Explanation:
Javascript is a multi-purpose programming language, used in applications like web development, software development and embedded system programming, data visualization and analysis, etc.
Its regular syntax defines variables with the "var" keyword and with additional ecmascript rules, the "let" and "const" keywords as well. function definition uses the keyword "function" with parenthesis for holding arguments. The code block of a function is written between two curly braces and returns a value stored in a variable with the return keyword.
The variable can now be called with the parenthesis and required arguments. Note that only anonymous functions can assigned to a variable.

You bought a monochrome laser printer two years ago. The printer has gradually stopped feeding paper. Which printer component should you check first
Answer:
Pick up roller
Explanation:
you should first check the pickup roller component. This component is the part of the printer that picks paper up from the paper tray. The pickup roller links the printer and the paper. When the printer printer is running, the roller would take paper from the paper tray for the printer to print on. One of the issues it can have is Paper jam where the roller would stop turning so that it will no longer be picking papers up from the tray.

Consider a bit stuffing framing method where the start of a frame is indicated by 6 consecutive ones, followed by 2 zeroes. What should be the bit stuffing rules at the transmitter? What should be the bit destuffing rules at the receiver? Fill in the blank to show what is the stream after bit stuffingWrite the rule for stuffing:Write the rule for destuffing:Assume the user data stream before bit stuffing is 011111100011111101. What is the stream after bit stuffing?
Answer:
Explanation:
Bit stuffing Framing Method
In the given situation, the beginning casing is shown by 6 sequential ones followed by 2 zeroes.
The beginning casings are generally known as the flags.which are utilized for demonstrating the beginning and end of the edges. Essentially utilized for the synchronization between the sender and the reciever.
Along these lines here the beginning and end banners are 11111100(this is on the grounds that the end banner is same as the beginning banner).
To enable us understand how this question plays out, let us understand the rule for Stuffing and De-stuffing .
The standard for stuffing is :
At whatever point there are 5 successive ones supplement one zero in the casing which is an information. The embedded zero piece is known as the stuffed bit.The principle reason behind stuffing somewhat after 5 back to back ones is to evade the distortion of information (data) as flag. If the reciever misconstrues the information as end banner then he would quit recieving the information where the entire information sent by the sender will be left and lost causing an error-prone information.
The rule for destuffing :
The standard/rule for destuffing is only inverse as stuffing. After recieving the bitstuffed information (data), at the reciever's end zero after each 5 continuous ones will be evacuated and the rest of the information will be considered as the genuine information.
In the given situation, the beginning casing is demonstrated by 6 back to back ones followed by 2 zeroes.
the beginning casings are normally known as the flags.which are utilized for showing the beginning and end of the edges. Essentially utilized for the synchronization between the sender and the receiver.
In this way here the beginning and end banners are 11111100(this is on the grounds that the end banner is same as the beginning banner).
data before bit stuffing is: 011111100011111101the stream after stuffing would be: 01111101000111101101where the bolded/underlined digits represents the stuffed bits

________ databases are better than relational databases at handling unstructured data such as audio clips, video clips, and pictures.
Answer:
"Object-oriented" would be the correct choice.
Explanation:
An object-oriented database seems to be a database that subscribes to a framework containing object-depicted details. Throughout the context of the relational database management system, object-oriented is a unique product that is not as popular and most well-known as traditional web applications.This indicates that internet connectivity to existing records has to implement the previously defined connections for interacting components established by that same containers.An organization is planning to implement a VPN. They want to ensure that after a VPN client connects to the VPN server, all traffic from the VPN client is encrypted. Which of the following would BEST meet this goal?a. Split tunnelb. Full tunnelc. IPsec using Tunnel moded. IPsec using Transport mode
Answer:
B. Full tunnel.
Explanation:
In this scenario, an organization is planning to implement a virtual private network (VPN). They want to ensure that after a VPN client connects to the VPN server, all traffic from the VPN client is encrypted. The best method to meet this goal is to use a full tunnel.
A full tunnel is a type of virtual private network that routes and encrypts all traffics or request on a particular network. It is a bidirectional form of encrypting all traffics in a network.
On the other hand, a split tunnel is a type of virtual private network that only encrypts traffic from the internet to the VPN client.
Hence, the full tunnel method is the most secured type of virtual private network.

