12. a) List THREE advantages a company is likely to attain from the use of emails.

• Speed: Emails are delivered almost instantly, enabling rapid communication.
• Cost-effectiveness: Sending emails is generally cheaper than traditional mail or phone calls, especially for long distances.
• Record-keeping: Emails provide a written record of communication that can be easily stored, searched, and retrieved.

12. b) List THREE reasons for choosing Microsoft Office PowerPoint for a presentation.

• Visual appeal: PowerPoint allows for the creation of visually engaging slides with text, images, videos, and animations.
• Ease of use: It provides user-friendly tools and templates that simplify the process of designing and organizing content.
• Audience engagement: Features like transitions, animations, and presenter tools help to maintain audience interest and deliver information effectively.

13. Differentiate between absolute and relative cell referencing as used in Microsoft Office Excel.

• Relative cell referencing refers to a cell's position relative to the cell containing the formula. When a formula with relative references is copied to another cell, the references automatically adjust. For example, if cell A1 contains the formula $=B1+C1$ and is copied to A2, the formula in A2 becomes $=B2+C2$.
• Absolute cell referencing refers to a specific cell that does not change when the formula is copied to other cells. This is achieved by adding dollar signs ($) before the column letter and row number. For example, if cell A1 contains the formula `=$B$1+$C$1` and is copied to A2, the formula in A2 remains `=$B$1+$C$1`.

• c) Save document: The function of saving a document is to store the current state of the document on a storage device (like a hard drive or cloud) so that it can be opened and accessed again later.
• d) Spell checker: The function of a spell checker is to identify and highlight misspelled words in a document, often suggesting corrections, to help ensure accuracy and professionalism.
