It is sometimes required for two users to work on the same system. In such a situation either of the two options – Switch User or the Log Off option can be used.   In case the Log Off option is used then the first user can Log Off and the second user can only then Log in. This means that the programs of the first user are closed and the windows session ends for the first user. But if the first user does not want to close his windows session and needs to resume his work after the second user has completed his task, then the Switch User option should be used.

With relative cell addressing, when you copy a formula from one area of the worksheet to another, Excel records the position of the cell relative to the cell that originally contained the formula. This is the default mode of referencing in a spreadsheet. Absolute referencing, on the other hand, implies that the coordinates of a cell are not changed when a formula is copied from one cell to another. To make a cell address an absolute cell address place a dollar sign in front of both the row and column identifiers.

For example, if the formula =A1+B1 is copied from cell C1 to cell C3, then it automatically changes to =A3+B3. But if the formula =$A$1+$B$1 is copied from cell C1 to cell C3, then it remains unchanged. The dollar sign locks the cell location to a fixed position. Therefore, when it is copied and pasted it remains exactly the same.

Charts are useful as they are an excellent tool to present data in a worksheet in a visually appealing format which aids in analyzing and comparing data. Three chart types available in Excel are:

1.      Pie Chart – It shows the proportional size of data that make up a data series and is useful when we want to emphasize a significant element.

2.      Column Chart – A column chart shows data changes over a period of time or illustrates comparisons among items.

3.      Bar Chart – It illustrates comparisons among individual items. Categories are organized vertically, values horizontally to focus on comparing values and to place less emphasis on time.

1. Animation effects and
2. Transition effects

Animation refers to special sound and visual effects that can be added to text or other objects to make them appear as dynamic rather than static images. Transition on the other hand refers to special effects that can be added on the entrance of a slide during a slide show. Each slide can have only a single transition effect but multiple animation effects as each object on the slide can have different effects.

1. The Slide view can be used to insert and test the Animation effects
2. The Slide view  and the Slide Sorter View can be used to insert and test the Transition effects.
