`/0` refers to the arity of the function.

It's the arity of the function. In Erlang there are no variadic functions, but functions with different arities can have the same name, so universal_server/0 takes no arguments, fib/1 takes 1 argument, fib/2 takes 2 arguments, the second arg may be the accumulator for a recursive Fibonacci, for example, and fib/1 may call fib/2 as an implementation detail.
