Step 1
9.1.1 Name TWO features, other than the resolution, that you will consider when buying a data projector.
Answer
When buying a data projector, I would consider the following features:
- Brightness (measured in lumens): A brighter projector can be used in well-lit environments, making it suitable for presentations in a school hall.
- Portability: It is essential to know how easy it is to transport the projector to different locations, especially for a school event.
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 because playing standard video files does not require intensive graphic processing. The built-in graphics capabilities of modern notebook computers are sufficient for handling video playback, which is less demanding than tasks such as gaming or 3D rendering.

9.3.2 Explain how bandwidth influences the streaming of movies.
Answer
Bandwidth significantly influences streaming as it determines the amount of data that can be transmitted at any given time. Higher bandwidth allows for quicker data transfer, leading to smoother playback with fewer interruptions. Conversely, lower bandwidth may result in buffering and reduced video quality.
Step 6
9.3.3 Discuss TWO limitations of using a 4G cellular connection to stream a movie.
Answer
Two limitations of using a 4G cellular connection to stream a movie are:
- Data Caps: Many cellular plans have limits on data usage, and streaming movies can consume large amounts of data quickly, potentially leading to additional charges.
- Signal Reliability: 4G connections can experience fluctuations in signal strength, which might cause interruptions during streaming or affect the quality and continuity of the movie.
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 infections: To prevent this, it is crucial to install antivirus software and keep it updated.
- Unauthorized access/Hacking: Using a strong password and activating the firewall can prevent unauthorized access.
