g What advantage does a circuit-switched network have over a packet-switched network? What advantages does TDM have over FDM in

REY [17]

Answer:

Advantages of a circuit-switched network over a packet-switched network are:

In Circuit-switched networks, resources needed to provide communication between the end systems for the duration of the session are usually reserved unlike in packet-switched networks where they are not reserved.
Circuit-switched networks have faster communication, so they can be used for Voice/Video calls
Circuit-switched networks have less errors in communication
Circuit-switched networks are more suitable for real-time services. Packet-switched networks are simpler, more efficient, and less costly to implement. They also offer better sharing of transmission capacity than circuit-switched network

Advantages does TDM have over FDM in a circuit-switched network are;

In TDM, all connections operate at the same frequency , but In FDM, all connections operate at different frequencies
In TDM there is low interference between the signals that are being multiplexed as compared to FDM.
In TDM, bandwidth is saved by allocating time slots on demand dynamically
TDM systems are more flexible than FDM

Write a method so that the main() code below can be replaced by simpler code that calls method calcMilesTraveled(). Original mai

patriot [66]

Answer:

See explanation

Explanation:

From the question, you have answered the question. However, it is poorly formatted.

So, I'll help present the code properly and also give explanation using comments.

import java.util.Scanner;

public class CalcMiles{

//This line defines the calcMilesTraveled method

private static double calcMilesTraveled(double milesPerhour, double minsTraveled){

//This declares hoursTraveled

double hoursTraveled;

//This declares milesTraveled

double milesTraveled;

//This calculates the hoursTraveled

hoursTraveled = minsTraveled/60.0;

//This calculates the milesTraveled

milesTraveled = hoursTraveled * milesPerhour;

//This returns the milesTraveled

return milesTraveled;

}

//The main method begins here

public static void main(String [] args){

//This declares and initializes milesPerhour

double milesPerhour =70.0;

//This declares and initializes minutesTraveled

double minutesTraveled = 100.0;

//This calls the calcMilesTraveled function and also prints the required result

System.out.println("Miles: "+calcMilesTraveled(milesPerhour, minutesTraveled));

}

klasskru [66]

Answer:

authentication

Explanation:

At the authentication process, there is a way of identifying a user, this is typically done by having the user enter a valid user name and valid password before access is granted. Here at authentication the process is based on each user having a unique set of criteria for gaining access.

The AAA server have to ascertain by comparing a user's authentication credentials with other user credentials stored in a database. In the event the credentials match, the user is granted access to the network. But on the other hand, If the credentials varies, and authentication fails then network access will be denied.
