Modes have been overly mystified. Technically a "modal" melody begins and ends on the same note. A mode is defined as the set of notes within the major scale beginning and ending on a specified degree. The names themselves are derived from islands off Greece. The origins of these names are obscure, and often attributed to the Greek Philosopher, Pythagoras.
They were associated with large group activities. For example the Dorian mode was associated with war. However, whether the modes as we define them, are the same as the ones we get fragmentary allusions to in Greek Literature is debatable.
For guitarists, the bottom line is that they are applied very loosely. Most of the time we use them as a way to memorize the positions of all the notes in the major scale in all positions. They are patterns from which we derive improvisations and classify the work of others. They are a convenient tool.
Major mode is the major scale. In C major it is C to C. For guitarists this is usually expressed in two octaves, because it is convenient for the instrument's structure to represent it that way. Theoretically it could be any number of octaves, but two keeps it expressed in one position on the instrument.
The other modes in C major follow suit. Dorian is built on the second scale degree which would be D. The pattern would start on the tenth fret. Similarly Phrygian starts on E, Lydian on F, Mixolydian on G, Aeolian, the relative minor, on A, and finally the Locrian starts on the seventh scale degree, B.
Since all patterns are moveable, we can apply them to any key we desire by imposing the templates on the appropriate position on the instrument.
