What is NetBSD

                  NetBSD is a free, highly portable UNIX-like operating system that is the most widely used operating system on the current portable platform and can be executed on many platforms, from 64-bit alpha servers to handheld devices and embedded devices. The slogan of the NetBSD program is: "Of course it runs NetBSD". Its simple design, code specifications, and many advanced features make it highly acclaimed in the industry and academia. Due to its simple design and advanced features, it has excellent performance in production and research, and it also has complete source code supported by users. Many programs are easily available through the NetBSD Packages Collection.

History of NetBSD

The first version of NetBSD is NetBSD (0.8), which dates back to 1993. It is a version of the Unix operating system 4.3BSD Lite developed from the University of California, Berkeley. And the first BSD (BSD = Berkeley Software Distribution) designed for Intel 386 CPU: based on the 386BSD system. In the following years, the Berkeley team integrated the patching work based on the 4.4BSD Lite (the last release of the Berkeley team) into the system. The BSD development branch of Unix played a pivotal role in the development of this operating system and had a major impact on it. NetBSD uses a lot of tools, ideas and improvements from the BSD development branch of Unix (such as vi editor, C shell, job control, Berkeley fast file system, reliable signal, support for virtual memory, TCP/IP application tools, Just a few simple examples) These have basically become the standard for all Unix-like environments. These traditional research and development methods and tools are preserved in today's free and commercial BSD systems, especially in NetBSD.

Features of NetBSD

NetBSD is widely distributed across a wide range of hardware platforms and is very portable. It is probably the most portable operating system in the world. The full source code for the NetBSD cores and applications is valid on the supported platforms; see the official website for the NetBSD Project.

The basic features of NetBSD are:

Portability (more than 20 platforms are supported)

High quality and accuracy of program code

Sex

Research and Innovation

The above characteristics also bring indirect advantages. For example, if you only work on a single platform, you may think that your interests are not in terms of portability, but portability has long been one of the quality characteristics of program code: there is no good foundation for writing and organization. It is impossible to support many platforms at the same time, and high-quality program code is the foundation of any perfect and stable software system, so don't worry that only a few people can understand it. This helps to increase the potential of the NetBSD code and the quality of the driver due to architectural and quality issues.

By distinguishing the differences in these NetBSD features, we can see that it is not sufficient to be implemented in only certain aspects. Some systems seem to have such a design philosophy " if it works, it is good ". As far as NetBSD is concerned, it can be described as "unless it is correct, otherwise it will not work." Imagine how many heavyweight and "characteristic" programs have been sadly discarded today; so you will understand why NetBSD avoids this costly situation.
