In telecommunications, a point-to-point connection refers to a communications connection between two nodes or endpoints. An example is a telephone call, in which one telephone is connected with one other, and what is said by one caller can only be heard by the other. This is contrasted with a point-to-multipoint or broadcast communication topology, in which many nodes can receive information transmitted by one node. Other examples of point-to-point communications links are leased lines, microwave relay links, and two way radio. Examples of point-to-multipoint communications systems are radio and television broadcasting.
The term is also used in computer networking and computer architecture to refer to a wire or other connection that links only two computers or circuits, as opposed to other network topologies such as buses or crossbar switches which can connect many communications devices.
Point-to-point is sometimes abbreviated as P2P. This usage of P2P is distinct from P2P referring to peer-to-peer file sharing networks.
A point-to-point is a form of horseracing over fences for hunting horses and amateur riders. In Ireland, where the sport is open to licensed - i.e. professional - trainers, many of the horses will appear in these races before they compete in National Hunt races. Consequently, the Irish point-to-point is more used as a nursery for future young stars: a horse that wins its debut point-to-point in Ireland will often sell for a lot of money. Whilst professional trainers are specifically excluded from running horses in point-to-points in Great Britain (other than those which are their own personal property), the days of the farmer running his hunter at the local point-to-point have gone. Increasingly, horses are run from "livery yards" - unlicensed but otherwise professional training establishments, sometimes closely allied with a licensed yard.
Horses running in Point-to-Points must be Thoroughbreds, save in the case of Hunt Members races and certain other Club Members races (e.g. Pegasus Club Members race). The owner must be a member, subscriber or farmer of a recognized pack of Hounds and obtain a Hunter Certificate from the Master to that that effect. Once this Certificate has been registered with the Point-to-Point Authority (PPA) the horse is also eligible to run in Hunter Chases, i.e. races for similarly qualified horses run under BHA Rules over regulation fences on licensed racecourses. Similarly, potential riders must also obtain a Riders Qualification Certificate (RQC) from a Hunt Secretary and register it with the PPA.
Point-to-Point racing is also sometimes referred to as racing 'between the flags'.

The first race I ever rode in was the Isle of Wight Foxhounds point-to-point over on the mainland, and I fell off.
What looked like glowing green strings were, he knew, laser beams in the infrared frequency: point-to-point sensors with columnated beams of light, invisible to the naked eye.
We're shutting off the whole of this end of the stands, of course, and are having to move everyone and everything along into Tattersalls, but so far I've only managed a promise of a couple of Portakabins for the changing rooms and it looks as if we're going to have to have the scales out in the open air, as they used to do at point-to-points.
They ripped wormhole endpoints free of the routers and turned them into their own crude point-to-point network, learned how to generate new wormholes, then ran their own packet-switched polities over them.
They certainly are not steeplechases, we are critically short of steeples out here, and they are not point-to-point exactly, for we throw in a little rifle drill.
It requires either a point-to-point (PPP) or SLIPconnection, which allows you to run pretty pictures with your Web browser.
