Course

Course can refer to:

Course (sail)

In sailing, a course is the lowermost sail on a mast.

This term is used predominantly in the plural to describe the lowest sails on a square rigged vessel, i.e., a ship's courses would be the foresail, mainsail, and, on the rare occasions in which one is shipped, mizzen.Gaff-rigged vessels may use the term (for the lowest sail rigged aft of each mast), but are more likely to refer simply to a mainsail, foresail, etc. A Bermuda- or lateen-rigged yacht, whether sloop, cutter, ketch or yawl, would not usually be described as having a course.

Course (navigation)

In navigation, an object's course is the direction over the ground along which the object is currently moving.

Course, track, route and heading

The line connecting the object's consecutive positions on the ground is referred to as the ground track. The track the object was intended to follow is called the route. For ships and aircraft, the route is represented by the great circle line that connects the previous waypoint with the next waypoint. The responsibility of a navigator is to make the track coincide as much as possible with the route. The direction of the route is called the route course. "Course" exceptionally, and arguably erroneously, may also refer to the route, such as in a course deviation indicator, in which case it no longer constitutes an angle but rather a line. The direction of the great circle line that runs from the current position to the next waypoint is called the course to steer, or the bearing to that waypoint. The tracking angle is the angle between the course to steer and the course. The heading is the direction to which the "nose" of the object is pointing, its orientation.

Online and offline

The terms "online" and "offline" have specific meanings in regard to computer technology and telecommunications in which "online" indicates a state of connectivity, while "offline" indicates a disconnected state. Common vernacular extended from their computing and telecommunication meanings and refers specifically to an Internet connection. Lastly, in the area of human interaction and conversation, discussions taking place during a business meeting are "online", while issues that do not concern all participants of the meeting should be "taken offline" — continued outside of the meeting.

Definitions

In computer technology and telecommunication, online and offline are defined by Federal Standard 1037C. They are states or conditions of a "device or equipment" or of a "functional unit". To be considered online, one of the following may apply to a system: it is under the direct control of another device; it is under the direct control of the system with which it is associated; or it is available for immediate use on demand by the system without human intervention.

Online (disambiguation)

The term "online" can refer to a state of connectivity.

"Online" is a moderate up-tempo song whose lyrics satirize the online world, specifically MySpace. Here, the song's protagonist is a geek who lives at home with his parents, holds a job at the local Pizza Pitt pizzeria, and claims limited success in the dating world. Actually "five-foot-three and overweight", a fan of science fiction, and a mild asthmatic, the main character has an account on MySpace. There, he assumes a much more desirable personality: "Online, I'm out in Hollywood / I'm six-foot-five and I look damn good / I drive a Maserati / I'm a black-belt in karate / And I love a good glass of wine". Later in the song, he claims to live in Malibu, California, have a sexy, finely sculptured body, and pose for Calvin Klein Inc. and GQ. The fictitious alternate personalities make the geek claim that he is "so much cooler online". The album version of the song ends with a marching band playing the melody of the chorus, a reference to an earlier line where the protagonist claims to play tuba in a marching band.
