Explanation:

A cell range that is comprised of two or more separate adjacent ranges is known as Non adjacent Range.
A contiguous range of cells is a group of highlighted cells that are adjacent to each other, such as the range C1 to C5 shown in the image above. A non-contiguous range consists of two or more separate blocks of cells. These blocks can be separated by rows or columns as shown by the ranges A1 to A5 and C1 to C5.
