What is Linux?
Linux. Itâs been around since the mid â90s, and has since reached a user-base that spans industries and continents. For those in the know, you understand that Linux is actually everywhere. Itâs in your phones, in your cars, in your refrigerators, your Roku devices. It runs most of the Internet, the supercomputers making scientific breakthroughs, and the world\'s stock exchanges. But before Linux became the platform to run desktops, servers, and embedded systems across the globe, it was (and still is) one of the most reliable, secure, and worry-free operating systems available.
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. The kernel is the core of the system and manages the CPU, memory, and peripheral devices. The kernel is the âlowestâ level of the OS.
Daemons: These are background services (printing, sound, scheduling, etc) that either start up during boot, or after you log into the desktop.
