# Working with Operators

Operators are calculators or functions that manipulate (deform) or generate data. They are connected to objects or properties via any number of input and output ports and may also use one or more parameters. Operators read data from their input port(s), taking any parameter values into account, perform the specified calculation and then write the result onto their output port(s) using the operator's Update() method.
