顯示ARP緩存信息.A R P高效運行的關(guān)鍵是由于每個主機(jī)上都有一個A R P高速緩存。這個高速緩存存放了最 近I n t e r n e t地址到硬件地址之間的映射記錄。高速緩存中每一項的生存時間一般為2 0分鐘,起 始時間從被創(chuàng)建時開始算起。

A Convex Hull is the smallest convex polygon that contains every point of the set S. A polygon P is convex if and only if, for any two points A and B inside the polygon, the line segment AB is inside P. One way to visualize a convex hull is to put a "rubber band" around all the points, and let it wrap as tight as it can. The resultant polygon is a convex hull.
