Answers
a) WORKBOOK:-
In Microsoft Excel, a workbook is a collection of one or more spreadsheets, also called worksheets, in a single file. Below is an example of a spreadsheet called "Sheet1" in an Excel workbook file called "Book1." Our example also has the "Sheet2" and "Sheet3" sheet tabs, which are also part of the same workbook.
b) DATA VALIDATION
In computer science, data validation is the process of ensuring data has undergone data cleansing to ensure they have data quality, that is, that they are both correct and useful. It uses routines, often called "validation rules", "validation constraints", or "check routines", that check for correctness, meaningfulness, and security of data that are input to the system. The rules may be implemented through the automated facilities of a d ata dictionary, or by the inclusion of explicit application program validation logic of the computer and its application.
c) IF Functions
The IF function is one of the most popular functions in Excel, and it allows you to make logical comparisons between a value and what you expect. So an IF statement can have two results. The first result is if your comparison is True, the second if your comparison is False.
d) WORKSHEET
A Worksheet is a collection of cells organized in rows and columns. It is the working surface you interact with to enter data. Each worksheet contains 1048576 rows and 16384 columns and serves as a giant table that allows you to organize information.
e) CELL REFERENCE
A cell reference refers to a cell or a range of cells on a worksheet and can be used in a formula so that Microsoft Office Excel can find the values or data that you want that formula to calculate. In one or several formulas, you can use a cell reference to refer to: ... Data contained in different areas of a worksheet.
