Explanation:

• Question 10: Presentation software is designed to combine visuals, text, and multimedia for clear and persuasive information presentation. The other options are related to database management, computer performance optimization, and file recovery, which are not the main role of presentation software.
• Question 11: Sir Tim Berners - Lee is credited with developing HTML (Hyper - Text Markup Language) and HTTP (Hyper - Text Transfer Protocol), which are fundamental for the World Wide Web. TCP/IP was developed by Vinton Cerf and others. The MAC address was not developed by him. URL standards are related to web addressing but not his main development.
• Question 12: SaaS (Software as a Service) stores data on remote servers, so there is no heavy dependency on local storage. It is designed to be scalable. Compatibility is usually not a major issue as it is accessed via a web browser. However, security and privacy concerns (e.g., data breaches on the provider's side) are a known disadvantage.

Answer:

1. It enables users to combine visuals, text, and multimedia to present information clearly and persuasively.
2. HTML and HTTP
3. Security and privacy concerns
