single player mode on minecraft
if you mean SSP then yes
You must buy another one or use Minecraft SP
Mineraft Sp is a hacked version of Minecraft so it's offline. I suggest you buy Minecraft if you want MultiPlayer.
no
Yes.
Not as of version 1.5.2
Nope and yes.It is like a demo for the full version of minecraft.

Yes you can. You can use it for Single Player AND Multiplayer. It works fine with LAN connections too.
Minecraft Premium refers to the status of your account (e.g. Free, Premium) while Minecraft SP is an acronym for Minecraft Single Player and refers to Single Player on the current version of the game (not classic). You require a premium account to be able to play Single Player on the current version.
No. You can play Minecraft singleplayer on any type of computer that's able it run it.
