTID of person1 is 901234567 and that of person2 is 901234567
If condition if p1.GTID==p2.GTID in the function same_person checks if the GTID of person1 is equal to the GTID of person2. This condition evaluates to true because GTID of person1 = 901234567 and GTID of person2 = 901234567
So the output is:
True
For function call print(same_person(person1, person3))
The GTID of person1 is 901234567 and that of person3 is 903987654
If condition if p1.GTID==p2.GTID in the function same_person checks if the GTID of person1 is equal to the GTID of person3. This condition evaluates to false because GTID of person1 = 901234567 and GTID of person2 = 903987654 and they are not equal
So the output is:
False

How can technology efforts be reconciled to improve hazard/disaster preparedness, response, and mitigation to insure systems sustainability, data integrity, and supply chain protection?
Answer:
Prediction
With regard to preparedness for hazard/disaster, technology such as AI are being explored to see how they can help to predict natural disaster.
If there is a breakthrough in this space, it will drastically reduce the negative impact of natural disasters such as floods and earthquakes as people will become ready to respond to them and mitigate their effects where possible.
In agriculture, there are factors which come together to bring about flooding. Flooding is one of the major disasters which cripples entire value chains. With a potential threat anticipated or predicted by AI, businesses can invest in technologies that can help protect the farms, farmland and other resources critical to such a supply chain.
AI-powered technologies that provide prediction services often combine this advanced computing prowess with the ability to process big data.
Technology can reach places that are unreachable by humans
AI-powered robots will soon become the norm.
Presently there are self-learning and self instructing robots powered by Artificial Intelligence that have applications in warfare, manufacturing, deepsea diving and intelligence gathering, and transportation. It is not out of place to predict that in the next decade, scientists would have perfected rescue robots that can go into very unstable terrain that have been damaged by flood or earthquake and attempt a rescue of lives and property at a scale that has never been possible before.
Connectivity
Connectivity helps people access to aid, resources that are critical for survival, transmission and receipt of life--saving information etc. CISCO has successfully used its technology called TacOps (short for Tactical Operations) successfully 45 times on over 5 continents.

In using cloud infrastructures, the client necessarily cedes control to the CP on a number of issues that may affect security
a. True
b. False
Answer:
A. True
Explanation:
The correct option is A. True.
Actually, in using cloud infrastructures, the client necessarily cedes control to the CP on a number of issues which may affect security. It may have to restrict port scans and even penetration testing. Moreover, the service level agreements may not actually guarantee commitment to offer such services on the part of the CP. This may result in leaving a gap in security defenses.
Also, when the control of the CP changes, it's evident that the terms and conditions of their services may also change which may affect security.
Given an integer n and an array a of length n, your task is to apply the following mutation to a:
Array a mutates into a new array b of length n.
For each i from 0 to n - 1, b[i] = a[i - 1] + a[i] + a[i + 1].
If some element in the sum a[i - 1] + a[i] + a[i + 1] does not exist, it should be set to 0. For example, b[0] should be equal to 0 + a[0] + a[1].
Example
For n = 5 and a = [4, 0, 1, -2, 3], the output should be mutateTheArray(n, a) = [4, 5, -1, 2, 1].
b[0] = 0 + a[0] + a[1] = 0 + 4 + 0 = 4
b[1] = a[0] + a[1] + a[2] = 4 + 0 + 1 = 5
b[2] = a[1] + a[2] + a[3] = 0 + 1 + (-2) = -1
b[3] = a[2] + a[3] + a[4] = 1 + (-2) + 3 = 2
b[4] = a[3] + a[4] + 0 = (-2) + 3 + 0 = 1
So, the resulting array after the mutation will be [4, 5, -1, 2, 1].
Input/Output

An integer representing the length of the given array.
Guaranteed constraints:
1 ≤ n ≤ 103.
[input] array.integer a
An array of integers that needs to be mutated.
Guaranteed constraints:
a.length = n,

