a Unix-like operating system that is derived from Berkeley Software Distribution (BSD)
"Many developers choose OpenBSD as their preferred Unix-like operating system because it is derived from Berkeley Software Distribution and prioritizes security."
The name OpenBSD is a straightforward combination of the word "open," referring to its open-source nature, and "BSD," which stands for Berkeley Software Distribution. This term was created to distinguish this specific version from other derivatives while highlighting its commitment to openness.
