From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hi all - I am learning about Linux and want to see if my understanding is correct on this - the list of major parts of any distro:

the Linux Kernel
GRUB or another bootloader
one or more file systems (gotta work with files somehow, right?)
one or more Shells (the terminal - bash, zsh, etc...)
a Desktop Environment (the GUI, if included, like KDE or Gnome - does this include X11 or Wayland or are those separate from the DE?)
a bunch of Default applications and daemons (is this where systemd fits int? I know about the GNU tools, SAMBA, CUPS, etc...)
a Package Manager (apt, pacman, etc...)

Am I forgetting anything at this 50,000 foot level? I know there are lots of other things we can add, but what are the most important things that ALL Linux distributions include?

Thanks!

One thing I don't know: if C is a compiled language already, what exactly does the C library do?

[–] lseif@sopuli.xyz 5 points 11 months ago* (last edited 11 months ago)

it is a dynamically linked library, meaning its not in the compiled binary, but its assumed to already be on the system. as opposed to a statically linked binary. this lowers the file size of the binaries, because most will use the standard library.

edit: this may not be 100% correct, but its the general idea

Most C binaries usually do not contain everything needed for their execution. It would make them too platform-specific. What most c programs do is that they use standard c library from platform for low-level things and communication with the system like memory allocation or stdin/stdout things, for example.
