There are different formats for different devices (including devices other than cameras), and the SD card manufacturer will just give you an unformatted one or say on the packaging how its formatted.
You're also going to want to get your pictures off the SD card. You can keep buying SD cards, or copy them to a PC (which I do). Your PC may have a slot for SD cards. If not, you'll need an adapter.
