Bonjour Service

What is Bonjour Service (comes during Installation of Photoshop CS3)?Firewall asks whether to allow or block this service to connect internet. which is safe...to allow or to block ?

I'll have a little more insight tonight, but here's my thought right now:
Could it be Apple's (open-source) zero-conf networking protocol?
