Answer:

It is A: Packet metadata is used to route and reassemble information travelling through the internet.

Explanation:

Step 1: The Internet works by chopping data into chunks called packets. Each packet then moves through the network in a series of hops. Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee

Step 2: Entering the network

Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee.

Step 3: Taking flight

The next hop delivers the packet to a long-haul provider, one of the airlines of cyberspace that quickly carrying data across the world.

Step 4: BGP

These providers use the Border Gateway Protocol to find a route across the many individual networks that together form the Internet.

Step 5: Finding a route

This journey often takes several more hops, which are plotted out one by one as the data packet moves across the Internet.

Step 6: Bad information

For the system to work properly, the BGP information shared among routers cannot contain lies or errors that might cause a packet to go off track – or get lost altogether.

Last step: Arrival

The final hop takes a packet to the recipient, which reassembles all of the packets into a coherent message. A separate message goes back through the network confirming successful delivery.

Answer:

The Java code is given below with appropriate comments for explanation

Explanation:

// java code to contradict birth day paradox

import java.util.Random;

public class BirthDayParadox

{

public static void main(String[] args)

{

Random randNum = new Random();

int people = 5;

int[] birth_Day = new int[365+1];

// setting up birthsdays

for (int i = 0; i < birth_Day.length; i++)

birth_Day[i] = i + 1;

int iteration;

// varying number n

while (people <= 100)

{

System.out.println("Number of people: " + people);

// creating new birth day array

int[] newbirth_Day = new int[people];

int count = 0;

iteration = 100000;

while(iteration != 0)

{

count = 0;

for (int i = 0; i < newbirth_Day.length; i++)

{

// generating random birth day

int day = randNum.nextInt(365);

newbirth_Day[i] = birth_Day[day];

}

// check for same birthdays

for (int i = 0; i < newbirth_Day.length; i++)

{

int bday = newbirth_Day[i];

for (int j = i+1; j < newbirth_Day.length; j++)

{

if (bday == newbirth_Day[j])

{

break;

}

iteration = iteration - 1;

}

System.out.println("Probability: " + count + "/" + 100000);

Python provides a special version of a decision structure known as the ________ statement, which makes the logic of the nested d

IrinaVladis [17]

Answer:

if-elif-else

Explanation:

In Python if condition is used to decide whether a statement or a block of statements is to be executed or not based on the condition, if the condition evaluates to true then the block of statements is executed and if the condition is false then it is not executed.

Sometimes we need to execute some other statement when the condition is false. For example

if (number1 <= number2)

print (number1, "is the smallest")

Lets suppose we want to print another statement if this condition evaluates to false. If the condition gets false then the following message should be displayed:

print(number 2, "is the smallest")

For this purpose else statement is used along with if statement to execute the block of code when the if condition evaluates to false.

if (number1 <= number2)

print (number1, "is the smallest")

else:

print(number 2, "is the smallest")

Now what if there are three numbers or more numbers to be compared in order to identify the smallest number from the given numbers. So in this case we have multiple options to be checked. else statement will not be enough a for else there can be at most one statement. With if elif else multiple conditions can be checked and if any of the condition evaluates to true then its block of code is executed and if none of the condition is true then the last else statement will be executed.

For example:

if (number1 <= number2) and (number1 <= number3):

print (number1, "is the smallest")

elif (number2 <= number1) and (number2 <= number3):

print (number1, "is the smallest")

else:

print (number3, "is the smallest")

In this example number1 is compared to number2 and number3. If both numbers are less than number1 then the program control goes to elif statement where number2 is compared to number1 and number3. if this condition is false too then the final else part will be printed which is that number3 is the smallest.

Take another example where there are more number of expressions to be checked.

val = 50

if (val == 40):

print ("value is 40")

elif (val== 35):

print ("value is 35")

elif (val == 25):

print ("value is 25")

elif(val==15):

print ("value is 15")

else:

print ("value is not present")

This will output the else part value is not present, because none of the condition evaluates to true.

Edit cell B15 to include a formula without a function that divides the total regional sales in Quarter 1 (cell B14) by the numbe

DerKrebs [107]

Answer:

=B14/G2

Explanation:

In cell B15 we would type = to set the value of the cell to the sum of the equation.

Then we have to type in the equation. In this question it is cell B14 divided by cell G2 written like: B14/G2

Then we combine both the = and the equation =B14/G2
