From the Latin word zone This is where the concept that concerns us now comes. However, it should be stressed that this, in turn, has its etymological origin in the Greek and more exactly in the term ζώνη whose meaning was that of a belt, girdle or girdle.
According to the dictionary of the Royal Spanish Academy (RAE) , 'zone' is a noun that is used to describe both a important surface extension that has a strip or band shape as well as to the portion of a land or surface that is delimited , the territorial extension whose limits depend on issues related to politics and administrations and one girdle or list .

A free zone On the other hand, it is understood as a geographical area that is reserved for industrialization for export purposes, in which customs legislation is applied differently or, directly, does not apply.
In the sports field, the term we are now addressing is also very important. And more specifically in basketball. Thus, in said sports discipline, for example, there is talk of what is known as three seconds in the zone. An expression is established that when you are attacking you can not be more than that time in the restricted area of the opponent.
In the same way we also talk about the scoring areas of the court. These, which are located at different distances from the basket, are what determine that the right shots of the players are worth 3, 2 or 1 point.
