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. Tracking Capability: RFID tags allow for efficient tracking of items, helping to manage inventory and monitor the location of hardware within the café.
2. Speed of Scanning: RFID tags can be read quickly even when multiple items are tagged, reducing the time needed for inventory checks and facilitating smoother operations.

A network administrator is essential for maintaining the network’s health and security. They ensure all devices are connected properly, monitor the traffic to prevent bottlenecks, and safeguard the network against external threats, ensuring a reliable environment for users.

1. Use of Special Characters: Passwords should include special characters (e.g., !, @, #) to increase complexity and resistance against guessing attacks.
2. Length Requirement: Passwords should be a minimum of 8-12 characters to make them less susceptible to brute-force attacks.

1. Remote Desktop: This technology allows users to connect to a remote server and view its desktop as if they were sitting right in front of it, enabling control over the server’s applications and files.
2. VPN (Virtual Private Network): A VPN creates a secure connection over the Internet to a remote server, allowing users to access resources as if they were directly connected to the local network.

To safeguard against virus attacks, the administrator should regularly update anti-virus software and ensure that a firewall is installed and properly configured to monitor and control incoming and outgoing network traffic.

1. User Management: The administrator should allocate and manage user rights, including the ability to add or remove users from the network.
2. Backup Management: Regular backups of data should be performed to protect against data loss due to hardware failures or other incidents.

Spam e-mail refers to unsolicited messages sent in bulk, usually with the intention of promoting products or services. These emails often attempt to deceive the recipient into purchasing or engaging with the content.

1. Use Strong Passwords: Users should employ complex passwords that are not easily guessed and change them periodically.
2. Be Cautious of Personal Information: Avoid sharing personal details online and be cautious of phishing attempts that seek to obtain sensitive information.

Skype uses end-to-end encryption, ensuring that only the communicating users can read the messages or listen to the calls, helping to protect the content of the communications from potential intruders.

A digital certificate is used to authenticate the identity of a website or organization, establishing a secure link between the user and the entity, thereby ensuring that the information exchanged is protected.

1. Check for Site Credibility: Users should verify the reputation of the website by cross-referencing with established and reputable sources.
2. Review Author Information: Look for information regarding the author or organization behind the content to ensure that they are credible and knowledgeable in the field.

The Internet of Things (IoT) is a concept where everyday objects are embedded with sensors and connectivity capabilities, allowing them to send and receive data over the Internet, enabling smarter operations and automation.

1. Adjust Display Settings: Lowering the screen brightness and reducing the display timeout can significantly conserve battery power.
2. Disable Unused Features: Switching off GPS, Bluetooth, or Wi-Fi when not in use can greatly enhance battery longevity.

A rootkit is a collection of software tools that enable unauthorized access to a computer while concealing its existence. Typically used for malicious purposes, rootkits can manipulate the operating system to remain hidden and establish backdoor access for cybercriminals.

BitTorrent is supported by a peer-to-peer (P2P) network, allowing users to share files directly between their devices without the need for a central server, enhancing download speeds and data distribution.

Another disadvantage of using BitTorrent is that it may expose users to legal risks, as sharing copyrighted materials without permission can lead to potential lawsuits.

Using a file-sharing service allows for larger files to be shared without size limitations imposed by email providers. It also enables real-time collaboration on documents, making it easier for teams to work together.

1. Automatic Backups: Changes made to files are automatically synchronized to the cloud, ensuring that the latest versions are always available.
2. Accessibility Across Devices: Users can access their files from any device with internet connectivity, providing flexibility.
3. Version Control: Users can maintain access to previous versions of their files, allowing for recovery in case of accidental deletion or corruption.

1. User Interface (UI) Design: The interface should be intuitive and responsive, ensuring ease of use on smaller screens.
2. Performance Optimization: Apps must be optimized for various device specifications to ensure smooth operation, even on lower-end devices.
3. Data Consumption: Consideration should be given to how much data the app consumes so users can have control over their data plans.
