== NetBSD ==

'''NetBSD''' is a free and open-source [[Unix]]-like operating system descended from the [[Berkeley Software Distribution]] (BSD). It is renowned for its high [[portability]], running on a wide range of hardware platforms from large servers to embedded systems, including many older and uncommon architectures. The project's motto, "Of course it runs NetBSD", reflects this extensive platform support.

== History ==

NetBSD was created in 1993 by a group of developers including Chris Demetriou, Adam Glass, and Charles Hannum, who forked from [[386BSD]] to produce a more portable and cleanly designed system. The first release, NetBSD 0.8, appeared in April 1993. The project later adopted the [[pkgsrc]] package management system, which became a cross-platform package manager used not only by NetBSD but also by other systems such as [[DragonFly BSD]] and [[MINIX]]. In 2023, NetBSD 10.0 was released, incorporating improvements in performance, security, and hardware support.

== Features ==

* '''Portability''': NetBSD supports over 50 hardware platforms, from 32-bit and 64-bit ARM to MIPS, PowerPC, SPARC, and many more. The kernel is structured to isolate machine-dependent code.
* '''pkgsrc''': A large collection of precompiled and source-based software packages, with native support on multiple operating systems.
* '''Security''': Includes features like [[Kernel authorization]] (Kauth), [[Veriexec]] for file integrity, and [[Address space layout randomization]] (ASLR).
* '''Licensing''': Released under a permissive [[BSD license]], allowing commercial and non-commercial use with minimal restrictions.
* '''Virtualization''': Support for [[Xen]] hypervisor as a host or guest, and binary compatibility layers for [[Linux]] and other Unix-like systems.

== Related Projects ==

* [[OpenBSD]] – a sister project focused on security and code correctness.
* [[FreeBSD]] – another BSD derivative, emphasizing performance and ease of use.
* [[DragonFly BSD]] – a fork from FreeBSD with a focus on scalability.
