descriptor
A small handle that tells a shader where to find a resource like a texture or buffer.
A shader running on the GPU can't just reach out to memory; it refers to resources through descriptors, which bind a specific texture, buffer, or sampler to a slot the shader expects. Setting up the right descriptors is how you connect your data to the code that uses it. microZeus refers to 'descriptor-backed uniforms' — shader constants supplied this way.