Set numMatches to the number of elements in userValues (having NUM_VALS elements) that equal matchValue. Ex: If matchValue = 2 and userVals = {2, 2, 1, 2}, then numMatches = 3.
#include
int main(void) {
const int NUM_VALS = 4;
int userValues[NUM_VALS];
int i = 0;
int matchValue = 0;
int numMatches = -99; // Set numMatches to 0 before your for loop
userValues[0] = 2;
userValues[1] = 2;
userValues[2] = 1;
userValues[3] = 2;
matchValue = 2;
/* Your solution goes here */
printf("matchValue: %d, numMatches: %d\n", matchValue, numMatches);
return 0;
}
2)Write a for loop to populate array userGuesses with NUM_GUESSES integers. Read integers using scanf. Ex: If NUM_GUESSES is 3 and user enters 9 5 2, then userGuesses is {9, 5, 2}.
#include

int userGuesses[NUM_GUESSES];
int i = 0;
/* Your solution goes here */

}
3)Array testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107, 90}, then sumExtra = 8, because 1 + 0 + 7 + 0 is 8.
#include
int main(void) {
const int NUM_VALS = 4;
int testGrades[NUM_VALS];
int i = 0;
int sumExtra = -9999; // Initialize to 0 before your for loop
testGrades[0] = 101;
testGrades[1] = 83;
testGrades[2] = 107;
testGrades[3] = 90;
/* Your solution goes here */

for (i = 0; i < NUM_GUESSES; ++i) {
printf("%d ", userGuesses[i]); }
3)
sumExtra = 0;
for (i = 0; i < NUM_VALS; ++i){
if (testGrades[i] > 100){
sumExtra = testGrades[i] - 100 + sumExtra; } }
4)
for (i = 0; i < NUM_VALS; ++i) {
if (i<(NUM_VALS-1))
printf( "%d,", hourlyTemp[i]);
else
printf("%d",hourlyTemp[i]); }
Explanation:
1) This loop works as follows:
1st iteration:
i = 0
As i= 0 and NUM_VALS = 4 This means for condition i<NUM_VALS is true so the body of loop executes
if(userValues[i] == matchValue) condition checks if element at i-th index position of userValues[] array is equal to the value of matchValue variable. As matchValue = 2 and i = 0 So the statement becomes:
userValues[0] == 2
2 == 2
As the value at 0th index (1st element) of userValues is 2 so the above condition is true and the value of numMatches is incremented to 1. So numMatches = 1
Now value of i is incremented to 1 so i=1
2nd iteration:
i = 1
As i= 1 and NUM_VALS = 4 This means for condition i<NUM_VALS is true so the body of loop executes
if(userValues[i] == matchValue) condition checks if element at i-th index position of userValues[] array is equal to the value of matchValue variable. As matchValue = 2 and i = 1 So the statement becomes:
userValues[1] == 2
2 == 2
As the value at 1st index (2nd element) of userValues is 2 so the above condition is true and the value of numMatches is incremented to 1. So numMatches = 2
Now value of i is incremented to 1 so i=2
The same procedure continues at each iteration.
The last iteration is shown below:
5th iteration:
i = 4
As i= 4 and NUM_VALS = 4 This means for condition i<NUM_VALS is false so the loop breaks
Next the statement: printf("matchValue: %d, numMatches: %d\n", matchValue, numMatches); executes which displays the value of
numMatches = 3
2)
The first loop works as follows:
At first iteration:
i = 0
i<NUM_GUESSES is true as NUM_GUESSES = 3 and i= 0 so 0<3
So the body of loop executes which reads the element at ith index (0-th) index i.e. 1st element of userGuesses array. Then value of i is incremented to i and i = 1.
At each iteration each element at i-th index is read using scanf such as element at userGuesses[0], userGuesses[1], userGuesses[2]. The loop stops at i=4 as i<NUM_GUESSES evaluates to false.
The second loop works as follows:
At first iteration:
i = 0
i<NUM_GUESSES is true as NUM_GUESSES = 3 and i= 0 so 0<3
So the body of loop executes which prints the element at ith index (0-th) index i.e. 1st element of userGuesses array. Then value of i is incremented to i and i = 1.
At each iteration, each element at i-th index is printed on output screen using printf such as element at userGuesses[0], userGuesses[1], userGuesses[2] is displayed. The loop stops at i=4 as i<NUM_GUESSES evaluates to false.
So if user enters enters 9 5 2, then the output is 9 5 2
3)
The loop works as follows:
At first iteration:
i=0
i<NUM_VALS is true as NUM_VALS = 4 so 0<4. Hence the loop body executes.
if (testGrades[i] > 100 checks if the element at i-th index of testGrades array is greater than 100. As i=0 so this statement becomes:
if (testGrades[0] > 100
As testGrades[0] = 101 so this condition evaluates to true as 101>100
So the statement sumExtra = testGrades[i] - 100 + sumExtra; executes which becomes:
sumExtra = testGrades[0] - 100 + sumExtra
As sumExtra = 0
testGrades[0] = 101
So
sumExtra = 101 - 100 + 0
sumExtra = 1
The same procedure is done at each iteration until the loop breaks. The output is:
sumExtra = 8
4)
The loop works as follows:
At first iteration
i=0
i < NUM_VALS is true as NUM_VALS = 4 so 0<4 Hence loop body executes.
if (i<(NUM_VALS-1)) checks if i is less than NUM_VALS-1 which is 4-1=3
It is also true as 0<3 Hence the statement in body of i executes
printf( "%d,", hourlyTemp[i]) statement prints the element at i-th index i.e. at 0-th index of hourlyTemp array with a comma (,) in the end. As hourlyTemp[0] = 90; So 90, is printed.
When the above IF condition evaluates to false i.e. when i = 3 then else part executes which prints the hourlyTemp[3] = 95 without comma.
Same procedure happens at each iteration unless value of i exceeds NUM_VAL.
The output is:
90, 92, 94, 95
The programs along with their output are attached.

