1) What are the modes of operation of WLANs?
2)How can an intruder jeopardize your network in WEP? What is the cardinale rule?
3)Java's built-in TreeSet class uses time in O(log n) for insertion and deletion. It seems that we could build a O(n log n) sorting algorithm by simply inserting all of the data into a TreeSet, then traversing the TreeSet inorder. The running-time analysis is correct, but this algorithm fails to sort some ArrayLists. Why? (Hint: Think about the definition of a set.)
