Answer:

The answer is "2".

Explanation:

In the given question some information is missing, that is "The propagation time for satellite to earth" which is "270 milliseconds" so, the description to this question can be defined as follows:

Given values:

Bandwidth = 64 kbps

Data frames = 512 bytes  

Propagation Time (t​​​​​​p ) =270 ms

Change Bandwidth  kbps to bps:

1 kb= 1024 bytes

calculated bandwidth= 64 kbps = 64×1024 bps = 65536 bps

1 bytes = 8 bits

512 bytes = 512 × 8 =  4096 bits

Frame length = 4096 bits

Formula

Transmission time (T​​​​​​t) = Frame length /Bandwidth

Window size = 1+2a

where a = Propagation time/Transmission time

Calculate Transmission time:

Transmission time (T​​​​​​t) = 4096 / 65536

Transmission time (T​​​​​​t)= 625 m.sec

Calculate Window size:

Window size = 1+2(270/625)

Window size = 1+2(0.432)

Window size = 1+0.864

Window size = 1.864

Window size = 2

DerKrebs [107]

Answer:

A) False

Explanation:

Extranet

An extranet acts as a shared network, disseminating information present on the intranet. That is, if a private intranet shares some of its content with other users (be they sellers, customers, etc.), this shared network is what we call the extranet.

Intranet

Today, companies are looking for tools and methods to align internal communication, reduce costs, and centralize information and files. The intranet is one of these tools, which works restricted to a specific audience, such as a company. This way, collaborators can access it with their specific username and password.

The intranet is, then, a closed and internal network, and still allows the use of more communication protocols besides HTTP. Intranet access is typically done on a local server and a local network, which we call LAN, which means Local Area Network installed within the company.

This internal network connects users, allowing information exchange, file and document management, centralizing communication between users. With this tool, you can quickly and securely and efficiently connect companies and departments.

Write a public static method diagSum, which takes a 2d array of int values as a parameter, and returns the sum of the elements i
saveliy_v [14]

A 2d array (i.e. 2 dimensional array) represents its elements in rows and columns

<h3>The program in Java</h3>

The method in Java, where comments are used to explain each line is as follows

//This defines the method

public static int diagSum(int[][] myArray) {

    //This initializes sum to 0

    int sum = 0;

    //This iterates through each row of the array

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

                   //This calculates the sum of the diagonals

                       sum+=myArray[i][i];

               }

               //This returns the sum

               return sum;
