Cyber Fundamentals Block 2 Practice Exam

Which UNIX-like OS was developed by Apple Inc.?

Linux BSD Solaris MacOS

Correct Answer:

MacOS

Explanation:

macOS is the UNIX‑like operating system developed by Apple for its Mac computers. It’s built on a Unix‑like core called Darwin, which comes from BSD Unix, and uses the XNU kernel, a hybrid of Mach and BSD components. Apple combines this foundation with its own user interface and features to create macOS. This distinguishes it from Linux, which is a kernel created by Linus Torvalds and the associated distributions not developed by Apple; from Solaris, which originated with Sun Microsystems (now Oracle); and from the BSD family, which is the Berkeley-derived UNIX lineage that predates Apple’s OS. So, the OS Apple built is macOS.
