Point-to-point is abbreviated as P2P occasionally. In the context of file sharing networks or other data sharing protocols between peers, this use of P2P is distinct from P2P, meaning peer-to-peer.
Basic connection to data

A conventional point-to-point data link is a means of communication with exactly two endpoints and no formatting of data or packets. For the formatting of the data transmitted between them, the host computers at either end take full responsibility. In general, via an RS-232 or similar interface, the link between the device and the communication medium was implemented. Computers in close proximity can be directly connected between their interface cards by wires.indiana convention center

Each endpoint will be equipped with a modem to convert analog telecommunications signals into a digital data stream when linked at a distance. The connection is called a dedicated, leased, or private line if the connection uses a telecommunications provider. To provide point-to-point data links between its packet-switching nodes, which were called Interface Message Processors, the ARPANET used leased cables.

The word point-to-point telecommunications in modern computer networking implies a wireless data link between two fixed points. Usually, the telecommunications signal is bi-directional and either time division multiple access (TDMA) or channelized. This can be a microwave relay link consisting of a transmitter that transmits a narrow beam of microwaves to a second parabolic dish at the receiver with a parabolic dish antenna. Technologies such as lasers that relay data modulated by a light beam are included. These technologies involve an unobstructed line of sight between the two points and are restricted to distances of around 40 miles by the visual horizon (64 km).
