Most if not all of BSDs are distributed under variations of the Berkley license. I'm not sure if every single one has qualified with the Open Source Initiative : http://www.opensource.org/licenses/alphabetical
OSI is probably the most agreed upon (not actually agreed upon, just the most) authority on what is open source and what isn't.
Conclusion: OpenBSD is in an open source system. It is not a GPL style open source system in that is generally more permissive of copying, barring distributions prior to 1999 that had clauses affecting advertising that were later removed.
This varies widely from one OS to another. As with many other things it is commonly whatever the market will bear, as in general a computer without an operating system won't do much useful work. However there are opensource OSs (e.g. Linux, OpenVMS) that can be obtained free or at very low cost.

Yes. Apple has released Boot Camp, a program that allows one to easily install Windows XP or Vista on an Intel Mac. Various Linux distros, FreeBSD, NetBSD, and OpenBSD also run on Macs.
There are basically four types of operating systems. They include Batch Operating System, Multiprogramming Operating System, Network Operating System and Distributed Operating System.
1. BATCH PROCESSING operating system 2. MULTIPROGRAMMING operating system 3. TIME SHARING operating system 4. REAL TIME operating system 5. DISTRIBUTED operating system
OpenBSD is a free an open-source Unix-like operating system, with a primary focus on security.
OpenBSD has many services it offers from help with servers and securing them to streaming videos. OpenBSD is also a UNIX like operating system that was developed by them.
Open-source is a development model. Windows is an operating system.
Proprietary operating systems are commercial operating systems designed to run on specific computer hardware for which they are licensed. Other operating systems such as Linux and OpenBSD are free and open source and can be used on any hardware on which someone can make it work. The Android operating system is a Google implementation of Linux designed to work on smart phones and tablets.
Linux, FreeBSD, NetBSD, OpenBSD, and Darwin can run a limited number of Windows programs using Wine.
