Given that,

Token is 64 bytes long

The average number of stations that the token must pass = 20

We need to calculate the transmission delay for token

Using formula of transmission delay

Transmission\ delay=\dfrac{token\ size}{minimum\ size}

Put the value into the formula

Transmission\ delay=\dfrac{64\ bytes}{10\ Mbps}

Transmission\ delay=\dfrac{64\times8}{10\times10^6}

Transmission\ delay=0.0000512\ sec

Transmission\ delay=5.12\times10^{-5}\ sec

We need to calculate the average wait to receive token on an idle network with 40 stations

Using formula of average wait

\text{average wait to receive token}=\text{average number of stations that the token must pass}\times transmission\ delay

Put the value into the formula

\text{average wait to receive token}=20\times5.12\times10^{-5}

\text{average wait to receive token}= 0.001024\ sec

\text{average wait to receive token}= 1.024\ ms

Hence, The average wait to receive token on an idle network with 40 stations is 1.024 ms.

Define a method printAll() for class PetData that prints output as follows with inputs "Fluffy", 5, and 4444. Hint: Make use of
Vsevolod [243]

Answer and Explanation:

public class petData

{

private int ageYears;

private String fullName;

private int IdNumber;

public void setName (String givenName)

{

fullName = givenName;

return;

}

public void setAge (int numYears)

{

ageYears = numYears;

return;

}

public void setID (int numID)

{

IdNumber = numID;

return;

}

public void printAll ()

{

System.out.print ("Name: " + fullName);

System.out.print (", Age: " + ageYears);

return;

}

}

From the above, we have defined a class petData, with methods setName, setAge, printAll. These methods all make use of the string variable fullName and integer variable ageYears. From the above, setName method sets fullName variable to name given to its string parameter givenName while setAge method does the same with the ageYears variable in initializing it. This is also done by the ID method. These variables are then used by printAll method in printing out the Name and age of the object which would be created with the petData class

E. g: petData dog= new petData();

The human brain can store both temporary and permanent bits of information. Which type of memory in the computer is similar to t
aleksklad [387]

Answer:

RAM

Explanation:

"RAM" refers to <em>Random-Access Memory. </em>Just like the human brain, this stores your computer files temporarily. It is considered to be a <em>"volatile memory"</em> which means that information can only be stored<u> when there's power.</u> So, when your computer shuts down,<u> the information is los</u>t. This is similar to the human brain, especially when it comes to learning. When a person learns new things, some of the information he read before may be forgotten.

Assuming that a user enters 5 as the age, what is the output of the following code snippet? int age = 0; Scanner in = new Scanne

It will print out this way because the code uses if statements, rather than else if statements. As written, every single if statement will be triggered because each expression will evaluate to true. If there were else statements involved, then only the first one that is triggered will print out, and the rest will be ignored.

The reason for the weird formatting/spacing is because only the first print statement is println which adds a new line after printing. The other statements are just print, which does not add a new line or a space.
