Meaning and Definition of Spreadsheet Package
A Package can be defined as software written to perform a particular task.
Therefore, a Spreadsheet Package is a program that enables the computer user to carry out calculation-related tasks. Spreadsheets are majorly used for organizing and analysing numeric data. They were designed to replace the pencil, calculator and the writing pad. It is widely used in diverse range of disciplines like Engineering, Mathematics, Science, Accounting, etc.
Examples of Spreadsheet Package
- Lotus 1-2-3
- Microsoft Excel
- Quattro pro
- Easy Calc
- Apple numbers
- Freeware spreadsheet program
NOTE: For the purpose of this lesson, our focus shall be on Microsoft Excel because it is user-friendly, flexible and contains more advanced features.

Spreadsheet Features and Terminologies
To fully understand and use a spreadsheet package, one must be used to some terminologies. These terminologies include;
A Row is a horizontal line of cells which runs from left to right in a worksheet. They can be identified by the numbers at the left-hand-side of the work sheet. They are numbered from 1, 2, 3 to 1,048,576 in Excel 2007, 2010, 2013 & 2016.
A Column is a vertical line of cells in a worksheet usually identified by letters across the top of the sheet. There are about 16,384 columns in Excel 2007, 2010, 2013 & 2016.
A Cell is the intersection of a row and a column. The highlighted rectangle on the cell is the cursor but is known as ‘cell pointer’ which enable users to move around the sheet. They can be identified by the combination of column header (e.g. ‘A’) and the row header (e.g. ‘1’) to give cell A1.
The Active Cell
The active cell is the cell that contains the cell pointer, while the active worksheet is the worksheet where the cell pointer is currently located.
The worksheet (also known as spreadsheet) is the working area of the package where entering of data and calculations are handled. It consists of rows, columns, cells and a cell pointer where data are actually entered and manipulated.
This can be simply defined as a collection of worksheets. Each workbook contains many worksheets just like a normal single book with a number of pages.
A Chart is a graphical representation of data that enables you to understand the data at a glance. Examples of Charts include Column (histogram), Pie chart, Bar Chart, Line Chart, Surface, Doughnut, etc.
A group of highlighted cells in a worksheet is referred to as a Range.
This is a small black square at the corner of selected cells. The cursor changes to a black cross when moved to it.
This is an animated border that appears around a selected cell that has been cut or copied. Press the ESC key to cancel a moving border.

Definition of a Worksheet
A worksheet can be defined as the working area of the program where entering of data and calculations are handled. It consists of rows, columns, cells and a cell pointer.
Starting Excel Worksheet
This entails the following:

Labels are made up of texts that are entered into the active worksheet. Examples are letters of alphabets (A-Z)
Numbers/values consists of numerals 0 – 9
Formulas are mathematical expressions which return calculated value.
A typical example of data entry is shown below:
