what is exactly difference between iptables and netfilter?

Is it correct that iptables uses from netfilter for doing it's work and iptables is only a interface for netfilter?

iptables is userspace, netfilter is kernelspace.

Quote:

"The actual Netfilter implementation is broken into two parts, the kernel portion known as Netfilter and the userland tool that interfaces with Netfilter and creates the rulesets, iptables. Both are required to implement your packet-filtering firewall."

borrowed from http://www.linuxjournal.com/article/4815 - fifth paragraph.

And here is a lot of good documentation.
