Microsoft Excel is an electronic spreadsheet program.You might of heard the terms "spreadsheet" and "worksheet". People generally use them interchangebly. To remain consistent with Microsoft and other publishers the term worksheet refers to the row-and-column matrix sheet on which you work upon and the term spreadsheet refers to this type of computer application.
In addition, the term workbook will refer to the book of pages that is the standard Excel document.The workbook can contain worksheets,chart sheets, or macro modules.
The Workbook
Most of the Excel screen is devoted to the display of the workbook. The workbook consists of grids and columns. The intersection of a row and column is a rectangular area called a cell.
The workbook is made up of cells.There is a cell at the intersection of each row and column.A cell can contain a value, a formula, or a text entry. A text entry is used to label or explain the contents of the workbook.
A value entry can either be a constant or the value of a formula. The value of a formula will change when the components (arguments) of the formula change. The appeal of spreadsheet programs is the ability to change one value and watch all other values that depend on that first value automatically change when the spreadsheet is recalculated.
