assign, associate and attach

assign, associate and attach

Hi,
I'm confused about assign, associate and attach and have a few questions:
1- What is difference between "Assign Asset to Site" and "Associate Asset to Site"? (Figures 1 and 2)
2. What is difference between "Associate Asset to Asset" and "Attach Asset to Asset"? (Figures 3 and 4)
I also have an idea. The user experience of these sections is very confusing. It is better to present these sections in a single and integrated view.
Thanks.
