Based on the provided reference, the question seems to be missing context. "OST" is not defined. Assuming "OST" is irrelevant and the question is actually about "BSD", here's a refined question and answer:
What is BSD (Berkeley Software Distribution)?
BSD, or Berkeley Software Distribution, refers to a series of UNIX-like operating systems descended from UNIX variants developed at the University of California, Berkeley, Department of Electrical Engineering and Computer Science. Specifically, the development was originally led by Bill Joy.
Key Aspects of BSD
Here are some key aspects related to BSD:
- Origin: BSD originated from the University of California, Berkeley.
- UNIX-like: BSD operating systems are Unix-like, meaning they share characteristics with the original UNIX operating system.
- Active Development: Several BSD-derived operating systems remain under active development to this day.
- Bill Joy: Bill Joy played a key role in the initial development of BSD.
Examples of BSD-based Operating Systems
While the reference doesn't explicitly list examples, some well-known operating systems derived from BSD include:
- FreeBSD
- OpenBSD
- NetBSD
- macOS (Darwin, the core of macOS, is BSD-derived)
