Read the Mathematica tutorial on Contexts. Here's one paragraph therefrom: The basic idea is that the full name of any symbol is broken into two parts: a context and a short name. The full name is written as context`short, where the ` is the backquote or grave accent character (ASCII decimal code 96), called a "context mark" in Mathematica.
