What is NetBSD?

NetBSD is a highly portable, secure, and open-source UNIX-like operating system that can be used on many platforms, from large server systems to desktop systems, portable devices, and integrated systems.

What is the NetBSD Operating System?

Its clean design and advanced features make it perfect in both production and development environments, and the source code can be freely distributed under a business-friendly license.

NetBSD has been developed and supported by a large and active international community. Many applications are easy to use through pkgsrc, the NetBSD Package Collection.

Starting with the UNIX system, the product of years of development from the sixth edition is a mature operating system.

NetBSD is used for many uses from server to client, but although it is perfect as a firewall or server, it also works perfectly for all other uses you want to give.

Name Source

The name BSD is the clear recognition of its legacy as a derivative of 4.4BSD and 386BSD. Contributors primarily communicate via e-mail and online chat systems; many of them have never met in person.

A source code management system called CVS is also used, which helps many developers work independently in the same source code tree. The Internet was the technology that made NetBSD possible. That’s why the NET in his name was chosen as a tribute to the Internet.


NetBSD is distributed in three ways: the formal version, the maintenance branch, and the ongoing.

Official versions are periodically done and include proven binaries, source code, and installation tools. Maintenance lines often provide bug and security fixes and minor improvements.

The current version is a nightly distribution for people who want the latest version of the software and are not bothered by occasional errors, with the latest improvement in the code.


If a project has no goals, it has no end. Fortunately, the NetBSD Project has enough goals to keep you busy for a long time.

  • It provides a fast, stable, and well-designed BSD system.
  • Avoids prohibitory licenses.
  • It provides a portable system that works on many hardware platforms.
  • It works with other systems.
  • It remains true to Open Source standards as much as possible.


NetBSD is based on a wide range of free software distributions, including, but not limited to 4.4BSD Lite, Net/2 (Berkeley Networking Release 2) MIT X Window System, and GNU software from the University of California-Berkeley.

NetBSD is currently focused on providing a stable, cross-platform, secure, and research-oriented operating system.

It is designed and well-organized with the priority of writing quality code and designed taking into account standards (POSIX, X/Open, and more related others): Evidence of this good design is its wide portability.


Some advantages over other operating systems:

  • Special focus on code quality and portability. Moved to 56 architectures.
  • It is often a pioneer in the implementation of new technologies (eg IPv6).
  • High security and stability. It was used in NASA.
  • Fast and reliable BSD FFS (Fast File System) file system.
  • Security: IPsec support.
  • XEN Dom0: Native support for XEN virtual machines since version 3.0.

Hardware Requirements

Due to the portability of the system and the high quality of the source code, the operating system supports a large number of architectures that make the hardware requirements almost the newest from the oldest. Because it works successfully on many machines from the oldest to the newest. It is a modern system that provides more portability in every update.


There are several versions of NetBSD, including:

  1. 0.8: It is the first version of the system derived from the UNIX 4.3BSD Lite operating system.
  2. 0.9: Many improvements and bug fixes are included. This was still a platform PC version only after trying to add support to other architectures.
  3. 1.0: The advanced file system that makes it faster and support for 64-bit file size came from 4.4BSD-Lite.
  4. 1.1: Added links for DEC Alpha, TT/Falcon030 Atari and mvme68k systems, dual emulation setup, and general audio.
  5. 1.2: Ports are introduced for ARM and Sharp X68k systems.
  6. 1.3: Added support for ISA Plug and Play PCMCIA, ATAPI, and APM, and FAT32 file systems.
  7. 1.4: Added USB support for Macintosh systems.
  8. 1.5: IPv6 and IPsec added to the network stack.
  9. 1.6: Unified Cache Buffer (UBC), which combines the file system and virtual ram caches of the data file, is introduced.
  10. 2.0: It contains more than 5,000 packages that support 54 different architectures as well as security enhancements.
  11. 3.0: The new is the newly added support for the iyonix and hp700 platforms. It now supports file systems larger than 2 terabytes.
  12. 4.0: Added support for Xen 2.0, Bluetooth, security system enhancements.
  13. 5.0: A new implementation of the new transactional file system 1:1 thread, FFS (“Fast File System”), has been added.
  14. 5.0.1: This is the final stable version of this system where security continues to be updated.
  15. 6.0: Added new subsystem and NPF traffic filtering features for Thread-local and Logical Unit Manager functionality, Flash devices, and NAND controller.
  16. 7.0: Accelerated support for Intel and Radeon devices on x86 has been added via a port of Linux 3.15 DRM/KMS code. In addition, Lua kernel scripting, blacklistd, NPF enhancements, Multiprocessor ARM support, and two new ARM cards (Raspberry Pi 2, ODROID-C1) have been added.
  17. 8.0: USB 3.0 host controller and speed ratios have been improved. The Melt and Specter vulnerability have been reduced for Intel and AMD CPUs. Added support for more ARM cards, including a UEFI bootloader, NVMe driver, nouveau driver for Nvidia graphics cards, Raspberry Pi 3.
  18. 9.0: Updated DRM to Linux 4.4, added support for Intel graphics up to Kaby Lake, and included. Improvements for AArch64, ARMv7-A have been improved. Hardware virtualization support for QEMU has been improved through NVMM (Virtual Machine Monitor).


You have to finalize the most relevant data of this free operating system:

High architectural portability stands out in the system since there is no problem in the system. Requirements are not available, this allows each version to run on older computers and modern computers, where it is about making the operating system more compatible with other machines.

Given the high quality of the source code, the NetBSD operating system has a high level of security, making it the safest and most stable feature in the world. It is very effective for private or firewall use.

It has a great effect for different uses, ideal for research and work environments.

Due to its high portability, it is a recommended system for all users, from beginners to computer experts.
