The IT learners are going to run an Internet café from the local community centre where they have been allocated one room - NSC Information Technology - Question 6 - 2016 - Paper 2

1. Item can be tracked: RFID tags allow the precise tracking of items, which aids in inventory management.
2. No need for line of sight for scanning: Unlike barcodes, RFID tags can be read without being directly in front of the scanner, making the process faster and more efficient.

A network administrator is essential for managing network resources, ensuring security and reliability, and troubleshooting issues that arise. This role is critical for maintaining the operational integrity of the network, which supports all users in the Internet café.

1. Include special characters: This adds complexity to the password and makes it harder to guess.
2. Use both uppercase and lowercase letters: Mixing letter cases enhances password security by increasing the number of possible combinations.

1. Remote Desktop Protocol (RDP): This allows a user to connect to another computer over the network, providing full access to the interface as if they were sitting in front of it.
2. Virtual Private Network (VPN): This creates a secure encrypted connection to another network over the Internet, allowing users to access resources securely as though they were on the same local network.

1. Install antivirus software: Regularly updating and running antivirus software can help detect and remove malware before it causes harm.
2. Keep the operating system and applications up to date: Regular updates help patch vulnerabilities that could be exploited by viruses.

1. Allocating user rights: The administrator manages user accounts and defines permissions to protect sensitive data.
2. Backing up data: Regular backups ensure that data can be restored in case of a loss due to an attack or hardware failure.

Spam e-mail refers to unsolicited and irrelevant messages sent in bulk to many recipients, usually for advertising purposes. It can clutter inboxes and may contain harmful links.

1. Use strong passwords and change them regularly: This helps protect personal accounts from unauthorized access.
2. Monitor financial statements regularly: Keeping an eye on statements helps detect any unauthorized transactions quickly.

Skype uses end-to-end encryption to secure calls, ensuring that only the communicating users can access the content of the conversation.

A digital certificate is used to authenticate the identity of a website or individual, establishing trust in online communications by confirming that the information being exchanged is legitimate.

1. Check the website’s security: Users should ensure the site has HTTPS and is reputable.
2. Evaluate the author’s credibility: Researching the author’s background can help verify the reliability of the information presented.

The Internet of Things (IoT) refers to the interconnection of everyday devices to the Internet, allowing them to send and receive data. This connectivity enables proactive monitoring and control, enhancing user experiences and operational efficiency.

1. Change the display settings to dim: Reducing brightness can significantly conserve battery life.
2. Switch off Wi-Fi and Bluetooth when not in use: Disabling these features helps to save power by preventing the device from constantly searching for connections.

A rootkit is a collection of tools designed to gain unauthorized access to a computer system while hiding its existence. They can allow an attacker to maintain privileged access over the system, often without the user's knowledge.

BitTorrent operates on a peer-to-peer protocol, allowing users to share files directly with each other without relying on a central server.

One disadvantage of using BitTorrent is that the IP address of the user is exposed, which can lead to potential legal issues or privacy concerns.

Using a file-sharing service allows for larger file transfers, real-time collaboration, and ensures that all users are accessing the latest version of the document, reducing confusion and potential errors.

1. Automatic file backups: Changes are automatically saved to the cloud, protecting against data loss.
2. Accessibility from multiple devices: Users can access their files from any device connected to the internet.
3. Version control: Users can keep track of file changes and revert to prior versions if needed.

1. User interface design: The interface should be intuitive and easy to navigate on smaller screens.
2. Battery consumption: Apps should be optimized to minimize battery usage and extend device life.
3. Internet data management: The app should manage data effectively, ensuring minimal usage to prevent extra costs for users.
