Networking components will eventually interact with computers and devices outside of itself. Whereas during system development you are only interacting with your program internally.
For example, when you first work on a website you can begin working on it on your personal computer not connected to the outside world. When you are done working on your website you will now upload it to a webserver (or you will create your webserver) and now you are opening up the doors so to speak to the Internet. When you "open the door" you need to make sure the proper security is in place so that no one hacks your site. This is ussually done by making sure the webserver you are on does not have any known security vulnerbilities and has the proper firewall settings to prevent unauthorized access.
Answer:
As a high-quality communication system, online games provide a virtual world where gamers communicate with each other by using rich interactive multimedia. This would facilitate communication among online gamers and enhance the development and maintenance of interpersonal relationships.
A LAN (local area network) is a group of computers and network devices connected together, usually within the same building. By definition, the connections must be high speed and relatively inexpensive (e.g., token ringor Ethernet). Most Indiana University Bloomington departments are on LANs.
A LAN connection is a high-speed connection to a LAN. On the IUB campus, most connections are either Ethernet (10 Mbps) or Fast Ethernet (100 Mbps), and a few locations have Gigabit Ethernet (1000 Mbps) connections.
A MAN (metropolitan area network) is a larger network that usually spans several buildings in the same city or town. The IUB network is an example of a MAN.
A WAN (wide area network), in comparison to a MAN, is not restricted to a geographical location, although it might be confined within the bounds of a state or country. A WAN connects several LANs, and may be limited to an enterprise (a corporation or an organization) or accessible to the public. The technology is high speed and relatively expensive. The Internet is an example of a worldwide public WAN.
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.
