I just was gifted my first "real" camera, a Sony DSLR-A390 with what appears to be a SAL1855 lens?
I have no idea about apertures or focal lengths, or really anything at all aside from using my phone's camera. Can anyone suggest some good very beginner resources that explain all this?
Pretty sure this is the camera: https://www.dpreview.com/reviews/sonydslra390
Just remember that there's only three choices and they are a trade off
low iso needs a lot of light but is pretty. high iso can be in the dark but is ugly
small aperture (high f/stop) is a tiny hole so everything is in focus, but dark, so you need a lot of light. Large aperture (low f/stop) is a big hole, so you need less light, but only a thin slice is in focus.
fast shutter speed = less blur, but you need more light.
those three are the trade off.

this is from https://tahusa.co/guides-and-tips/basic-iso-shutter-speed-and-aperture/ - but its a good depiction of the idea of the exposure triangle.
That's the first thing, then you work from there.
@timdesuyo Thanks for the links!
So it seems that this lens has quite a few focal lengths, and should allow for a somewhat broad range of shots? I'm just trying to figure out what I have here.
