Step 1
9.1.1 Name TWO features, other than the resolution, that you will consider when buying a data projector.
Answer
When selecting a data projector, two important features to consider are:
-
Brightness (Lumens): This determines how well the projector can display images in various lighting conditions. A higher brightness rating is preferable for clear images in well-lit environments.
-
Connection Options/Compatibility: Assessing the connectivity options is essential to ensure compatibility with the notebook computer and other devices. This includes checking for HDMI, VGA, or wireless connections.
Step 2
9.1.2 Explain why it will NOT be necessary for the notebook computer to have a dedicated graphics card for showing movies.
Answer
A dedicated graphics card is not necessary for showing movies on the notebook because movie playback is not graphically intensive. The built-in graphics of most modern notebooks are sufficient to handle video playback without the need for a dedicated graphics card.
Step 3
9.2 Give ONE reason why you do NOT have to use a mouse with a notebook computer.
Answer
You do not need to use a mouse with a notebook computer because most notebooks come with a built-in touchpad, which allows for easy navigation and control without the need for an external pointing device.

Step 5
9.3.2 Explain how bandwidth influences the streaming of movies.
Answer
Bandwidth significantly influences streaming by determining how much data can be transferred at a time. Higher bandwidth allows for a smoother, uninterrupted viewing experience with higher resolution, while lower bandwidth may lead to buffering or reduced video quality.
Step 6
9.3.3 Discuss TWO limitations of using a 4G cellular connection to stream a movie.
Answer
Using a 4G cellular connection for streaming has two main limitations:
-
Data Limits: Streaming movies can consume a large amount of data, leading to potential overage charges if the data cap is exceeded.
-
Signal Quality: 4G connections can experience fluctuations in signal strength, which may cause interruptions, buffering, or degraded video quality during streaming.
Step 7
9.4 Identify TWO risks that your notebook computer could be exposed to by being connected to the internet AND suggest a way to prevent harm from EACH risk that you identify.
Answer
Two risks include:
-
Malware: Malware can compromise the notebook's security. To prevent this, you should install antivirus software and keep it updated regularly.
-
Unauthorized Access (Hacking): This can result from weak passwords. To mitigate this risk, use strong, complex passwords and enable a firewall.
Step 8
9.5.1 What steps must you take before creating a Table of Contents that can be added to a word processing document?
Answer
Before creating a Table of Contents, you should apply appropriate styles to the headings in your document. This enables the word processor to recognize the structure and generate the Table of Contents correctly.

-
Time Efficiency: Mail merge allows for the quick generation of personalised emails for multiple recipients without needing to type out each message individually.
-
Personalisation: It enables the insertion of individual names and information into the messages, making them more engaging and relevant to each recipient.
