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 ...
Point-to-Point Protocol. Point-to-Point Protocol. 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.
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.

The point-contact transistor was the first type of transistor to be successfully demonstrated. It was developed by research scientists John Bardeen and Walter Brattain at Bell Laboratories in December 1947. [1][2] They worked in a group led by physicist William Shockley. The group had been working together on experiments and theories of ...
Switched point-to-point topologies are the basic model of conventional telephony. The value of a permanent point-to-point network is unimpeded communications between the two endpoints. The value of an on-demand point-to-point connection is proportional to the number of potential pairs of subscribers and has been expressed as Metcalfe's Law.
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 location where passengers change to another train, bus, or plane to reach their destination.
Point of contact. A point of contact (POC) or single point of contact (SPOC) is a person or a department serving as the coordinator or focal point of information concerning an activity or program. A POC is used in many cases where information is time-sensitive and accuracy is important. For example, they are used in WHOIS databases. [1]
