An ICT system must be implemented for a national television station running a talent show - NSC Information Technology - Question 2 - 2023 - Paper 2

The term 'multicore' refers to a processor that contains more than one processing unit or core on a single chip. This design allows for parallel processing, enabling multiple tasks or threads to be executed simultaneously, which enhances performance and efficiency.

One processing technique that allows for full utilization of multicore technology is 'multi-threading.' This technique enables a single process to be broken down into multiple threads that can run concurrently on different cores.

Multicore technology improves processor performance by allowing multiple tasks to be processed simultaneously due to the presence of multiple cores. This reduces the time taken to complete tasks, as they can be handled in parallel rather than sequentially.

Including a graphics processor (GPU) enhances the performance of the laptop as it handles the processing of graphical images and rendering. This offloads the CPU, allowing it to handle other tasks more efficiently and ultimately improving overall system performance.

The size of a screen is typically measured diagonally from one corner of the screen to the opposite corner. This measurement is usually expressed in inches.

The HDMI connector is preferred in modern devices because it supports higher resolution video and audio transmission in one cable, enabling better quality of visual and audio output compared to VGA, which is limited to video transmission only.

The use of flash technology in SSDs is advantageous because it offers high access speeds and higher read/write speeds, greatly enhancing system responsiveness and performance. Additionally, SSDs produce no noise and consume less power, making them more efficient.

Wi-Fi is better suited for wireless connections due to its higher bandwidth and speed, allowing for faster data transmission over greater distances. It supports a larger number of devices, making it more suitable for network environments like talent shows than Bluetooth, which has a more limited range and capacity.

An operating system is system software that manages the hardware and software resources of a computer, controls the execution of programs, and provides a user interface for interaction with the computer.

I would recommend open-source software because it allows for greater flexibility and customizability as the source code is accessible for further development. Additionally, it often comes with community support and regular updates, contributing to a more secure and up-to-date software environment.

The SaaS model entails that software is not bought outright but is rented on a subscription basis. Users access the software over the internet or cloud, allowing for easier updates and maintenance.

The SaaS model is preferred as it eases the rollout of updates and fixes, reduces the need for extensive customer support, and enhances software accessibility. It provides recurring revenue for companies, allowing for better financial stability and allowing developers to focus on delivering value and new features.

Antivirus software can contribute to decreased performance by continuously scanning files for viruses and executing background tasks that consume system resources. This can lead to slower response times and reduced efficiency, particularly in systems with limited processing power.
