Strictly speaking, Linux is not an Operating System, instead Linux is a kernel.
Kernel provides access to computer hardware & access control to resources.
- Describe who will use the resource, for how long and when.
- Linux kernel in itself is useless without other features.
Linux Distribution = Kernel + GNU Application Utilities + GUI Apps + Utilities + Application Software + Software Development Tools + Linux Installation Scripts + Shell + Post Installation Management Tools
Linux Torvalds (in 1921) created Linux, when he was working with Minix (educational version of Unix).
Linux was a kernel developed by Linus.
