Mr Jones, who is one of the teachers at the school, started a video-editing club at the school - NSC Information Technology - Question 6 - 2024 - Paper 2

Cores are processing units that enable a computer to perform multiple tasks simultaneously. Each core can process its own thread, improving the overall processing capability.

A thread is the smallest unit of processing that can be scheduled by an operating system. It is a sequence of programmed instructions that can be managed independently by the scheduler.

The best processing technique would be multiprocessing. This approach allows multiple threads from different programs to run simultaneously across the eight cores, significantly reducing processing time and improving performance.

GPUs are designed to handle graphics processing tasks more efficiently than CPUs. They can execute thousands of threads in parallel, making them ideal for tasks that require intensive calculations, such as video editing and rendering.

1. Flexibility: Virtual machines allow the members to test software in different operating environments without needing separate hardware.
2. Saves time: They help in quickly setting up the environment needed for software testing, thereby reducing delays.
3. Cost-effective: Virtual machines minimize hardware costs as multiple instances can run on a single physical machine.

Virtual memory is a memory management capability that creates an illusion of a larger memory pool by using hard drive space. When the physical RAM is insufficient, the system uses a portion of the hard drive as additional memory, which can slow down performance. To solve excessive virtual memory usage, increasing the physical RAM in the computers is recommended.

SaaS, or Software as a Service, is a software distribution model in which applications are hosted in the cloud and made accessible to users over the internet. Users typically pay a subscription fee to utilize the software.

1. Cost Saving: The club doesn’t need to purchase expensive software upfront, but rather pays a monthly fee.
2. Accessibility: Club members can access the software from anywhere, making collaboration easier.
3. Automatic Updates: Users always have the latest software version without manual updates.

A reliable and fast internet connection is essential for accessing and using SaaS applications effectively.

Streaming allows users to watch videos instantly without the need to download them first.

1. Accuracy: Check if the information is consistent with other credible sources.
2. Currency: Ensure the information is up-to-date and relevant to the current context.

Intellectual property refers to creations of the mind, such as inventions, literary and artistic works, and designs, which are legally protected from unauthorized use.

1. He does not have permission to share the work of somebody else, which could lead to copyright infringement.
2. He needs to give credit to the original creators, respecting their rights and ensuring proper acknowledgment.

A webinar is an online seminar or workshop that allows participants to engage in discussions or presentations via the internet.

Participants can attend webinars without having to travel, making them more accessible.

Different compression techniques include lossy and lossless compression.
Lossy compression reduces file size by removing less critical data while lossless compression retains all data.
For the club's needs, lossless compression should be used to maintain video quality while keeping file sizes manageable.
