When this collision condition is detected, the station stops transmitting that frame, transmits a jam signal, and then waits for a random time interval before trying to resend the frame. [1] CSMA/CD is a modification of pure carrier-sense multiple access (CSMA).

From the planetary frame of reference, the ship's speed will appear to be limited by the speed of light — it can approach the speed of light, but never reach it. If a ship is using 1 g constant acceleration, it will appear to get near the speed of light in about a year, and have traveled about half a light year in distance. For the middle of ...
In computer networking, cut-through switching, also called cut-through forwarding [1] is a method for packet switching systems, wherein the switch starts forwarding a frame (or packet) before the whole frame has been received, normally as soon as the destination address and outgoing interface is determined.

A counterweight is a weight that, by applying an opposite force, provides balance and stability of a mechanical system. [1] The purpose of a counterweight is to make lifting the load faster and more efficient, which saves energy and causes less wear and tear on the lifting machine. [2]
Relative velocities between two particles in classical mechanics. The figure shows two objects A and B moving at constant velocity. The equations of motion are: where the subscript i refers to the initial displacement (at time t equal to zero). The difference between the two displacement vectors, , represents the location of B as seen from A.
