17. Explain the concept of cell referencing along with its various types.

Ans. In Excel, there are three types of cell references: relative, absolute, and mixed. Each one has a specific purpose, and knowing how to use each type is key to creating accurate formulas and working with data.

There are three types of cell referencing: 

(1) Relative Referencing.

(2) Absolute Referencing.

(3) Mixed Referencing.

(1) Relative Referencing: Relative Every relative cell reference in formula automatically changes when the formula is copied down a column or across a row. As the example illustrated here shows, when the formula is entered (= B4 — C4) in Cell D4 then this formula copied in D5 then it will change into (= B5 — C5) related to the cell.  

(2) Absolute Referencing: Absolute An absolute cell reference is fixed. Absolute references do not change if you copy a formula from one cell to another. Absolute references have the dollar sign ($) like $S$9. As the shows, when the formula =C4*$D$9 is copied from the row, the absolute cell reference remains as $D$9. ‘  

(3) Mixed Referencing:  Mixed A mixed cell reference has either an absolute column and a relative row, or an absolute row and a relative column, e.g. $A1 is an absolute reference to column A and a relative reference to row 1. 

As a mixed reference is copied from one cell to another, the absolute reference stays the same but the relative reference changes.
