In telecommunications, a point-to-point connection refers to a communications connection between two communication endpoints or nodes. 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 ...
In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communication protocol between two routers directly without any host or any other networking in between. [1] It can provide loop detection, authentication, transmission encryption, [2] and data compression. PPP is used over many types of physical networks ...
Point-to-point transit. Point-to-point (top) vs hub-and-spoke (bottom) networks. Point-to-point transit is a transportation system in which a plane, bus, or train travels directly to a destination, rather than going through a central hub. This differs from the spoke-hub distribution paradigm in which the transportation goes to a central ...
Point-to-multipoint is the most popular approach for wireless communications that have a large number of nodes, end destinations or end users. Point to Multipoint generally assumes there is a central base station to which remote subscriber units or customer premises equipment (CPE) (a term that was originally used in the wired telephone ...
Point-to-point construction. Section of a typical Australian late 1930s radio, showing the point to point construction between components. In electronics, point-to-point construction is a non-automated technique for constructing circuits which was widely used before the use of printed circuit boards (PCBs) and automated assembly gradually ...
Ethernet. The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP 's IP network, and from there to the rest of the Internet.
v. t. e. The Point-to-Point Tunneling Protocol (PPTP) is an obsolete method for implementing virtual private networks. PPTP has many well known security issues. PPTP uses a TCP control channel and a Generic Routing Encapsulation tunnel to encapsulate PPP packets. Many modern VPNs use various forms of UDP for this same functionality.
Point-to-point (steeplechase) A point to point race. A point-to-point is a form of horse racing over fences for hunting horses and amateur riders. In Ireland, where the sport is open to licensed professional trainers, many of the horses will appear in these races before they compete in National Hunt races. Consequently, the Irish point-to-point ...
