RPCTarget basic concept

Options
Hello,
So I was really confused about this really basic concept.

when I use a photonView.RPC("Fire" , RPCTarget.All )

Am I calling the "Fire" function
1) on my client (on this PC) and my client instance on every other pc
or
2) on my client (on this PC) and my client instance on every other PC + everybody else's instance(player)
