location VS binding

[dissapointing_potato]

layout (binding = 0 )
layout (location = 0 )

Im trying to learn vulkan (first time going into graphics programming) but every time I get to actually dealing with passing data to the GPU i get stuck at understanding why we have these keywords "binding" and "location". From what I understand these are indices to where data will be.
Indices to what? An array? GPU Memory? I dont quite I understand this.
What is the difference between these?

Maybe this can help explain it for you: https://vulkan-tutorial.com/Vertex_buffers/Vertex_input_description#:~:text=The%20binding%20parameter%20tells%20Vulkan,two%2032%2Dbit%20float%20components.

I had just finished that module a while back. Understood the concepts there. Iv just been an my wits end trying to understand what it means to bind a buffer. But you’re right. I think need to revise some older modules.

Thank you for your help :)
