There are lots of great descriptions of the difference between Uniform and Attribute variables online. Here's a good description that found

Quote

The difference between attribute and uniform variable is that attribute variables contain data which is vertex specific so they are reloaded with a new value from the vertex buffer for each shader invocation while the value of uniform variables remains constant across the entire draw call. This means that you load the value before making the draw call and then you can access the same value in each invocation of the vertex shader. Uniform variables are useful for storing data such as lighting parameters (light position and direction, etc), transformation matrices, texture objects handles and so on.
