Features and Terminologies in Spreadsheets

1. Row:
   A horizontal line of cells in a spreadsheet, typically identified by a number (e.g., Row 1, Row 2). Rows are used to organize data vertically.
2. Column:
   A vertical line of cells in a spreadsheet, identified by a letter (e.g., Column A, Column B). Columns organize data horizontally.
3. Cell:
   The intersection of a row and a column, a cell is the basic unit where data is entered (e.g., A1 refers to the cell in Column A and Row 1).
4. Worksheet:
   A single spreadsheet page that contains rows and columns. A workbook may contain multiple worksheets.
5. Chart:
   A visual representation of data, such as a bar graph or pie chart, used to illustrate trends and comparisons.
6. Data Range:
   A selection of two or more cells in a spreadsheet. It can be a single column, a single row, or a block of cells used for calculations or chart creation.

Practical: Loading and Using an Existing Spreadsheet

• Step 1: Open the spreadsheet software (e.g., Microsoft Excel).
• Step 2: Navigate to the “File” menu and select “Open.”
• Step 3: Browse to find the existing spreadsheet file and click “Open.”
