A large transport company wants to incorporate information communication technology in their many areas of business in light of the 4th industrial revolution - NSC Information Technology - Question 6 - 2022 - Paper 2

1. Safer work environment: Automation reduces the risk of human error and accidents on the production line, making it a safer place for workers.
2. Increased productivity: Automated systems can operate continuously and consistently, leading to faster production times and higher output.

A learning algorithm can observe the current manufacturing processes and identify patterns in vehicle production, such as which models are most popular. By analyzing historical data, the algorithm can create a set of rules that streamline production methods, optimizing overall efficiency and inventory management, ultimately improving sales performance.

RFID stands for Radio Frequency Identification.

Passive RFID tags do not have their own power source. Instead, they harness energy from the reader's radio signal to transmit data. When the tag is within range of the reader, it reflects back its unique identification number, which is used to process the toll fee.

The technology used is GPS (Global Positioning System).

Active tags are required for satellite tracking because they have their own power source, which enables them to transmit data over greater distances continuously and provide more accurate location tracking compared to passive tags.

Being uncapped means there is no limit to the amount of data that can be used in a month; users can consume as much data as they need without incurring additional fees.

Fibre offers faster and more reliable internet connectivity compared to mobile LTE, making it ideal for households that rely heavily on internet usage, such as for streaming or remote work.

You would need a router or ONT (Optical Network Terminal) to connect to the FTTH service.

The 70GB Night Surfer Data could benefit the company if it allows for cost-effective data usage during off-peak hours, enabling more efficient data consumption without incurring additional charges, particularly for tasks that require large amounts of data.

A rootkit is a form of malware designed to allow unauthorized access to a computer or network while hiding its presence. It can manipulate system processes and files to maintain control over the infected system.

One implication is that it can allow attackers to gain administrative privileges on the system, leading to potential data breaches or unauthorized access to sensitive employee information.

Social engineering involves manipulating individuals into divulging confidential information by exploiting human psychology rather than technical hacking techniques.

Antivirus software identifies malware by scanning files for known virus signatures, behavioral patterns, and unusual activities that may indicate malicious intent.

1. Data analysis: AI algorithms can analyze large datasets to find trends or anomalies that would be difficult for humans to detect.
2. Predictive modeling: AI can create models to predict future events or customer behavior based on historical data.

In the duplication model, each branch stores a complete copy of the entire database, making it easier to access all information locally. In contrast, the partitioning model divides the database into segments, where each branch only stores the portion relevant to its operations, which helps in optimizing storage and processing efficiency.

Purging data involves deleting or removing outdated or unnecessary records from the database to free up space and maintain data integrity.

Records need to be purged to limit the size of the database, enhance performance, and ensure compliance with data privacy regulations.

Virtualisation is the process of creating virtual versions of physical computing resources, allowing multiple operating systems and applications to run on a single physical machine.

One benefit is the convenience of managing multiple applications on a single device, which reduces hardware costs and simplifies updates.

Yes, the company must pay for the proprietary operating system to avoid committing piracy, as using it without a license violates copyright laws.

Frequent password changes enhance security by reducing the risk of unauthorized access due to compromised passwords or password leaks.

1. Password too short: The password 'mfundi' does not meet the recommended length, which should be more than 8 characters.
2. Lacks complexity: It only uses lowercase letters and does not include uppercase letters, numbers, or special characters.

Quantum computing can be utilized to quickly analyze and process large datasets related to virus interactions, enabling researchers to understand infection patterns and model the spread more accurately.

1. Latency issues: Edge computing reduces latency by processing data closer to the source rather than relying on distant servers.
2. Bandwidth limitations: It minimizes the amount of data sent to the cloud, thus alleviating bandwidth strain and improving overall system performance.
