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. Rapid Tracking: RFID tags can be read quickly without direct line-of-sight, allowing fast inventory management and asset tracking.
2. Enhanced Data Storage: RFID tags can store more information than traditional barcode labels, providing additional data about the hardware item.

A network administrator is crucial for managing, monitoring, and maintaining the network infrastructure. This role ensures network security, optimizes performance, and troubleshoots issues that may arise, ensuring minimal downtime and efficient operation.

1. Use of Special Characters: Passwords should include special characters (e.g., @, #, $, %) to increase complexity.
2. Minimum Length: Passwords should be at least 12 characters long to enhance security against brute force attacks.

1. VPN (Virtual Private Network): This technology creates a secure tunnel over the Internet, allowing remote users to access the organization's network as if they were directly connected.
2. Remote Desktop Protocol (RDP): RDP allows a user to take control of a remote computer over the network, enabling them to perform tasks as if they were physically present at that machine.

The administrator can safeguard computers by:

1. Installing Anti-virus Software: Ensure that reliable anti-virus software is installed and kept up-to-date to detect and remove malicious software.
2. Regular Updates: Keeping the operating system and all software updated minimizes vulnerabilities that can be exploited.

1. User Management: Allocating and managing user access rights to ensure security and privacy.
2. Monitoring Network Performance: Regularly reviewing network performance to identify and resolve issues, ensuring optimal operation.

Spam e-mail refers to unsolicited messages sent in bulk, usually with commercial intent, aiming to promote products or services. They may also contain malicious links or attachments.

1. Use Strong Passwords and Two-Factor Authentication: Implementing strong, unique passwords and enabling two-factor authentication adds an extra layer of security.
2. Be Wary of Sharing Personal Information: Users should refrain from sharing sensitive personal information on social media or public forums.

Skype employs end-to-end encryption to secure calls, meaning that only the communicating users can access the content of the call, protecting it from interception.

The purpose of a digital certificate is to authenticate the identity of a website or user and establish secure communications by using encryption to protect data exchanged online.

1. Check the Author's Credentials: Verify the qualifications and background of the author to ensure expertise in the subject matter.
2. Look for Reliable Sources: Cross-reference information with reputable sources or peer-reviewed journals to confirm accuracy.

The Internet of Things (IoT) refers to a network of interconnected devices that communicate and exchange data over the Internet. These devices range from household appliances to industrial machinery, all contributing to enhanced automation and efficiency.

1. Adjust Display Settings: Lowering the screen brightness and setting shorter screen timeout durations can conserve battery life.
2. Turn Off Unused Features: Disabling GPS, Bluetooth, and Wi-Fi when not in use can significantly extend battery life.

A rootkit is a collection of software tools that allow unauthorized users to gain control of a computer system without being detected. Rootkits hide their presence by integrating with the operating system and can be used for malicious purposes, such as stealing sensitive data.

BitTorrent is supported by a peer-to-peer (P2P) network, which allows users to share files directly with one another instead of relying on a single server for distribution.

One disadvantage is that users may inadvertently download illegal content, leading to potential legal consequences.

Using a file-sharing service removes the size limitations and potential issues of e-mail attachments, allowing for more extensive collaboration on documents in real-time while ensuring that all collaborators have access to the most recent version.

1. Automatic Backup: Files are backed up automatically in the cloud, preventing data loss.
2. Collaboration: Multiple users can work on files simultaneously, increasing efficiency.
3. Access from Anywhere: Users can access files from any device with Internet connectivity.

1. User Interface (UI) Design: Ensure that the app is intuitive and user-friendly to enhance the user experience.
2. Performance Optimization: Optimize speed and responsiveness to cater to users with varying device capabilities.
3. Compatibility: Consider features that work across different devices, operating systems, and screen sizes.
