Answer:
The main difference between LAN, MAN and WAN is the scope and coverage of the networks. LAN (Local area network) is usually used to connect computers in smaller distances such as in a building or in offices. They use various topologies such as bus topology, ring topology, star typology etc to connect the computers and share information only among the computers connected in LAN. A Metropolitan Network covers larger coverage than LAN and is usually used for connecting a city rather than single organization. A Wide Area Network is collection of networks or many LANS. The perfect example of WAN is internet which connects thousands and millions of networks. Another factor which distinguishes between LAN, MAN and WAN is that LAN and MAN are owned by certain entities such as government, educational institutions or organizations whereas WAN (i.e. Internet) is not owned by anyone.

Answer:
PING
Explanation:
To check if there's still connectivity between the computer and server, I would use the ping command.
The ping command is primarily a TCP/IP command. What this command does is to troubleshoot shoot. It troubleshoots connection and reachability. This command also does the work of testing the name of the computer and also its IP address.
I would say the best clear answer is D, because A is a little bit unclear but I would say the best answer is D.
Why?
Mesh Topology is expensive considering more links as compared to Ring topology.
Answer:
import java.util.*;
public class Main {
public static void main(String[] args)
{
Scanner scan = new Scanner();
double budget=0, num=0, total=0;
System.out.println("Your budget for the month? ");
budget=scan.nextDouble();
System.out.println("enter all expense, and after that type -9999 to quit: ");
while(num != -9999)
{
total+=num;
num=scan.nextDouble();
}
if(total<=budget)
{
System.out.println("under budget by ");
System.out.println(budget-total);
}
else
{
System.out.println("over budget by ");
System.out.println(total-budget);
}
}
}
Explanation:
- Take the budget as an input from user and store it to the budget variable.
- Loop until user has entered all his expenses and keep on adding them to the total variable.
- Check If the total is less than or equal to budget or otherwise, and then print the relevant message accordingly.
