It sure can be. We "dial" numbers on telephones. When we're done with a call, we "hang up". There's a button on the phone for the "operator".
I suppose we can all agree on selective double standards.
"Shutter" is already a hangover from the days when the exposure had to be ended manually by inserting something into the light path.

I have one of the old glass plate cameras, i was given it last week and its a museum piece worth $1500 ama zing peice of kit where you load 6 plates into it and they fold down after the exposure.
I work in Engineering and we use a lot of design methods which are not scientifically precise
This has nothing to do with wrong things, especially when the correct things are easier and more productive, and, most of all, help creativity.
Noise tends to increase with increasing ISO.
Could you please demonstrate how increasing ISO affects noise?

I could show pics at iso 100 without noise and pics at 6400 with noise. I’m not sure I understand what you mean by “demonstrate.” Unless I missed context earlier…which with a thread this long is quite possible…LOL

With the same exposure?

The question is, where'd that noise come from? Was it due to a lack of exposure, or a the high ISO setting?

Actually, I think it would be useful, and gives a possibility to discuss the reason for the difference in noise.

Did you change the scene light? Use an ND filter? Then it is not the same exposure.
In all my tests, the same exposure showed equal or less noise with higher ISOs (same scene lighting).
I cannot believe I am reading this. You can never hope to educate yourself about anything, without a good textbook, with the emphasis on good.
A beginner will learn faster without frustration if he/she has read about some basic technical/artistic concepts first. A book written by a reliable author is the best place to start. Not the contradictory word of internet.
Noise tends to increase with increasing ISO. I guess the beginner needs to know what happens when you move the ISO dial.
Here is an image taken at ISO 51200. See the difference in the noise between white horse and background? Same ISO. Why?

The answer is yes.
The high iso revealed the noise that’s there due in part to the insufficient exposure. But holding the iso lower and raising the ‘exposure’ in post would reveal the same (or often worse) noise.

I copied and pasted this information from an expert photographer ,so it must be right .🙄🤨
so are you telling me he is wrong ?

- exposure - amount of light that struck the sensor per unit area while the shutter was open
optimal exposure - the maximum exposure within dof and motion blur requirements without clipping important highlights.
under exposed - more exposure* could have been added with the DOF and blur constraints still being met without clipping important highlights
Those are the definitions I choose to use. Other people might choose to use different definitions.
Some people define exposure as meaning how light or dark an image looks. But then their heads begin to spin when I tell them that I can change the image lightness in camera while keeping the exposure* constant 🙂
* exposure - amount of light that struck the sensor per unit area while the shutter was open
** optimal exposure - the maximum exposure* within dof and motion blur requirements without clipping important highlights.

You can find the answer at Why Are My Photos Noisy?

I assume you changed the scene light and therefore changed the exposure (the amount of light reaching the sensor).
