Example 1: Simple Question
Q: What are the advantages and disadvantages of artificial intelligence in healthcare? Provide examples.
A: Artificial intelligence (AI) has several advantages in healthcare. It can analyze large amounts of medical data quickly and accurately, leading to faster and more accurate diagnoses. AI-powered chatbots can provide 24/7 patient support, reducing the burden on healthcare professionals. Moreover, AI algorithms can predict disease outbreaks and help in resource allocation for effective public health management.
However, there are also disadvantages to the use of AI in healthcare. One major concern is the potential for biases in AI algorithms, which can lead to discriminatory healthcare practices. Additionally, there are ethical considerations regarding the privacy and security of patient data when using AI systems. It is crucial to strike a balance between the benefits and risks of AI in healthcare to ensure responsible and equitable use of this technology.
Example 2: Medium Question
Q: Explain the concept of smart contracts in blockchain technology with a real-life scenario.
A: Smart contracts are self-executing contracts with the terms of the agreement written into code. These contracts are stored on a blockchain, ensuring transparency and immutability. A real-life scenario that exemplifies the concept of smart contracts is the sale of digital artwork.
Suppose an artist wants to sell their artwork online. They can create a smart contract that automatically transfers ownership of the artwork to the buyer once the payment is received. The terms of the contract, including the price and conditions, are coded into the smart contract. Once the conditions are met, such as the buyer sending the payment, the ownership of the artwork is transferred to the buyer automatically, eliminating the need for intermediaries like galleries or auction houses.
Smart contracts in blockchain technology provide efficiency, transparency, and security in various real-life scenarios, revolutionizing traditional contract systems.
Example 3: Complex Question
Q: Discuss the challenges and opportunities of implementing cybersecurity measures in the Internet of Things (IoT) ecosystem.
A: The Internet of Things (IoT) refers to the network of interconnected devices that collect and exchange data. While IoT offers numerous opportunities for innovation and convenience, it also presents significant challenges in terms of cybersecurity.
One of the main challenges is the sheer number of interconnected devices, each potentially creating a vulnerability that can be exploited by malicious actors. Ensuring the security of all devices and the data they generate is a complex task. Moreover, IoT devices often have limited computational power and memory, making it challenging to implement robust security measures.
Another challenge is the lack of standardization in IoT security protocols. Different manufacturers may use different security measures, making it difficult to establish a unified and secure IoT ecosystem. Additionally, IoT devices often have long lifecycles, meaning that security updates and patches may not be regularly provided, leaving them vulnerable to evolving threats.
However, there are also opportunities for implementing cybersecurity measures in the IoT ecosystem. For instance, the use of blockchain technology can enhance the security and integrity of data transmitted between IoT devices. Additionally, implementing strong encryption algorithms and authentication mechanisms can mitigate the risk of unauthorized access.
In conclusion, ensuring cybersecurity in the IoT ecosystem is a complex task with both challenges and opportunities. It requires a collaborative effort from manufacturers, policymakers, and users to establish robust security measures and protect the privacy and integrity of IoT devices and the data they generate.
By thoroughly understanding and practicing the answers to these subjective questions, students can enhance their knowledge and prepare effectively for Grade 12 computer science examinations.
