The conventional wisdom concerning the security frameworks of domains is that it is always preferable for an organization to cre

Valentin [98]

Answer:

False

Explanation:

A Domain Based Security. "Domain Based Security", abbreviated to "DBSy", is a model-based approach that is being used in analyzing information security risks in a business context and offers an apparent, understandable and direct mapping among the risks and the security controls needed to handle them.

While A security domain is the list of items a subject is permitted to access. More largely defined, domains are collections of subjects and objects with related security requirements.

If a 9V, 7W radio is on from 9am to 12pm. Calculate the amount of charge that flows through it, hence or otherwise the total num

vredina [299]

Answer:

Q=It

and

p=IV

Given, v=9V P= 7W

I=P/V

I =7/9

Also, time(t) from 9am to 12pm is 3hrs

Converting into sec =3×3600

t=10800

Q= 7/9 ×10800

Q =8400C

"Switches break up _______________ domains and routers break up _____________ domains."

mel-nik [20]

Answer:

Switches break up collision domains and routers break up broadcast domains.

Explanation:

Collision domain depicts the part within a network where a collision can happen.
Collision occurs when two hosts transmit data packet at the same time within a network. Theses packets collide and the hosts have to resend the data after some time.
Too many collisions can result in slow traffic speed and can effect network performance.
So switches break up collision domains between the devices on a network and each port in a switch depicts a collision domain. This reduces the chance of packet collisions between the devices or hosts.
When data is to be sent to a host, the switch keeps that data frame and waits for availability of the destination host before sending the data frame.
Moreover full duplex switch mode there is not chance of collision as the transmitting path on one host is the receiving path on other host.

Broadcast domain contains all the hosts that can reach each other at the Data Link layer via broadcast.
Routers break up broadcast domains as routers contain separate broadcast domains for each interface.
Routers do not forward broadcasts from one broadcast domain to other and drop the packet when they detect a broadcast address.

There are 12 inches in a foot and 3 feet in a yard. Create a class named InchConversion. Its main() method accepts a value in in

Dafna1 [17]

Answer:

import java.util.Scanner;

public class InchConversion

{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("Enter inches: ");

double inches = input.nextDouble();

inchesToFeet(inches);

inchesToYards(inches);

}

public static void inchesToFeet(double inches){

double feet = inches / 12;

System.out.println(inches + " inches = " + feet + " feet");

}

public static void inchesToYards(double inches){

double yards = inches / 36;

System.out.println(inches + " inches = " + yards + " yards");

}

Explanation:

In the inchesToFeet() method that takes one parameter, inches:

Convert the inches to feet using the conversion rate, divide inches by 12

Print the feet

In the inchesToYards() method that takes one parameter, inches:

Convert the inches to yards using the conversion rate, divide inches by 36

Print the yards

In the main:

Ask the user to enter the inches

Call the inchesToFeet() and inchesToYards() methods passing the inches as parameter for each method
