了解NetBSD

　　An introduction to BSD

　　Three major BSD-derived operating systems are freely available: NetBSD, FreeBSD, and OpenBSD. All three systems are related to the original BSD distribution of UNIX, which dates back to the 1970s. In the early 1990s, at about the same time Linux® was coming together as a legitimate competitor to UNIX, a separate track was being forged to create a free UNIX-like operating system based on BSD. All three BSD versions have strong points, with FreeBSD leading the way in user base, OpenBSD leading in security, and NetBSD leading in portability.

　　Of course it runs on NetBSD

　　You can port NetBSD to run on just about anything with a processor -- hence the motto, "Of course it runs on NetBSD." NetBSD supports more than 50 platforms, ranging from old 68K and million instructions per second (MIPS) systems to the newest x86_64 processors from Advanced Micro Devices, Inc. (AMD) and Intel®. Furthermore -- and possibly more importantly -- NetBSD has been ported for use on a massive number of embedded systems.

　　Embedded systems

　　Embedded systems are huge part of everyday life in the 21st century, far outselling traditional computing devices such as desktops, laptops, and servers. From mobile phones to automobiles to cable boxes, you're more than likely using a computer in some aspect of your life. The operating system and software that sit inside these devices is often as important as the traditional engineering decisions that go into their design.
