All right, cool. Thanks for your help.

Also, I am stumped with these 2.. Can you please help?

1) What are the key elements that must be considered when designing a LAN?

2) What are the different routing techniques that are used in WANs?

Please review the guidelines on asking for help with homework that can be found here:

Second, I moved this from your other thread since your quiestions are not related to programming.
