Who invented Unix?
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.
Is Unix 2020 still used?
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.
