Answer:
a) Pick ONE OR MORE options Using code-splitting for JS files.
b) Compressing the JS files on the server-side
Explanation:
Javascript is a multi-purpose programming language, it is used in web development as a scripting language for programming the interactiveness of the web application.
Loading and running the script from the server can take a lot of time, so, the file is compressed and split for faster loading.
Answer:
import java.util.Scanner;
public class Speed{
int speed;
public Speed(int speed){
this.speed = speed;
}
public void checkSpeed(){
if(speed >= 24 || speed <= 56){
System.out.println("Speed is normal");
}
else
System.out.println("Speed is abnormal");
}
public static void main(String...args){
Scanner input = new Scanner(System.in);
int userSpeed = 0;
System.out.println("Enter a speed: ");
userSpeed = input.nextInt();
Speed obj1 = new Speed(userSpeed)
obj1.checkSpeed();
}

Answer:
- import random
-
- states = {
- "Alabama": "Montgomery",
- "California": "Sacramento",
- "Florida": "Tallahassee",
- "Hawaii": "Honolulu",
- "Indiana": "Indianapolis",
- "Michigan": "Lansing",
- "New York": "Albany",
- "Texas" : "Austin",
- "Utah" : "Salt Lake City",
- "Wisconsin": "Madison"
- }
-
- correct = 0
- wrong = 0
- round = 1
- while(round <= 5):
- current_state = random.choice(list(states))
- answer = input("What is the capital of " + current_state + ": ")
-
- if(answer == states[current_state]):
- correct += 1
- else:
- wrong += 1
-
- round += 1
-
- print("Correct answer: " + str(correct))
- print("Wrong answer: " + str(wrong))
Explanation:
The solution code is written in Python 3.
Line 3 -14
Create a dictionary of US States with capital as each of their corresponding value. Please note only ten sample states are chosen here.
Line 16 - 18
Create variables to track the number of correct and inaccurate response and also round counter.
Line 19 - 28
Set the while condition to enable user to play the quiz for five questions and use random.choice to randomly pick a state from the dictionary and prompt user to input the capital of selected stated.
If the answer matched with the capital value of the selected state, increment the correct counter by one. Otherwise the wrong counter will be incremented by one. Increment the round counter by one before proceed to next round.
Line 30 - 31
Print the number of correct responses and wrong responses.
Answer:
d. Port mirror
Explanation:
Port mirroring is a method to monitor network traffic and it is used in the Intrusion Detection Systems. It is also called Switched Port Analyzer and is used to analyse the network errors. This technique basically copies the network packets and sends or transmits these copied packed from one port to another in a network device such as a switch. This means that this technique is used to copy the network packets from one switch port and send the copy of these packets to another port where these packets are monitored. This is how it analyses the network errors and incoming traffic for irregular behavior and also this can be done without affecting the normal operation of the switch and other network processes. It is simple, inexpensive and easy to establish and use. The most important advantage of using mirrored ports is that it catches the traffic on several ports at once or can capture all of the network traffic.
Answer:
Correct code for the above question which is written after the defined list to display the output.
for x,y in country_pop.items(): #for loop to prints the list items.
print(str(x)+" has "+str(y)+" people") #print function to print the value.
Output:
- The above code is in python language which display the output as the above question demands.
Explanation:
- The above question code is written in python language to display the result, but this code is not correct.
- The above code needs a 'for' loop, which will render the list item one by one.
- The above-list defined in the form of key-value pair, So there is a need for the ''item" function which is the part of the python dictionary to display the list items.
- There also needs to define the two variables in the for loop, one is for key and the other is for value.
