AS per my understanding -

A Primary actor is  one who uses the system to achieve a goal. This could be an end user or an admin or anyone for whom the system was developed.
Secondary actor is one who assists the primary actor in achieving said goal. This can be a person, or a bank, or a printer.

The main difference between a Primary and Secondary actor is

Primary Actors: The Actor using the system to achieve a goal. The Use Case documents the interactions between the system and the actors to achieve the goal of the primary actor.

Secondary Actors: Actors that the system needs assistance from to achieve the primary actor's goal.

Actors are that the system you are describing interacts with .Actors is a living or non living thing .
Actor is represented by a noun .Actors are always stay away from system boundary.There are 2 types of actor Primary and Secondary actor.

Primary actor -who initiates the system to work and system depends on secondary actor for information .

Usually Primary actors are placed on left side and secondary actors are placed on right side of system boundary .

Actors are majorly two:
1)Primary Actor
2)Secondary Actor

1)Primary Actor are those who are directly interacting with the use case.
2)Secondary Actor are those who indirectly interacts with the use case.

Use case actors
   An actor is a noun living or non living thing

   Every use case will have actors and has specific goals primary actor initiates provide input to it and receive output to it , processing the information or system depends on the information is a secondary actor Ė third party system

   Actors can be people, other system, time triggers
   Example: Stock maintenance system
   Does this have any external customer interacts or initiates the action? No

Itís just maintaining the stock details in a store admin does this so admin is consider as a primary actor

Does this rely on third party information to complete the admin goals as storing data? No stock details will be stored in database so here no secondary actor
