Brake lights are twinkling and horns are honking as automobiles trickle bumper-to-bumper down the road. If you've ever commuted to work in a heavily populated area or driven to the beach on a holiday weekend, you're familiar. But bear with me. How many lanes does this imaginary highway have? For this example, let's say there are four. These four lanes are the *bandwidth*. And the cars are—you guessed it—the *traffic*. If you added two additional lanes (more bandwidth), what would happen? The highway could allow more cars to travel at the same time. And if you reduced the number of lanes down to just two? You'd get a traffic jam, a minivan full of fussy children, and a very frustrated parent threatening to turn the car around and scrap this year's beach trip. You need sufficient bandwidth to ensure you arrive on time. > Bandwidth determines how much traffic can pass through. In short, bandwidth determines how much traffic can pass through. More bandwidth can accommodate more traffic.
