Order

1. In computing, the relative significance of a digit or byte. High-order refers to the most significant (usually leftmost) digit or byte; low-order refers to the least significant (usually rightmost) digit or byte. 2. The magnitude of a database in terms of the number of fields it contains. 3. The sequence in which arithmetic operations are performed.

Orbit

The path of a body acted upon by the force of gravity. Under the influence of a single attracting body, all orbital paths trace out simple conic sections. Although all ballistic or free-fall trajectories follow an orbital path, the word orbit is more usually associated with the continuous path of a body which does not impact with its primary. The path described by a heavenly body in its periodic revolution. Earth satellite orbits with inclinations near 0 degree are called equatorial orbits because the satellite stays nearly over the equator.
