What is Linux?

Response:
Linux is a family of open-source Unix-like operating systems that are based on the Linux kernel. The Linux kernel was first released on September 17, 1991 by Linus Torvalds. Linux was originally developed for personal computers based on the Intel X86 architecture, but has since then been ported to more platforms than any other operating system. Popular Linux distributions include Debian, Fedora, Red Hat and Ubuntu.
