Without the operating system (often referred to as the=20 =E2=80=9COS=E2=80=9D), the software wouldn=E2=80=99t function. The OS is comprised of a number of pieces:=20 The Bootloader: The software that manages the boot process of your=20 computer. For most users, this will simply be a splash screen that pops up= =20 and eventually goes away to boot into the operating system. The kernel: This is the one piece of the whole that is actually called= =20 =E2=80=9CLinux=E2=80=9D. The kernel is the core of the system and manages t= he CPU, memory,=20 and peripheral devices. The kernel is the =E2=80=9Clowest=E2=80=9D level of= the OS. Daemons: These are background services (printing, sound, scheduling,=20 etc) that either start up during boot, or after you log into the desktop. The Shell: You=E2=80=99ve probably heard mention of the Linux command l= ine.=20 This is the shell =E2=80=93 a command process that allows you to control th= e=20 computer via commands typed into a text interface.

It is commonly referred to as the X server or just =E2=80=9CX= =E2=80=9D. Desktop Environment: This is the piece of the puzzle that the users=20 actually interact with.
