A company named e-Waste Technologies Africa specialises in the recycling of electronic waste - NSC Information Technology - Question 6 - 2022 - Paper 2

Electronic waste often contains toxic and harmful materials, such as lead and mercury, which can leach into the soil and water supply if not disposed of properly, leading to environmental contamination.

1. Keep old devices for replacement only when necessary and extend their lifecycle by maintaining them well.
2. Donate or sell old electronics instead of disposing them in landfill.

Before recycling or destroying any electronic storage device, users should format or clear all data to ensure that personal information cannot be accessed or retrieved by unauthorized individuals.

The employees communicate using e-mail as their primary method for daily communication, enabling them to exchange information swiftly.

With POP (Post Office Protocol), emails are downloaded to your device and typically deleted from the server, while IMAP (Internet Message Access Protocol) allows emails to remain on the server and be accessed from multiple devices.

Spam clogs the internet and creates unnecessary traffic, which can affect productivity and may expose employees to malicious content.

1. Check the sources referenced to validate the information.
2. Apply common sense to evaluate the credibility of the news.

The file should be uploaded to a cloud storage service, such as Google Drive or Dropbox, and then shared from there.

One risk of sending the attachment via cloud storage is that the service might not have good security practices, potentially exposing sensitive information.

A media repository is an online storage solution where files can be shared, stored, and accessed digitally, often used for managing and distributing digital content.

Ubiquity refers to the ability to access and work with files from any location at any time on the internet, facilitating seamless collaboration regardless of geographical constraints.

A RAT, or Remote Access Trojan, is a type of malware that allows a remote attacker to control a computer or network, potentially leading to data theft or system compromises.

1. By downloading and opening infected attachments in emails.
2. By downloading software from untrusted or malicious websites.

1. To steal users' personal information, such as email addresses or credit card numbers, for identity theft.
2. To redirect traffic to phishing sites to gain sensitive information deceitfully.

A distributed database is a database that is spread or stored across multiple locations, allowing for greater accessibility and redundancy in data management.

Duplication means that every site has a complete copy of the database, while Partitioning means that each site manages its own data without a full copy, both offering different levels of efficiency and synchronization.

Regular data synchronization is crucial to maintain data integrity and consistency across all sites, ensuring that all copies of the database remain updated and reliable.

The system used for gathering and analyzing information is commonly referred to as a Decision Support System (DSS).

An expert system can enhance the decision-making process by providing rules and guidelines that facilitate rapid analysis and recommendations based on the data processed by the DSS.

Open-source refers to software that is made available with its source code, allowing users to modify and adapt it according to their needs.

Temporary files are one type of file that the disk clean-up program will identify and remove to free up storage space.

The digital divide refers to the gap between individuals who have access to computers and the internet and those who do not, often resulting in disparities in information access and technology utilization.

1. Lack of financial resources to acquire technology.
2. Differences in educational levels regarding technology literacy.

Hyper-automation involves the integration of advanced technologies, including AI, to automate complex business processes, while RPA (Robotic Process Automation) focuses on automating repetitive, rule-based tasks using software robots.

RPA can address the aging population issue in factories by automating routine tasks, thus maintaining productivity levels without the need for human labor where skills may be lacking.

Virtual reality immerses the user in a completely digital environment, while augmented reality overlays digital information onto the real world, enhancing user interaction with their actual surroundings.

The further advancement of augmented reality can enhance training and educational opportunities by providing interactive experiences that blend digital content with real-world settings, facilitating better engagement and understanding.
