OpenGL will store the information on the graphics card, and it will return an ID associated with that texture for us to place inside an unsigned integer. Also, as seen with textures, the frame buffer ID of 0 (zero) is reserved by OpenGL and is used to unbind the current frame buffer.

WebRenderbuffer Objects are OpenGL Objects that contain images. They are created and used specifically with Framebuffer Objects.They are optimized for use as render targets, while Textures may not be, and are the logical choice when you do not need to sample (i.e. in a post-pass shader) from the produced image.
