Who wrote the Unix operating system?
It certainly was for Ken Thompson and the late Dennis Ritchie, two of the greats of 20th-century information technology, when they created the Unix operating system, now considered one of the most inspiring and influential pieces of software ever written.
What is Unix design?

What was the original name of Unix?

Is Unix used today?
Yet despite the fact that the alleged decline of UNIX keeps coming up, it’s still breathing. It’s still widely used in enterprise data centers. It’s still running huge, complex, key applications for companies that absolutely, positively need those apps to run.

Is Java an operating system?
The Java Platform
Most platforms can be described as a combination of the operating system and underlying hardware. The Java platform differs from most other platforms in that it’s a software-only platform that runs on top of other hardware-based platforms.
