9.1 Is Bluetooth a suitable technology to use in this scenario? Motivate your answer - NSC Computer Application Technology - Question 9 - 2017 - Paper 2

1. Ensure that the device is paired with the server. If it isn’t, it won’t be able to connect.
2. Restart the device and server to refresh the connection and eliminate any temporary glitches.

Streaming refers to the continuous transmission of audio or video content over the internet. In streaming, the data is delivered in small packets, allowing the content to be played back in real-time as it is received, rather than waiting for the entire file to download.

1. A high bandwidth internet connection to support the data flow required for streaming.
2. A digital camera or computer capable of capturing the event and transmitting it live.

One potential disadvantage of live streaming is that data usage can be high, which may lead to buffering issues if the connection speed is insufficient.

Speech-to-text software can be used by visually impaired users to input data and navigate their devices through voice commands.

1. Wireless networks are generally more convenient as they eliminate the need for physical cables, allowing devices to connect from anywhere within range.
2. Wireless networks facilitate mobility, enabling users to move freely with their devices without being restricted by cable length.

1. A wireless access point or wireless router to enable network connectivity.
2. A Wi-Fi adapter to provide wireless capability to devices that do not have built-in wireless functionality.

Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax) would be suitable for creating a fast and reliable wireless network.

1. NFC can be used for contactless payments, allowing users to make transactions by tapping their devices at a point of sale.
2. NFC can be used for data sharing, enabling quick transfer of files or information between two devices that are within close proximity.

1. Installing up-to-date antivirus software to protect against malicious programs that can compromise system security.
2. Regularly scanning the computer for vulnerabilities and suspicious attachments in emails to avoid threats from unauthorized access.

A driver functions as a translator between the operating system and the hardware of a device, enabling the system to communicate effectively with hardware components and ensuring proper operation.

Utilizing electronic clickers for vote counting is faster than manual counting. It allows for a more accurate and efficient counting process while reducing human errors during the tallying phase.

Large amounts of voting data can be securely stored on digital mediums such as servers, rather than relying on physical copies like paper, which reduces the risk of loss and enhances accessibility for future reference.
