What is a camera diaphragm, isn’t it the same as the shutter? I’m starting out as an amateur photographer, and I’m stuck in the lingo.

I’d never heard of a diaphragm on a camera before. Just off the top of my head it sounds like an aperture. And a quick Google seems to agree. If you have a fixed aperture, then there isn’t much to talk about, but a variable aperture is usually a way to mechanically stop some light from getting in. A smaller aperture can sharpen movement and lengthen the field of focus, but darken the overall image. A larger aperture collects more light for dark scenarios, but is a bit harder to focus. The shutter is all or nothing it either blocks all the light or let’s all the light in. It also determines how long the aperture is exposed to light. The aperture determines how much of that light reaches the sensor (or film)
Typically, your settings will be called something like shutter speed and aperture diameter.
