Actors: They represent the end users who are performing an action on the system. Basically, they play a major role in using functionality of the system.
These are again classified into 2 types:
Primary Actors ? They are the ones who is using the system on behalf of the user or may be just who directly interacts with the system. 
Secondary Actors ? They are the ones who support the system flow to execute the functionalities.

Primary Actor - Primary actors are mainly the stake holders through the process happens.

Secondary Actor - Secondary actors are the supporting factors which help the system to fulfill the action .

Eg :   Receptionist is receiving payment through Card uses swipe machine
 
          Here Receptionist is primary Actor and Swipe Machine will be the Secondary actor .

A primary actor :-
                               acts on the system
                               initiates an interaction with the system
                               uses the system to fulfill his/her goal

A secondary actor :-
                             is acted on/invoked/used by the system
                             helps the system to fulfills its goal

An Actor is the one who initiates an action with the system. Actors could be anybody from persons who are the users of the system to organization and system too. They are basically initiators of the system.
Primary Actor who initiates the process or action, rest all are secondary actors.
