What is the difference between update Georeferencing and rectify?

Rectify: Permanently alters the spatial referencing information of a raster dataset by a transformation, which also alters the orientation of the pixels. Update Georeference: doesn’t alter the orientation of pixels, instead it creates a “persisted transformation” with the raster dataset.

What is Georeferencing and rectification?

Georeferencing is the recording of the absolute location of a data point or data points. Georectification refers to the removal of geometric distortions between sets of data points, most often the removal of terrain, platform, and sensor induced distortions from remote sensing imagery.
 

What is geo rectified?

Georectifying — The digital alignment of a satellite or aerial image with a map of the same area. In georectification, a number of corresponding control points, such as street intersections, are marked on both the image and the map.
