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

• Safer work environment: Automation reduces the risk of human error and workplace injuries.
• Greater precision and consistency: Technology ensures that assembly processes are more precise, resulting in higher quality products.

A learning algorithm observes current manufacturing processes and sales data to identify trends. By analyzing which vehicle features are most popular, it can create customized recommendations and optimize production schedules. This leads to better alignment between production and market demand.

RFID stands for Radio Frequency Identification.

Passive RFID tags operate without a battery. They receive power from the reader's radio signal when it is close enough. This energy activates the tag, allowing it to transmit its stored data to the reader for processing toll fees.

The technology used to determine the location of a vehicle is GPS (Global Positioning System).

Active tags are required for satellite tracking because they have their own power source, enabling them to communicate over longer distances and with greater accuracy than passive tags.

Uncapped means that there is no limit on the amount of data that can be used in a month. Users can utilize the service as much as they want without incurring additional charges based on data usage.

Fibre connections typically offer higher speeds and more reliable service compared to mobile LTE. This is particularly beneficial for households that require a stable internet connection for multiple users and devices.

A router is required to connect to the FTTH service and distribute internet connectivity to various devices within the home.

The '70GB Night Surfer Data' can be beneficial if the company operates during off-peak hours, allowing for data-intensive activities at a lower cost. However, if the company primarily operates during the day, this package may not offer significant advantages.

A rootkit is a type of software designed to obtain administrator rights to a computer, allowing unauthorized access and control.

One implication of a rootkit is that it can open the computer for hacking or illegally accessing data, often without the user's awareness.

Social engineering entails manipulating individuals into divulging confidential or personal information that may be used for fraudulent purposes. This often involves psychological tactics to build trust and deceive the target.

Antivirus software identifies malware by scanning files for known patterns or signatures and behavior that matches malware activities. It also detects anomalies in system behavior that may indicate an infection.

• Finding possible connections: AI can analyze large datasets to discover hidden patterns and relationships.
• Identifying potential threats: AI can monitor systems for unusual behaviors and predict security risks.

In the duplication model, each separate site has a complete copy of the data, while in the partitioning model, each site stores only part of the database, allowing more efficient data management.

Purging data involves deleting or removing records from a database permanently to free up space and maintain performance.

Records need to be purged to limit the size of the database file, improve database performance, and ensure that only relevant, accurate information is retained.

Virtualisation is the creation of a virtual version of a computing resource, such as a server or operating system, allowing multiple virtual instances to run on a single physical hardware base.

One benefit of virtualisation for the user is the convenience of not having to keep multiple devices, as various applications can run on a single server environment.

Yes, the user must pay for the proprietary operating system to avoid committing piracy, unless a free version or license is provided by the vendor.

• Combining multiple machines: Virtualisation allows resources from different machines to be pooled together into one powerful service, enhancing performance.
• Resource sharing: It enables the sharing of resources within a powerful machine across multiple users, allowing efficient use of hardware.

Frequent password changes are important for security reasons to minimize the risk of unauthorized access and to protect against potential data breaches.

• Too short: The password 'mfundi' is less than the recommended length of 8 characters.
• Lacks complexity: It does not include special characters or a mixture of uppercase and lowercase letters.

Quantum computing can analyze vast amounts of data at unprecedented speeds, allowing for better monitoring and modeling of virus spread patterns.

• Latency issues: Edge computing reduces the latency that occurs when data needs to be sent to a centralized cloud server before processing.
• Data sovereignty: It allows sensitive data to be processed locally, addressing concerns about data privacy and compliance with regulations.
