Not "were" - are! :-) You missed OpenBSD, the 3rd "big BSD" around today. There are also operating systems derived from those BSDs, such as DragonflyBSD or HardenedBSD (both from FreeBSD). > What points did they focus by design? Even though they are multi-purpose operating systems, their focus is a little different. You can find out from the primary sources of the projects: 1. The FreeBSD Project The Power To Serve FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The NetBSD Project "Of course it runs NetBSD" NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices. Source: https://www.netbsd.org/ Further reading: https://www.netbsd.org/about/ 3. OpenBSD Only two remote holes in the default install, in a heck of a long time! The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography. As an example of the effect OpenBSD has, the popular OpenSSH software comes from OpenBSD.

Oversimplified: NetBSD is the candidate for "runs everywhere", so it's very useful for embedded systems and "strange" hardware platforms; OpenBSD has security as primary goal, that makes it perfect for servers; FreeBSD is also used for embedded, servers, and desktops. In an attempt to summarize, all the BSDs can be used for almost everything - from embedded, to laptops, desktops, servers, and "combined forms". In reality, you _will_ find BSDs in all those places, and you will also find them in places where you don't know there is a BSD running, for example in routers, managed switches, NAS, WLAN APs, firewall and other networking appliances. They are also used as development platforms for a lot of other systems. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
