Excel’s serial number data storage allows the COUNT function to accurately tally both times and dates. | The COUNTA function counts all values in a cell, whether they be integers, dates and times, text, Boolean values (TRUE and FALSE), or even error values, because it is a “count all” function.

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.
