ISP Information:
Part of a system that limits the performance of the system. This term was derived from the neck of a bottle, which limits the flow of liquid due to the smaller circumference of the neck as compared to the wider body of the bottle. Often you will hear of people attempting to find and eliminate the bottlenecks in their computer systems or networks. This is certainly a helpful practice if the bottleneck is slowing things do

You may know this already--but the highway patrolman told her that you should NEVER drive in the rain with your cruise control on. He said if you did and hydroplaned (which she did) that when your tires were off the road your car would accelerate to a high rate of speed (which it did). You don't have much, if any control when you hydroplane, but you are totally in the hands of God when the car accelerates. She took off http://urbanlegends.about.com/library/bl-cruisecontrol-m2.htm"I'm sure real experts will chime in, but this sounds like hokum.Cruise control will try to regulate the speed based on the feedback froma tachometer downstream of the transmission (not the tach that showsengine speed). If a tire is spinning on the wet surface, the tire is nolonger providing traction, hence it is no longer affecting the speed ofthe car. When the tire starts to spin on the water, without the frictionof the road, it will be suddenly be going faster than the car and thecruise control will REDUCE the speed command.Once the tire regains grip, the speed feedback will be again match thespeed of the car. At this point, the car will be going slower than thespeed setpoint and the cruise control will increase the speed commanduntil the car is back to the setpoint. So, as the car hits the pavementagain, the car will automatically speed up, but only to the speed thatyou set your cruise control to regulate, no faster. It may surprise youbecause it goes from slowing down as you slide to accelerating(temporarily) as soon as you hit the pavement. " .... Douglas M.
