[Star Wars]Why does C3P0 refer to R2D2 as his "counterpart"?

Is it standard for droids to have a partner droid?

Droids that work together on a regular basis can, over time, become so accustomed to each other that they are considered counterparts. They essentially both develop code that forms a kind of "shortcut" when they're interacting, letting them function together much faster than normal droids can. They can also use that code to develop complex encryption codes that are virtually impossible to break for anyone but their counterpart.
