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.

Sorry I'm new to the networky world of things, could someone explain what TLS and DNS (seen it in settings here and there) are, and the differences between them.
DNS = Domain Name System. This is used to lookup an IP address (e.g. 123.234.54.32) from a domain name (e.g. lemmy.ml). A DNS query is one of the first things your computer does when you visit a site.
Plain DNS is unencrypted, which means that anyone with the ability to read your requests (e.g. your ISP) can see the names of sites that you're visiting.
TLS = Transport Layer Security. This is a protocol that's used to create an encrypted connection between your device and another one, in this case the DNS server. When this is used, the content of your DNS requests is hidden. Your ISP can still see that you're talking to the DNS server, but not what you're saying to it.
TLS also allows your device to cryptographically verify the identity of the DNS server. Without it, someone with the ability to modify your connection could change the responses from the DNS server. That would allow them to send you back the IP address of a server they control, rather than the real servers IP.
