What are camera sensor hot spots and how are they fixed, or at least compensated for? How do they occur?

All sensors leave the production line with dead pixels and hot spots. Some number of these is suitable for a sensor to pass quality control and be sold. Over time, sensors develop more hot pixels and dead pixels. Pixel mapping, a common feature on DSLR cameras, allows the camera to identify and compensate for dead and hot pixels.
