Easiest way to fill the space between two holes?

[MedsoN]

Hey!
Sry for the noob question but i dont know how to connect two holes in the fastest way.

Until now i selected the verticles one by one, created a line between them, and then a face. Its realy time consuming and i think theres an easier / faster way to do this.
