5. How does NLP benefit the healthcare sector?
Ans. NLP can be used to analyze medical records and detect patterns that can help with disease diagnosis and treatment.
6. Enumerate various NLP techniques.
Ans. The various NLP techniques are as follows:
• Text analysis: It involves extracting relevant information from text data, such as named entities, keywords, and themes.
• Sentiment analysis: It involves determining the emotional tone of a piece of text, such as positive, negative, or neutral.
• Speech recognition: It involves converting spoken words into text data.
• Machine translation : It involves translating text data from one language to another.
7. What do you mean by the term immersive experience?
Ans. Immersive experience refers to a type of technology that creates a sense of immersion or presence in a simulated or virtual
environment, typically through the use of advanced graphics, sound, and other sensory stimuli.
8. How is AI helpful in the field of robotics?
Ans. AI algorithms and techniques can help robots become more intelligent, adaptive, and capable of performing complex tasks.
9. Describe the three characteristics, or 3 V’s of big data.
Ans. The three characteristics of big data, or the 3 V’s are:
(i) Volume: Big data refers to datasets that are too large to be stored, processed, and analyzed using traditional methods.
This can include data from a wide range of sources, such as social media, sensors, and transactional systems.
(ii) Velocity: Big data is generated at an unprecedented speed, often in real-time or near real-time. This requires new tools
and techniques to handle the high data flow rate and ensure timely analysis.
(iii) Variety: Big data comes in many different forms, including structured, semi-structured, and unstructured data. This can
include text, audio, video, and images, as well as traditional data formats such as spreadsheets and databases.
10. State an application of the following IOT sensors?
(i) GPS Sensors
(ii) Pressure Sensors
(iii) Motion Sensors
Ans. (i) GPS sensors detect location and are used in navigation systems, fleet management systems, and asset tracking systems.
(ii) Pressure sensors measure pressure and are used in industrial control systems, automotive applications, and building
automation systems.
(iii) Motion sensors detect movement and are used in security systems, smart homes, and gaming systems.
11. How can IOT help with energy management in cities?
Ans. IoT sensors can be used to monitor energy consumption in buildings and public spaces. This data can be used to optimize
energy usage and improve energy efficiency.
12. What advantages does cloud computing have over traditional on-premises computing?
Ans. The advantages of cloud computing are scalability, cost-effectiveness, flexibility, and reliability.
13. Name the three service models of cloud computing.
Ans. Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
14. Differentiate between private and public clouds.
Ans. Private cloud is a cloud infrastructure that is owned and operated by a single organization and made available to internal
users over a private network. A public cloud is a cloud infrastructure that is owned and operated by a cloud service provider
and made available to the public over the Internet.
15. Identify a significant problem that grid computing users face. How is it addressed?
Ans. One of the key challenges in grid computing is managing the complexity of coordinating resources across multiple
organizations and locations. To address this challenge, various software tools and protocols have been developed to
facilitate resource sharing and management. Examples of such tools include the Globus Toolkit and the Open Grid Services
Architecture (OGSA).
