Texture Textures add detail at the shader level. These perform some conversion function examples in Cycles would be the Math node, or the Blackbody node , or provide access to variables such as the Geometry or Texture Coordinates nodes Material A material is a collection of shader s that you apply to a model to define how it is shaded.
Not everyone uses these terms in such a way. For example most places that use PRman or a RenderMan compliant renderer will refer to materials as shaders.
But like Jeremy said, things are diferent in Mray. I guess its all realtive to what renderer you are dealing with. I think this is probably the most universally accepted definition.

Continued use of the site after the effective date of a posted revision evidences acceptance. A collection of functions and textures that define the appearance of a specific surface. Close, the shader is doing calculations on the surface. What a shader basicly does is take the physical surface it is applied to, the lights effecting the surface, and the eyepoint camera. It then takes the textures and whatever other parameters and functions you give to the shader, and calculates exactly what the surface is supposed to look like at each given pixel in the final rendering.
The shader uses the textures you give to it in the process of making these calculations to determine what the surface looks like in the final image, but typically the shader does not do any calculations on the texture itself. Also, shaders are quite unlimited compared to textures alone. A texture can only do so much. The texture image alone cannot react to the lights in the scene, and has no animatable parameters, unless you count loading a set of frames as being animatable.
Shaders on the other hand can react to lights, your camera, or really anything in your scene that you want to have effect your shader, can modify the geometry they are applied to entirely, and are completely animatable.
Except for being able to load a series of Frames or maybe doing some morphing or compositing tricks, textures are pretty static. Shaders on the other hand can be highly dynamic. Another thing, textures, no matter how big their resolution is, will fall apart if the camera gets close enough to the surface; you will start seeing individual texels. Well you are right about that. Shaders are hard to come by, but if yo search a bit, they can be found.
Search google. I think the problem is that artists have this bizarre propensity to want to keep every little thing they make for themselves, while still expecting music and software to be either free or dirt cheap, oddly enough. You know, this site is very active. If every artist here made an effort to produce just one free public shader a month for their respective software, each app represented on this site could have literally thousands of, hopefully, quality, free shaders available in about 6 months time.
In order to get a subscription for 30 days or 14 days or whatever, a user has to produce one quality asset for the depot. Do you mean that only ppl who know programing will be able to have the free shaders?
