a position in space, representing things such as gas stations, post boxes, shops and the like. Often called a waypoint.

a list of points (often with names) connected in a specific order. Usually a collection of waypoints defining the route you want to pass while traveling, created by PC software, or generated inside a GPS device. They can be composed of existing waypoints, or new "routepoints" might be generated.

a collection of locations recorded by your GPS device while traveling -- "breadcrumb trails". The order of trackpoints within the track is important. Usually a trackpoint doesn't have a name or comment, but usually has a timestamp. This distinguishes a trackpoint from a waypoint.

are geopoints that are not necessarily connected to other points, and their order is unimportant. They can be entered before, while or after you actually visit the place and might have tags like name, comment and the like. Usually used to mark special locations as your home, a hotel or a geocache.
