Christina has been asked by the firewall administration group to identify secure network protocols that can be used to prevent network analyzers from being able to read data in flight. What are considered as secure network protocols?
Answer:
SSH, HTTPS and SMTP
Explanation:
Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Hence, SSH, HTTPS and SMTP are considered as secure network protocols.
HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).
SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.

Read integers from input and store each integer into a vector until -1 is read. Do not store -1 into the vector. Then, output all values in the vector (except the last value) with the last value in the vector subtracted from each value. Output each value on a new line. Ex: If the input is -46 66 76 9 -1, the output is:
-55
57
67
Answer:
The program in C++ is as follows:
#include <iostream>
#include <vector>
using namespace std;
int main(){
vector<int> nums;
int num;
cin>>num;
while(num != -1){
nums.push_back(num);
cin>>num; }
for (auto i = nums.begin(); i != nums.end(); ++i){
cout << *i <<endl; }
return 0;
}
Explanation:
This declares the vector
vector<int> nums;
This declares an integer variable for each input
int num;
This gets the first input
cin>>num;
This loop is repeated until user enters -1
while(num != -1){
Saves user input into the vector
nums.push_back(num);
Get another input from the user
cin>>num; }
The following iteration print the vector elements
for (auto i = nums.begin(); i != nums.end(); ++i){
cout << *i <<endl; }

Given two regular expressions r1 and r2, construct a decision procedure to determine whether the language of r1 is contained in the language r2; that is, the language of r1 is a subset of the language of r2.
Answer:
Test if L(M1-2) is empty.
Construct FA M2-1 from M1 and M2 which recognizes the language L(>M2) - L(>M1).
COMMENT: note we use the algorithm that is instrumental in proving that regular languages are closed with respect to the set difference operator.
Test if L(M2-1) is empty.
Answer yes if and only if both answers were yes.
Explanation:
An algorithm must be guaranteed to halt after a finite number of steps.
Each step of the algorithm must be well specified (deterministic rather than non-deterministic).
Three basic problems:
Given an FA M and an input x, does M accept x?
Is x in L(M)
Given an FA M, is there a string that it accepts?
Is L(M) the empty set?
Given an FA M, is L(M) finite?
Algorithm for determining if M accepts x.
Simply execute M on x.
Output yes if we end up at an accepting state.
This algorithm clearly halts after a finite number of steps, and it is well specified.
This algorithm is also clearly correct.
Testing if L(M) is empty.
Incorrect "Algorithm"
Simulate M on all strings x.
Output yes if and only if all strings are rejected.
The "algorithm" is well specified, and it is also clearly correct.
However, this is not an algorithm because there are an infinite number of strings to simulate M on, and thus it is not guaranteed to halt in a finite amount of time.
COMMENT: Note we use the algorithm for the first problem as a subroutine; you must think in this fashion to solve the problems we will ask.
Correct Algorithm
Simulate M on all strings of length between 0 and n-1 where M has n states.
Output no if and only if all strings are rejected.
Otherwise output yes.
This algorithm clearly halts after a finite number of steps, and it is well specified.
The correctness of the algorithm follows from the fact that if M accepts any strings, it must accept one of length at most n-1.
Suppose this is not true; that is, L(M) is not empty but the shortest string accepted by M has a length of at least n.
Let x be the shortest string accepted by M where |x| > n-1.
Using the Pumping Lemma, we know that there must be a "loop" in x which can be pumped 0 times to create a shorter string in L.
This is a contradiction and the result follows.
COMMENT: There are more efficient algorithms, but we won't get into that.
Testing if L(M) is finite
Incorrect "Algorithm"
Simulate M on all strings x.
Output yes if and only if there are a finite number of yes answers.
This "algorithm" is well specified and correct.
However, this is not an algorithm because there are an infinite number of strings to simulate M on, and thus it is not guaranteed to halt in a finite amount of time.
COMMENT: Note we again use the algorithm for the first problem as a subroutine.
Correct Algorithm
Simulate M on all strings of length between n and 2n-1 where M has n states.
Output yes if and only if no string is accepted.
Otherwise output no.
This algorithm clearly halts after a finite number of steps, and it is well specified.
The correctness of the algorithm follows from the fact that if M accepts an infinite number of strings, it must accept one of length between n and 2n-1.
This builds on the idea that if M accepts an infinite number of strings, there must be a "loop" that can be pumped.
This loop must have length at most n.
When we pump it 0 times, we have a string of length less than n.
When we pump it once, we increase the length of the string by at most n so we cannot exceed 2n-1. The problem is we might not exceed n-1 yet.
The key is we can keep pumping it and at some point, its length must exceed n-1, and in the step it does, it cannot jump past 2n-1 since the size of the loop is at most n.
This proof is not totally correct, but it captures the key idea.
COMMENT: There again are more efficient algorithms, but we won't get into that.
Other problems we can solve using these basic algorithms (and other algorithms we've seen earlier this chapter) as subroutines.
COMMENT: many of these algorithms depend on your understanding of basic set operations such as set complement, set difference, set union, etc.
Given a regular expression r, is Lr finite?
Convert r to an equivalent FA M.
COMMENT: note we use the two algorithms for converting a regular expression to an NFA and then an NFA to an FA.
Test if L(M) is finite.
Output the answer to the above test.
Given two FAs M1 and M2, is L(M1) = L(M2)?
Construct FA M1-2 from M1 and M2 which recognizes the language L(>M1) - L(>M2).
COMMENT: note we use the algorithm that is instrumental in proving that regular languages are closed with respect to the set difference operator.
Test if L(M1-2) is empty.
Construct FA M2-1 from M1 and M2 which recognizes the language L(>M2) - L(>M1).
COMMENT: note we use the algorithm that is instrumental in proving that regular languages are closed with respect to the set difference operator.
Test if L(M2-1) is empty.
Answer yes if and only if both answers were yes.

