Answer:
The programming language is not stated; However, the program written in C++ is as follows: (See Attachment)
#include<iostream>
using namespace std;
string capt(string result)
{
result[0] = toupper(result[0]);
for(int i =0;i<result.length();i++){
if(result[i]=='.' || result[i]=='?' ||result[i]=='!') {
if(result[i+1]==' ') {
result[i+2] = toupper(result[i+2]);
}
if(result[i+2]==' ') {
result[i+3] = toupper(result[i+3]);
}
} }
return result;
}
int main(){
string sentence;
getline(cin,sentence);
cout<<capt(sentence);
return 0;
}
Explanation:
The method to capitalize first letters of string starts here
string capt(string result){
This line capitalizes the first letter of the sentence
result[0] = toupper(result[0]);
This iteration iterates through each letter of the input sentence
for(int i =0;i<result.length();i++){
This checks if the current character is a period (.), a question mark (?) or an exclamation mark (!)
if(result[i]=='.' || result[i]=='?' ||result[i]=='!') {
if(result[i+1]==' '){ ->This condition checks if the sentence is single spaced
result[i+2] = toupper(result[i+2]);
-> If both conditions are satisfied, a sentence is detected and the first letter is capitalized
}
if(result[i+2]==' '){ ->This condition checks if the sentence is double spaced
result[i+3] = toupper(result[i+3]);
-> If both conditions are satisfied, a sentence is detected and the first letter is capitalized
}
}
} The iteration ends here
return result; ->The new string is returned here.
}
The main method starts here
int main(){
This declares a string variable named sentence
string sentence;
This gets the user input
getline(cin,sentence);
This passes the input string to the method defined above
cout<<capt(sentence);
return 0;
}
A user in an apartment building on a wireless network is no longer able to print to the network printer. 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.

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.

Using virtualization comes with many advantages, one of them being performance. Which of these is NOT another realistic advantage of using virtualization over dedicated hardware?a. There are improvements in security and high availability during outage.b. There are cost benefits.c. Maintenance and updates are simplified or eliminated.d. There are fewer points of failure.
Answer:
a. There are improvements in security and high availability during outage
Explanation:
Virtualization occurs when data that could be in several formats (for example, storage devices) are made to appear real through a software. There are virtualization providers who act as third-party between users and the original manufacturers of the software. While virtualization has received wide popularity in recent times because of the several advantages it offers of which cost-saving is included, it also has some disadvantages. One of them from the options provided is the possibility of a security breach and its uncertain availability.
The security breach arises because of the proliferation of information on the virtual space. This information can be accessed by unauthorized hackers. Also since third-party providers are the usual providers of virtualization services, the availability depends on them because if they shut down, users can no longer access the software.
Which branch structure does a program use to output "Yes" if a variable's value is positive, or "No" otherwise?
Answer:
Selection control structure
Explanation:
This is often referred to as if-conditional statement;
This condition tests for a condition and performs a sequence of operation depending on the result of the condition;
Take for instance, the following program written in python
x = int(input("enter any number: "))
if x < 0:
print("Yes")
else
print("No")
The above checks if the input number is less than 0,
If the condition is true, it prints Yes
If otherwise, it prints No

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

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

If the data rate is 10 Mbps and the token is 64 bytes long (the 10-Mbps Ethernet minimum packet size), what is the average wait to receive the token on an idle network with 40 stations? (The average number of stations the token must pass through is 40/2 = 20.) Ignore the propagation delay and the gap Ethernet requires between packets.
Answer:
1.024x10^-5
Explanation:
To calculate the transmission delay bytes for the token,
we have the token to be = 64bytes and 10mbps rate.
The transmission delay = 64bytes/10mbps
= 51.2 microseconds
A microsecond is a millionth of a second.
= 5.12 x 10^-5
The question says the average number of stations that the token will pass through is 20. Remember this value is gotten from 40/2
20 x 5.12 x 10^-5
= 0.001024
= 1.024x10^-5
Therefore on an idle network with 40 stations, the average wait is
= 1.024x10^-5

Explanation:
Consider two different processors P1 and P2 executing the same instruction set. P1 has a 3 GHz clock rate and a CPI of 1.5. P2 has a 3 GHz clock rate and a CPI of 1.0. Which processor has the highest performance expressed in instructions per second
Answer:
Processor P2 has the highest performance expressed in instructions per second.
Explanation:
Given:
Processors:
P1
P2
Clock rate of P1 = 3 GHz
Clock rate of P2 = 3 GHz
Cycles per instruction = CPI of P1 = 1.5
Cycles per instruction = CPI of P2 = 1.0
To find:
which processor has the highest performance in instructions per second (IPS)
Solution:
Compute CPU time:
CPU time = (Number of instructions * cycles per instruction) / clock rate
CPU time = (I * CPI) / R
We are given the CPI and clock rate. So
CPU time = (I * CPI) / R
I / CPU time = R/CPI
Since
Instructions per second = Number of instructions (I) / execution time
IPS = I / CPU time
So
Instructions Per Second = clock rate / cycles per instruction
IPS = R/CPI
Putting the values in above formula:
Instructions Per Second for P1 = IPS (P1)
= clock rate P1 / CPI (P1)
= 3 GHz / 1.5
IPS (P1) = 2
As 1 GHz = 10⁹ Hz
IPS (P1) = 2x10⁹
Instructions Per Second for P2 = IPS (P2)
= clock rate P2 / CPI (P2)
= 3 / 1.0
IPS (P2) = 3
As 1 GHz = 10⁹ Hz
IPS (P2) = 3x10⁹
Hence processor P2 has the highest performance expressed in instructions per second i.e. 3x10⁹

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 */
printf("sumExtra: %d\n", sumExtra);
return 0;
}
4)Write a for loop to print all NUM_VALS elements of array hourlyTemp. Separate elements with a comma and space. Ex: If hourlyTemp = {90, 92, 94, 95}, print:
90, 92, 94, 95
Note that the last element is not followed by a comma, space, or newline.
#include
int main(void) {
const int NUM_VALS = 4;
int hourlyTemp[NUM_VALS];
int i = 0;
hourlyTemp[0] = 90;
hourlyTemp[1] = 92;
hourlyTemp[2] = 94;
hourlyTemp[3] = 95;
/* Your solution goes here */
printf("\n");
return 0;
}
Answer:
1)
for(i = 0; i < NUM_VALS; ++i) {
if(userValues[i] == matchValue) {
numMatches++; } }
2)
for (i = 0; i < NUM_GUESSES; i++) {
scanf("%d", &userGuesses[i]); }
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.
