development length is the length that is needed to insert in the concrete so that can easily resist the force that is applied

whereas
anchorage length is the length of bar which is considered to be available when it is bended by some angle and it is provided at the support

similarly, the development length in the column will be the same as that of beam

from the below image you can understand what I m saying about the development length and anchorage length of beam and column
