How have WLANs changed ‘hard edges' into ‘blurred edges'?
What will be an ideal response?
The introduction of wireless LANs in enterprises has changed hard edges to blurred edges. Instead of a network hard edge with a single data entry point and solid walls to protect physical access to the wired LAN, a WLAN can contain multiple entry points. In
addition, because RF signals extend beyond the boundaries of the building the walls cannot
be considered as a physical hard edge to keep away attackers.

(Simulation: The Tortoise and the Hare) In this problem you will recreate one of the truly great moments in history, namely, the classic race of the tortoise and the hare. You will use random number generation to develop a simulation of this memorable event.
Our contenders begin the race at “square 1” of 70 squares. Each square represents a possible position along the race course.
The finish line is at square 70. The first contender to reach or pass square 70 is rewarded with a pail of fresh carrots and lettuce.
The course weaves its way up the side of a slippery mountain, so occasionally the contenders lose ground.
There is a clock that ticks once per second. With each tick of the clock, your script should adjust the position of the animals
according to the following rules:
Use variables to keep track of the positions of the animals (i.e., position numbers are 1–70). Start each animal at position 1
(i.e., the “starting gate”). If an animal slips left before square 1, move the animal back to square 1.
Generate the percentages in the preceding table by producing a random integer, i, in the range 1 £ i £ 10. For the tortoise, per-
form a “fast plod” when 1 £ i £ 5, a “slip” when 6 £ i £ 7 or a “
