Just like Windows XP, Windows 7, Windows 8, and Mac OS X, Linux is an operating system. An operating system is software that manages all of the hardware resources associated with your desktop or laptop. To put it simply â the operating system manages the communication between your software and your hardware. Without the operating system (often referred to as the âOSâ), the software wouldnât function. The OS is comprised of a number of pieces: The Bootloader: The software that manages the boot process of your computer. For most users, this will simply be a splash screen that pops up and eventually goes away to boot into the operating system. The kernel: This is the one piece of the whole that is actually called âLinuxâ.
