The origins of FreeBSD

In the computer World, UNIX has always been a high-end platform. A few years ago, it was only possible to access them in the specialized rooms of large institutions, and even smaller institutions could not afford to buy UNIX workstations. Only a few users have access to and use of UNIX, and fewer computer professionals can manage and maintain UNIX systems, leaving Unix with a veil of secrecy that, in front of ordinary users, is an unwieldy and expensive operating system. However, this has changed since the advent of the free Unix system running on PCs.

In fact, today's UNIX cannot be said to be a single operating system, it includes a wide variety of high-end HP, Sun servers, as well as medium and low-end UNIX systems running on Intel platforms. UNIX is no longer an operating system that ordinary users are expected to have, and every person who loves Unix can install a UNIX system in their PC, learn it, and use it. Small and medium-sized enterprises can also use a PC server to run the UNIX system, the full use of the powerful UNIX system processing capacity.

FreeBSD is a freely available UNIX system running on an Intel platform that can be obtained free of charge from the Internet. And it has extremely excellent performance, so that it has been computer researchers and network professionals recognized. As a result, not only professional researchers use it as a personal UNIX workstation, many businesses, especially ISPs (Internet service providers), use high-end PC servers running FreeBSD to provide network services to many of their users.

The origins of FreeBSD

Since the creation of UNIX by At&t Bell Lab researchers in 1969, UNIX has evolved and become a mainstream operating system. Although the current Windows family has occupied the domain of desktop computers, in which Windows NT servers have been recognized by some users in the domain of network servers, Unix still has an irreplaceable role in high-end workstation and server domains. Especially as a inter NET Server, Unix's high performance, high reliability, and highly scalable capabilities are still not being replaced by other operating systems.

Although Unix was created by at&t, its popularity was not entirely attributable to At&t's own credit. Modern UN IX is not an individual product of a manufacturer, and it has evolved in many different versions during its long development. Only the rich and diverse, so that Unix has a strong vitality. FreeBSD is one of the many UNIX branches of a very good, its development history is also very long, is a well-known BSD Unix successor, so to understand the history of FreeBSD development, first of all to understand the development of the UNIX process.
