1. Definitions

2. Cell: Cell: Space in the intersection of a column (vertical division) and a row (horizontal division). Row: Row: A row runs horizontally in an Excel worksheet and are identified by a number in the row header. Each spreadsheet has 65, 536 rows. Column: Column: Columns run vertically on a worksheet and each one is identified by a letter in the column header. Each spreadsheet has 256 columns.

3.  Label:  Label: Each sheet label shows a workbook, so you can work simultaneously in many spreadsheets; without minimizing the program.  Macro:  Macro: A macro in computer science is a rule or pattern that specifies how a certain input sequence (often a sequence of characters) should be mapped to an output sequence (also often a sequence of characters) according to a defined procedure. where the idea is to make available to the programmer a sequence of computing instructions as a single program statement, making the programming task less tedious and less error-prone.

4. Template: Template: It is a task-oriented Excel spreadsheet that already has the necessary and appropriate formulas programmed in and professional-looking formats laid out for you. This saves you time, while providing you with the analytical wisdom and presentation style of the pros. Worksheet: Worksheet: A worksheet (also known as a spreadsheet) is a collection of cells on a single "sheet" where you actually keep and manipulate the data. Range: Range: It is a group or set of cells. A cell is also considered a range. Relative reference: Relative reference: The formulas are adjusted automatically to give reference to the corresponding columns. This is called relative reference.

5. Absolute reference: Absolute reference: If we write the formula =B2-B10 and extend it to the following columns, this will give wrong references like =C2-C10 and =D2-D10. So to avoid this, we use the absolute reference =$B$2-B10. Now when we extend, the formulas are correctly filled as =$B$2-C10 and =$B$2-D10. The $ symbol represents the absolute reference. So $B$2 is the absolute value of the cell B2. Formatting cells Formatting cells: When you enter data into a cell in Excel, it is handled differently depending on what type of formatting you have assigned to the cell. All of these choices are available when you highlight/select the cell(s) you want to format, then go to the Format menu and choose Cells.
