To define constructors and member functions outside of a class's original scope, the operator can be used.

Answers

Answer 1
Answer:

Answer: Scope resolution operator(::)

Explanation: A member function and the constructor can be called within the function easily but for the execution of the these components outside the class , a special operator is required to call the functions. The scope resolution operator(::) preceding with the name of class is thus used for defining of the function outside class.This operator maintains the cope of the function and constructor outside the class.

To return the value of the cell D8, the formula should be OFFSETA1=________.

Answers

Answer:

The formula is =OFFSET( A1, 7,3,1,1 )

Explanation:

Microsoft excel is a statistical and analytical tool for data management and analysis. Its working environment is called a worksheet. The worksheets are made up of rows and columns also known as records and fields respectively.

Functions like OFFSET in excel is used to return a cell or group of cells. It gets the position to turn by start getting a starting port, then the number of records below it and the fields after, then the length and width of cells to return.

syntax:   =OFFSET( "starting cell", "number of rows below", "number of columns after", "height of cells to return", "width of cells to return" )

In setting up to do RSA public key encryption, let p = 3 and q = 23 be the two initial prime numbers. Also let e = 5 be a randomly chosen value less than and relatively prime to Φ(n).Given the values above, compute the following. You must show all work to receive full credit:

What is the value of n ?
What is Φ(n) ?
Show that the value d = 9 is the modulo Φ(n) inverse of e.
What is the corresponding public key for these values?
What is the corresponding private key for these values?

Answers

Answer:

1. 69

2. 44

3. See explanation

4. (69,5)

5. (69,9)

Explanation:

1. n=p*q=23*3=69

2. Φ(n)=(p-1)(q-1)=2(22)=44

3. e=5,

    ed mod Φ(n)=9*5 mod 44=45 mod 44=1

4. Public key=(n,e)=(69,5)

5. Private key=(n,d)=(69,9)

In this exercise, we have to use the encryption knowledge to calculate what is needed, so we have:

1. 69

2. 44

3. 1

4. (69,5)

5. (69,9)

What is public key encryption?

Public key encryption, or public key cryptography, is a method of encrypting data with two different keys and making one of the keys, the public key, available for anyone to use. The other key is known as the private key.

1.So to perform the calculations of N, we have:

n=p*q=23*3=69

2.  For relatively prime calculations we have:

\phi (n)=(p-1)(q-1)=2(22)=44

3. So for the inverse module, we have:

 ed mod Φ(n)=9*5 mod 44=45 mod 44=1

4. For the public key, we have:

Public key=(n,e)=(69,5)

5. For the private key, we have:

Private key=(n,d)=(69,9)

You are experiencing issues when trying to transfer files between two computers using FTP. What could be the potential cause(s) of the issue

Answers

A potential cause of this issue with FTP is that the server is not able to resolve the client IP address.

What is FTP?

FTP is an acronym for file transfer protocol and it can be defined as a type of server that is designed and developed to store and provide files for download and sharing between two or more users on a computer system.

In this scenario, the user is most likely experiencing issues when trying to transfer files through the file transfer protocol (FTP) because the server is not able to resolve the client IP address, which is the address of the recipient of the file.

Debugging is not testing, but always occurs as a consequence of testing. A) TRUE
B) FALSE

Answers

It is true to say that Debugging is not testing but always occurs as a consequence of testing.

What is Debugging?

Debugging is the process of identifying and fixing defects in computer programs, software, or systems. It is a crucial step in computer programming and software development.

Debugging is used to identify and correct errors. The testing procedure just displays the consequences of the coding fault on the application; it does not assist the developer in identifying the mistake in the code.

Software developers and engineers use debugging to find and correct bugs in programs before making them available to the general public. It's an additional step to testing, which entails discovering how an issue impacts a program as a whole.

Debugging is the act of locating and fixing problems in software code that might lead to unexpected behavior or crashes. These mistakes are sometimes referred to as "bugs." Debugging is used to identify and fix faults or flaws in software or systems so that they don't operate incorrectly.

Which toplogy is common in these days? and justify atleast fivereason

Answers

Answer: Star topology is commonly used these days.

Explanation:

  • As, start topology is the reliable network topology because the failure of a central node or a node cable does not affect the remaining other nodes.
  • In star topology, if the computer fails you can still access your data by using backup folder in your private file or folder.  
  • In this network topology it is easy to find faults and correct it timely.
  • The start topology is cost effective and easy to maintain.  
  • We can also connect multiple communication channels.
