NetBSD Logo — NetBSD is an operating system family Unix (not in itself be called a “Unix”, as this is a trademark of AT&T but is referred to as its “UNIX” or “derivative of UNIX”) open source and free, and December 2008, available for more than 56 platforms hardware. The design and advanced features make it ideal for many applications. NetBSD has emerged as the efforts of a large number of people who aim to produce a like operating system Unix freely accessible and distributable.
The first version of NetBSD (0.8) dates from 1993 and comes BSDLite OS 4.3, a version of UNIX developed at the University of California Berkeley, and 386BSD system, the first BSD ported to Intel 386 CPU. NetBSD takes its name from the version of the BSD 4BSD/Tahoe-Net/1 because of them developed the protocol TCP / IP, the most important protocol on the Internet. NetBSD, like FreeBSD, is derived from the latest version of the BSD, the 386BSD 0.1. The first release of NetBSD (version 0.8) saw the world on April 20, 1993.
NetBSD is based on a variety of freely distributed software that includes, among others, to 4.4 BSD Lite from the University of California-Berkeley, Net / 2 (Berkeley Networking Release 2) the X Window System from MIT and software GNU. NetBSD currently is focused on providing a stable operating system, platform, security-oriented research. It’s designed with a priority to write quality code and well organized, and taking into account also the fulfillment of standards (POSIX, X / Open and more relevant): good test of this design is its wide portability. This is a mature operating system, the product of years of development (the BSD sources are about the year 1977), and based on the system UNIX sixth edition.
