top,

toy with a tapering point on which it can be made to spin. Tops were known in antiquity and appeared in Europe during the Middle Ages; they are used today in many different regions of the world by both primitive and advanced societies. The principle of its motion is utilized in the gyroscopegyroscope
, symmetrical mass, usually a wheel, mounted so that it can spin about an axis in any direction. When spinning, the gyroscope has special properties. Many spinning objects exhibit some of these properties; the rotation of the earth about its axis gives it the

A rigid body, one point of which is held fixed in an inertial reference frame, and which usually has an axis of symmetry passing through this point; its motion is usually studied when it is spinning rapidly about the axis of symmetry.

(Technical Office Protocol) A communications protocol for office systems developed in the early 1980s by the Computer Services division of Boeing in Seattle, WA. It is often used in conjunction with MAP, the factory automation protocol developed by GM. TOP is used in the front office, and MAP is used on the factory floor. TOP uses the CSMA/CD access method (Ethernet), while MAP uses token bus.
