Read their respective Wikipedia pages:

RPC - https://en.wikipedia.org/wiki/Remote_procedure_call

LPC - https://en.wikipedia.org/wiki/Local_Procedure_Call

Everything is explained there. First put some effort into it and if you get stuck you can still pose a non-trivial questions.

Differences:

  • RPC is slower than LPC since it uses the network to invoke the method.
  • With RPC the procedure call can be executed on a remote machine which can be addressed in several ways.
  • The parameters and return value need to be serializable (to use java terminology).
  • RPC's can fail due to network issues.
  • RPC's need to be set up before using them.
  • The language used to call the remote procedure and the language implementing the remote procedure are not necessarily the same.
  • and more.

In RPC, programs can be executed from a different computer while in LPC, programs are executed by the host computer.
