The yellow curve is more valuable for non-economists. On a graph, this curve represents the maximum you would pay per quantity of allocated bandwidth The amount of data transmitted or received per unit of time. When we refer to acquiring or selling bandwidth, we mean the amount of information that can be sent over a connection at one time, at the allowed speed, without packet loss or excessive delay. Bandwidth is measured in bits-per-second.. The amount you actually pay depends on the bid of the second-highest bidder..
