What are DNS server, resolver and stub resolver?

https://www.freedesktop.org/software/systemd/man/systemd-resolved.service.html#Description says




Additionally, systemd-resolved provides a local DNS stub listener on IP address 127.0.0.53 on the local loopback interface. Programs issuing DNS requests directly, bypassing any local API may be directed to this stub, in order to connect them to systemd-resolved.




How shall I understand the format of `/etc/resolv.conf`? says




the DNS server and resolver ("stub resolver") can be different, you can pass DNS requests to 127.0.0.53 which pass them to your router for actual DNS (eg it could handle local hosts but pass requests for remote hosts on for full DNS).




What are DNS server, resolver and stub resolver?



I also heard of two kinds of DNS servers (one is called "resolver", and the other I forgot). What do the two kinds mean?



Thanks.

EDIT1: I have had a look at the official Windows drivers for the UX433FA TouchPad, but was not able to make anything of it. I tried installing them on Linux using tools like NDISWrapper, but they do not detect the TouchPad/Numpad hardware, and my understanding of drivers is too limited. ...
