glGenBuffers creates regular buffers for vertex data, etc.

glGenFrameBuffers creates a framebuffer object primarily used as render targets for offscreen rendering.

glGenRenderBuffers creates a renderbuffer object that are specifically used with framebuffer objects for any depth-testing required.

There's a difference between plain old buffers and frame buffers and render buffers (used in offscreen rendering). The overall functionality of those "glGen__" functions is the same, but they just generate different kinds of buffer object names.