1. Cases Prudence has a special (cubic) die. The values on its face are the integers from 1 to 6, but they are not arranged ae in a normal die. When Prudence first tosses the die, the sum of the values on the four side faces is 15. In her second toss, the sum of these values is 12. Find what value appears in the face opposite 6 on Prudence’s special die. (Hint: what are possible values for the top and bottom face when the sum of the side faces is 12).
Answer:
The definition of the subject in question is presented in section elsewhere here.
Explanation:
The total value of almost all of the quantities mostly on unique die features will indeed be:
⇒ [tex]1+2+3+4+5+6[/tex]
⇒ [tex]21[/tex]
The number of the 4 lateral sides throughout the first tossing will be 15, therefore determines the total of both top and bottom features would be:
⇒ [tex]21-15[/tex]
⇒ [tex]6[/tex]
The compositions including its {top and bottom} current valuations that give a total of Six include {1, 5}, {5, 1}, {2, 4}, as well as {4, 2}. Consequently, because neither of those variations includes Six, it indicates that six doesn't really feature on the very first toss mostly on high or low hand.
And then let's look at second tossed situation. Throughout this particular instance, the total amount obtained would be 12.
Which means it has to be the number of top and bottom:
⇒ [tex]21-12[/tex]
⇒ [tex]9[/tex]
{4, 5},{5, 4}, {6, 3}, and {3, 6} seem to be the {top, bottom} facial variations that provide a total of Nine.
Currently regarding all the tosses, {6, 3} and perhaps {3, 6} have been the only situations wherein the 6 emerge towards top or bottom. Then the value of the unique die mostly on face identical to 6 must've been 3.

The user has been able to print to the printer in the past and nothing on the network has changed. A technician notices that the user has a different IP address scheme than what was originally setup and is able to browse the Internet using that IP address scheme. What should he do?
Answer:
The technician should either provide a route from the user's IP scheme to the printer or change the user's IP scheme to be within the same scheme as the printer.
Explanation:
The most likely reason the user is unable to print to the printer is that the user's computer cannot path the current address to the address of the printer. Without the printer being on the same subnet as the user's computer, the computer has no way of being able to tell where the printer is.
The two solutions to this are to either add a route to the user's computer explicitly telling the user's computer where to trace to find the printer or to change the user's computer to match the IP scheme of the printer.

Explanation:
You were very close. Use the standard <stack> STL library, and make sure the stack elements are of the same type as what you're trying to add, i.e., std::string.
#Below is a class representing a person. You'll see the
#Person class has three instance variables: name, age,
#and GTID. The constructor currently sets these values
#via a calls to the setters.
#
#Create a new function called same_person. same_person
#should take two instances of Person as arguments, and
#returns True if they are the same Person, False otherwise.
#Two instances of Person are considered to be the same if
#and only if they have the same GTID. It does not matter
#if their names or ages differ as long as they have the
#same GTID.
#
#You should not need to modify the Person class.
class Person:
def __init__(self, name, age, GTID):
self.set_name(name)
self.set_age(age)
self.set_GTID(GTID)
def set_name(self, name):
self.name = name
def set_age(self, age):
self.age = age
def set_GTID(self, GTID):
self.GTID = GTID
def get_name(self):
return self.name
def get_age(self):
return self.age
def get_GTID(self):
return self.GTID
#Add your code below!
#Below are some lines of code that will test your function.
#You can change the value of the variable(s) to test your
#function with different inputs.
#
#If your function works correctly, this will originally
#print: True, then False.
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

Explain how Deep Packet Inspection works (DPI). How is this technology beneficial to Perimeter Security? Lastly, describe a scenario where the use of DPI may be considered a privacy concern.
Answer:
Answered below
Explanation:
Deep packet inspection is a kind of data processing that thoroughly inspects data sent over a computer network and acts on it by rerouting, logging or blocking it. Uses of DPI include;
To ensure that data is in the correct format, internet censorship, to check for malicious code, and also eavesdropping.
DPI uses port mirroring and optical splitter to acquire packets for inspection. It combines the functionality of an intrusion detection system and intrusion prevention system with a traditional stateful firewall.
DPI is therefore helpful in perimeter security by keeping unauthorized users out and at the same time protecting authorized users from attack. Privacy concerns have been raised over the inspection of content layers of internet protocols such as in the case of censorship and government regulations and control.
