Päätepiste

Päätepiste is a Finnish term that translates to endpoint or terminus in English. It refers to a point that marks the end of something: a path, process, route, or boundary. The term is used across disciplines to denote a final or terminating point.

In geometry, an endpoint is one of the two points that determine a line segment or the starting point of a ray. Endpoints are discrete points with defined positions, often described by coordinates.

In information technology and networking, a päätepiste or endpoint is a device or process that marks the termination of a communication channel or the entry point of a service. Examples include client devices, servers, APIs, and end-user applications. In API design, an endpoint is a specific URL or URI where a service can be accessed.

In transportation and geography, a terminus or end station refers to the final stop on a transit line, such as a bus or train route. The term can also describe the farthest point in a route or the outer boundary of an area.

Etymology and usage: Päätepiste combines “pää” (end) and “piste” (point). In Finnish technical language, the word is used similarly to the English “endpoint” or “terminus,” though other terms like loppupiste may appear in some contexts. The concept is widely used in mathematics, computer science, and transport planning.
