The given statement is False

Explanation:

OSI or Open System Interconnection is a reference model around which the networks are built. OSI gives us all the information regarding movement of data from a software through physical means to another software. Generally it is used as a guidance tool. Seven layers combine to build an OSI model/

TCP/IP (Transmission control protocol/ Internet protocol) model is in a way implementation of the OSI model. It tells about the end-to-end transmission of data being transmitted using OSI model.

Answer:

CIRCLE.JAVA

public class Circle {

private double radius;

public Circle(double myRadius) {

radius = myRadius;

private void setRadius(int myRadius){

radius = myRadius;

}

public double getDiameter() {

return radius*2;

}

public double getRadius() {

return radius;

}

public double getPerimeter() {

return Math.PI*getDiameter();

}

public String toString() {

return "Circle with a radius of " + radius;

}

CIRCLE TESTER.JAVA

public class CircleTester {

public static void main(String[] args) {

Circle circ = new Circle(10);

circ.radius = 5;

System.out.println(circ);

System.out.println("The diameter is " + circ.getDiameter());

System.out.println("The perimeter is " + circ.getPerimeter())

}

Explanation:

public class Circle {

//This could be made private or public.

//Making it private is better

private double radius;

//This is a constructor. It should be made public

//since it would most likely be used in another class

//to create an object of this class.

//Making it private means no other external class can create

//an object of this class.

//Since the tester class (CIRCLETESTER.java), as shown on line 3,

// needs to create

//an object of this class, this should be made public

public Circle(double myRadius) {

radius = myRadius;

private void setRadius(int myRadius){

radius = myRadius;

}

//This should be made public since it will be

// used in another class (CIRCLETESTER.java in this case)

public double getDiameter() {

return radius*2;

}

public double getRadius() {

return radius;

}

//This should be made public since it will be

//used in another class (CIRCLETESTER.java)

public double getPerimeter() {

return Math.PI*getDiameter();

}

//The toString() method is the string representation

//of an object and is called when there is an attempt to

//print the object. It should be made public since it will

//be used in another class (CIRCLETESTER.java)

public String toString() {

return "Circle with a radius of " + radius;

}

CIRCLE TESTER.JAVA

public class CircleTester {

public static void main(String[] args) {

Circle circ = new Circle(10);

circ.radius = 5;

System.out.println(circ);

System.out.println("The diameter is " + circ.getDiameter());

System.out.println("The perimeter is " + circ.getPerimeter())

To use it, the members must make sure there's only an individual collision as well as they broadcast IP address between both the router and the switch through which the congestion is received.

Windows stores information from the Credential Manager application in secure folders called VAULTS.

Explanation:

A credential vault is a database used to store passwords and similar cryptographic key material.
The most common data stored in a credential vault are current and historical passwords to privileged accounts.
All credentials are saved in special folders on the computer, a place called Vaults. Moreover, you can back up all credentials to a file and restore them on to different computer.
Vault is a shareware program that acts as a bank vault, or safe, where you can keep you private information or files hidden and secure.
Everything in the vault is protected with an advanced encryption, and requires a password (your password) to open the vault to access the information.
