An object is in a vertical position when it is aligned in an "up-down" direction, roughly speaking perpendicular to the horizon or horizontal. Even though the similar to the term "vertex" suggests that it has the same position value; but both ends are opposite.
A pair of angles are said to be vertical if they share the same vertex and are bounded by the same pair of lines but are opposite to each other.
In networking the vertical is typically the portion of network cabling that runs between floors, and is usually considered the backbone.
