Detailed explanation-1: -Cell Reference: A cell reference is the name of the cell that is found by combining the Column Letter with the Row Number. For example the cell in Column “C” in Row “3” would be cell C3.

Detailed explanation-2: -A cell reference, or cell address, is an alphanumeric value used to identify a specific cell in a spreadsheet. Each cell reference contains one or more letters followed by a number. The letter or letters identify the column and the number represents the row.

Detailed explanation-3: -Cells are the boxes you see in the grid of an Excel worksheet, like this one. Each cell is identified on a worksheet by its reference, the column letter and row number that intersect at the cell’s location. This cell is in column D and row 5, so it is cell D5. The column always comes first in a cell reference.

Detailed explanation-4: -If you want to maintain the original cell reference when you copy it, you “lock” it by putting a dollar sign ($) before the cell and column references. For example, when you copy the formula =$A$2+$B$2 from C2 to D2, the formula stays exactly the same. This is an absolute reference.
