What Is a BSD Operating System?

BSD (Berkeley Software Distribution, Berkeley Software Suite) is a Unix-derived system. It was created by the University of California, Berkeley in the 1970s.

BSD (Berkeley Software Distribution, Berkeley Software Suite) is a Unix-derived system, pioneered by the University of California, Berkeley in the 1970s. BSD is used to represent the various suites derived from this.

BSD is often used as a workstation-level Unix system. This is due to the very loose BSD license. Many computer companies established in the 1980s have benefited from BSD. Well-known examples are DEC's Ultrix and Sun. SunOS. In the 1990s, BSD was largely replaced by System V4.x and OSF / 1, but its open source version was adopted, which promoted the development of the Internet.

BSD version

In June 1986, 4.3 BSD was released. This version is mainly to improve performance of many new contributions of 4.2BSD, the original 4.1BSD is not well coordinated. Prior to this version, the TCP / IP implementation of BSD was quite different from the official implementation of BBN. After several months of testing, DARPA believes that 4.2BSD is more suitable, so it is reserved in 4.3BSD. (See en: History of the Internet)

After 4.3BSD, BSD gradually abandoned the old VAX platform. The Power 6/32 platform (codenamed "Tahoe") developed by Computer Consoles Ltd. seemed promising at the time, but was soon abandoned by their developers. However, the 4.3BSD-Tahoe ported in June 1988 performed well. BSD will separate machine-dependent and machine-independent code, laying a good foundation for future system portability.

So far, all BSD versions have been mixed with proprietary AT & T Unix code, so continued use requires a license from AT & T. The source code license was very expensive at the time, and several other organizations were interested in a separate version of the network code, completely independent of AT & T, so it was not subject to the license. In June 1989, Networking Release 1 (Net / 1) was born. It can be used without AT & T authorization, and can be freely redistributed under the BSD license.

In early 1990, 4.3BSD-Reno was launched. This version is an interim version of the 4.4BSD early development. Using this version is nicknamed a gamble, because Reno is the Nevada casino Renault.

BSD's open source descendants

Different BSD operating systems can be applied to multiple hardware architectures for different purposes and users. BSD is often seen in government agencies. Although the following BSD functions may not be unique, each BSD has gradually gained a good reputation in its own field, some focus on performance, while others have a strong reputation for security.

BSD system management

Through the update of the mirror image in the BSD server, rapid deployment and maintenance of the IT system is achieved, and all terminal application software is also updated in real time, which truly achieves standardized management.

Centralized data storage

The BSD solution centrally stores the data scattered on the terminal on the server, completes the real-time backup of the data, and implements the centralized management of the data from the physical architecture, eliminating data loss and leaks caused by misoperation, terminal damage, and malicious operations.

BSD system eliminates viruses

The BSD solution eliminated the hard disk of the terminal, and the virus completely lost the existing media. The files on the BSD server side are stored in a mirror mode, and viruses cannot invade. At the same time, the server side is isolated from the external network, which completely eliminates the hidden danger of server-side infection.

BSD system terminal zero maintenance

The BSD solution uses a terminal that can automatically restore to the initial state of the administrator's configuration system after each restart. This achieves "zero maintenance" of the system of the huge terminal, greatly improving the IT maintenance efficiency and helping IT managers Free from technical repetitive work, have more time and energy to think and implement strategic issues related to the business.

Reduce total cost of ownership

Streamline equipment to improve efficiency

With the BSD solution, the terminal no longer installs hard disks, streamlining hardware investment and improving server operating efficiency.

Reduce system operation and maintenance costs

Through the BSD solution, the quality and management level of the IT management team have also been greatly improved, streamlining labor costs, improving work efficiency, and reducing coordination costs caused by IT system issues between enterprise departments.