Answer:
The program written in Java is as follows
import java.util.Scanner;
public class mutilate {
public static void main(String [] args) {
Scanner input = new Scanner(System.in);
int n;
System.out.print("Array Length: ");
n = input.nextInt();
while(n<1 || n > 103) {
System.out.print("Array Length: ");
n = input.nextInt();
}
int a []= new int [n];
int b []= new int [n];
System.out.print("Enter Elements of the Array: ");
for(int i =0;i<n;i++) {
a[i] = input.nextInt();
}
System.out.print("Output: ");
for(int i =0;i<n;i++) {
if(i == 0) {
b[i] = 0+a[i]+a[i+1];
}
else if(i == n-1) {
b[i] = a[i - 1]+a[i]+0;
}
else {
b[i] = a[i - 1]+a[i]+a[i+1];
}
System.out.print(b[i]+" ");
}
}
}
Explanation:
This line allows the program accepts user input
Scanner input = new Scanner(System.in);
This line declares integer n
int n;
The next two line prompts user for length of the array and also accepts input
System.out.print("Array Length: ");
n = input.nextInt();
The following while iteration ensures that the user input is between 1 and 103
while(n<1 || n > 103) {
System.out.print("Array Length: ");
n = input.nextInt();
}
The next two lines declares array a and b
int a []= new int [n];
int b []= new int [n];
The next for iteration allows user enter values for array a
System.out.print("Enter Elements of the Array: ");
for(int i =0;i<n;i++) {
a[i] = input.nextInt();
}
The next for iteration calculates and prints the values for array b based on the instruction in the question
System.out.print("Output: ");
for(int i =0;i<n;i++) {
if(i == 0) {
b[i] = 0+a[i]+a[i+1];
}
else if(i == n-1) {
b[i] = a[i - 1]+a[i]+0;
}
else {
b[i] = a[i - 1]+a[i]+a[i+1];
}
System.out.print(b[i]+" ");
}

Answer:
The answer is "0 to 4294967295"
Explanation:
Given bit:
32 bits
Calculating smallest and largest bits:
In any processor, it works only on the 0 and 1 bit and it also stores 0 and 1 values. so, the smallest address in bit value is= 0 and the largest bit value can be defined as follows:
largest address value in bits:
[tex]\Longrightarrow 2^{32}-1\\\\\Longrightarrow 4294967296 -1\\\\\Longrightarrow 4294967295\\\\[/tex]
smallest address= 0
largest address = 4294967295

12. advanced
Answer:
a) An ARRAY ( 3 )
B) relatively INSENSITIVE ( 7 )
c) a HYBRID ( 4 )
Explanation:
They both used an array based implementation in the standard form and are both relatively insensitive to the order of the data. The main similarity is that each one creates an environment in which a hybrid strategy works more efficiently.
Quadratic selection sort is the sorting system that sorts out the smallest value in an entire list and arrange the list in such a way that the smallest value comes first.
#Recall that input from a user is always in the form of a string. #Write a function called "input_type" that gets user input and #determines what kind of string the user entered. The user input #will be supplied as an argument to the function like normal. # # - Your function should return "integer" if the string only # contains characters 0-9. # - Your function should return "float" if the string only # contains the numbers 0-9 and at most one period. # - You should return "boolean" if the user enters "True" or # "False". # - Otherwise, you should return "string". #Write your function here!
Answer:
Here is the Python program:
def input_type(input_string): #function that takes a string as input and returns the type of that string
try: #used to test a block of code for input string type
if type(eval(input_string)) == float: #if the type of the string is float
return "float" #function returns float
elif type(eval(input_string)) == int: #else if the type of the string is int
return "integer"#function return integers
elif type(eval(input_string)) == bool:#else if the type of the string is bool
return "boolean" #function return boolean
except: #if the type of the string is neither int, bool nor float
return "string" #function return boolean
#following statements are used to test the working of the above function
print(input_type(" ")) #prints string
print (input_type ("False")) #prints boolean
print (input_type ("7.432621")) #prints float
print (input_type("2788"))#prints int
Explanation:
The function input_type() takes a user input and returns the type of that string input the user entered. The user input can be one of the following types:
int which is the data type of an integer for example 1, 2, 3 etc
float which is the data type of a floating point number for example 1.2, 3.4 etc
bool which is the data type of a boolean for example True or False
string that can be characters for example an empty space character " "
try block here is used to generate an exception and it is used to test a block in the code that checks for the type of the user input. The except block here is used to handle that error. This is executed when the try part raises an error.
Inside the try block, the if and elif statements check the type of the string.
if type(eval(input_string)) == float: statement checks if the type of the string is float. Here the eval() method is used to convert the input string because the user input is basically a string value. So this method evaluates the input_string.
type() method is used to return the type of that evaluated user input string. If condition checks if type(eval(input_string)) which is the type of the evaluated input string is equal to float. If this condition evaluates to true then the function returns "float" otherwise it moves to the next elif statement. Similarly the type of the user input is checked for int in elif part and if both these if and elif conditions evaluate to false then the next elif statement is executed that checks the user input to be bool. If all these three if elif statements evaluate to false then the except part executes which returns "string". The program along with its output is attached in a screenshot.
