A Linux distro, or distribution, is a combination of the Linux operating system kernel, program and application software, as well as libraries and documents. When someone installs a Linux distro on their computer, they are essentially getting a party of the essential Linux bits such as a core operating system, command line interface, system libraries, desktop environment and applications.
