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 or harmful materials, which can leach into the soil and water supply, posing serious risks to both human health and the environment.

1. Keep old devices or replace them only when necessary.
2. Donate or sell electronics that are still in working condition to extend their life cycle.

Before recycling or discarding any electronic storage device, users should format or clear the device to permanently erase personal data. This ensures that sensitive information cannot be accessed or retrieved by others.

The employees typically use e-mail as a primary method of communication due to its effectiveness in sending messages and documents.

With POP, your emails are downloaded to your device and deleted from the server, limiting access to that device. In contrast, IMAP allows emails to remain on the server and be accessed from multiple devices, enabling better synchronization.

Spam clogs the Internet with unnecessary traffic, making it difficult for employees to find important messages. It can also expose employees to phishing attempts and other security risks.

To identify fake news, one can: 1. Check the references of the author involved. 2. Apply common sense to assess the credibility of the information.

The file should be uploaded to cloud storage/service and then shared, using platforms like Google Drive or WeTransfer.

One risk is that the service may not have good security practices, which could lead to sensitive information being exposed.

A media repository is an online storage location that facilitates the sharing, downloading, and streaming of files, allowing users to access content from anywhere at any time.

Ubiquity refers to the ability to access files and data from any location and device, providing seamless interaction with digital information across different platforms.

A RAT, or Remote Access Trojan, is a type of malware that allows an attacker to gain unauthorized access to a user's computer, often without their knowledge.

1. Downloading or opening an infected attachment in an email. 2. Downloading/installing software from malicious sources.

1. To steal users' personal information for identity theft.
2. To redirect website traffic to phishing or malicious sites.

A distributed database is a database that is spread/stored across multiple servers located in different geographical areas, allowing for improved accessibility and reliability.

With Duplication, every separate site retains a complete copy of the entire database. In Partitioning, each site stores only the data relevant to them, which helps to minimize redundancy.

Regular data synchronization is necessary to ensure that all sites maintain consistency and up-to-date copies of data, preventing discrepancies that could compromise data integrity.

Such a system is called a Decision Support System (DSS), which enhances decision-making through the analysis of data.

An expert system can create a rule-based framework that processes data from the DSS, allowing for quicker responses and recommendations based on predefined rules and historical data.

Open-source refers to software for which the source code is freely available, allowing users to modify and adapt the software to suit their needs.

Temporary or redundant files, which are often unnecessary and can be deleted to free up space.

The digital divide refers to the gap between individuals who have easy access to computers and the internet and those who do not.

1. Lack of financial resources to acquire technology.
2. Differences in educational levels which affect an individual's ability to use technology.

Hyper-automation goes beyond RPA by incorporating additional technologies such as AI and machine learning to automate more complex tasks and processes.

RPA can assist in automating repetitive tasks, allowing businesses to maintain productivity even with a shrinking labor force due to an aging population, thus ensuring operational efficiency in factories.

Virtual reality immerses users in a completely digital environment, while augmented reality overlays digital information onto the real world, enhancing the user's perception of their environment.

One could enhance existing realities by integrating more interactive elements that allow users to engage with the digital components in real-time and enhance their overall experience.
