devices - help me understand

[leegold]

Here's a question I've had for a long time
about devices: eg. For the same piece of hardware,
let's say a sound card there a three (3) identifiers:

pcm (this id is in the kernel file)
sbc0 (this id is in the dmesg output)
snd0 (this id is in the /dev directory)

Whaz up w/this? They all are for, or support the
same piece of hardware. What each one's purpose?

Thanks