Use appropriate method calls from the List ADT to create the following list:
< 4 19 | 23 30 >
You should assume that L is passed to the function as an empty list.
public List buildList(List L)
{
}
Answer:
The complete method is as follows:
public List buildList(List L) {
L.insert(30);
L.insert(23);
L.insert(19);
L.insert(4);
return L; }
Explanation:
To complete the method, we make use of the insert() function.
This inserts elements of the list into list L. However, we have to start from the last element (i.e. in descending order)
So, the explanation is as follows:
L.insert(30); --- This inserts the last element
Continue inserting in descending order
L.insert(23);
L.insert(19);
Until the first list element is inserted
L.insert(4);
This returns the filled list L
return L;

Answer:
6 2 and 0
Explanation:
This algorithm doesn't work if the list is not ordered ascending.
In this example it is not, and indeed the item "1" is never found.
first cycle: first=0, last=12 so midpoint=6
second cycle: first=0, last=5 so midpoint=2
last cycle: first=0, last=1 so midpoint=0
then last is assigned -1 so the while statement is no longer true.
In a paragraph, describe in detail a practical real-world example of where you would implement a singly-linked list and why a singly-linked list is best for this use. Do not list the properties of a singly-linked list....
Rather identify a real-world example or application. If you identify this through research, cite your source.
Answer:
travel
Explanation:
One real world example of a singly-linked list would be travel. Imagine that you want to take a trip to your nearest neighbor state. To do so you would need to take a 2 buses and a train, but you can't just take any or in any order you wish. You first need to take the first bus at your current location, get off at the train station, take that train to the final stop, get off and take the bus to the final destination. Meaning there is a sequence of connected events that you must follow in order to get to your destination and the same opposite sequence of events to get back. This is exactly like a singly-linked list.

In the U.S. fuel efficiency of cars is specified in miles per gallon (mpg). In Europe it is often expressed in liters per 100 km. Write a MATLAB user- defined function that converts fuel efficiency from mpg to liters per 100 km. For the function name and arguments, use Lkm-mpgToLpkm (mpg). The input argument mpg is the efficiency in mi/gl, and the output argument Lkm is the efficiency in liters per 100 km (rounded to the nearest hundredth). Use the function in the Command Window to:________.
(a) Determine the fuel eficiency in liters per 100 km of a car whose fuel effi- ciency is 21 mi/gal.
(b) Determine the fuel efficiency in liters per 100 km of a car whose fuel effi- ciency is 36 mi/gal.
Answer and Explanation:
Using MATLAB code:
Function Lkm = Lkm-mpgToLpkm (mpg)
Lkm= mpg*1.60934/3.78541;
Lkm= Lkm^(-1);
Lkm= Lkm*100;
%the code above defines a function Lkm and takes argument/input to its parameter mpg(miles per gallon) and then returns/output Lkm which is the litres per kilometers conversion from miles per gallon input.
end
To call the function written above with argument 30 mpg, we write:
Lkm= Lkm-mpgToLpkm (30)
Design traffic lights at an intersection of a city. North and South (up and down) are going to be a main highway, East and West (right and left) will be a smaller cross street. There will be no turn signals and no cross walks. You only need to build/code one set of lights for each street (one set of green, yellow, and red for the highway, and another set for the cross street). You do not need to build actual traffic lights or an intersection.
Answer:
Explanation:
The following code is written in Java. In order to code this efficiently, I created a class for the trafficLights. The class contains the currentLight, and the streetType as variables and contains a constructore, getter and setter methods, and a method to turn to the next light in the sequence. Then I created 4 objects of TrafficLights for the highways and the streets.
class Brainly {
public static void main(String[] args) {
TrafficLights highwaySouth = new TrafficLights("Highway", "green");
TrafficLights highwayNorth = new TrafficLights("Highway", "green");
TrafficLights streetEast = new TrafficLights("Street", "yellow");
TrafficLights streetWest = new TrafficLights("Street", "red");
}
}
class TrafficLights {
String streetType, currentLight;
public TrafficLights(String streetType, String currentLight) {
this.streetType = streetType;
this.currentLight = currentLight;
}
public void nextLight() {
if (this.currentLight == "green") {
this.currentLight = "yellow";
} else if (this.currentLight == "yellow") {
this.currentLight = "red";
} else {
this.currentLight = "green";
}
}
public String getStreetType() {
return streetType;
}
public void setStreetType(String streetType) {
this.streetType = streetType;
}
public String getCurrentLight() {
return currentLight;
}
public void setCurrentLight(String currentLight) {
this.currentLight = currentLight;
}
}
