OpenSSH is an implementation of the SSH specification. It was created by OpenBSD developers and currently maintained by OpenBSD developers and another team which ensure it builds for other systems. For definitive info on the topic, visit their project web page:

You might want to pick up the O'Reilly book "SSH: The Secure Shell, The Definitive guide".

There are some differences in the names of some of the configuration files. The book covers both versions for protocols 1 & 2.

SSH is a closed source commercial-only program, openSSH is an open source re-implemenation of it done originally by the openBSD programmers.
