1. What is AI? (1 Mark)
Answer: AI is the art and science of developing machines running on intelligent algorithms that make them capable of thinking, acting and learning like human beings.
2. Who was coined the term Artificial Intelligence (AI)? (1 Mark)
Answer: The term Artificial Intelligence was first coined by John McCarthy in 1956. He was a Stanford researcher.
3. In simple, what is Artificial Intelligence? (1 Mark)
Answer: In plain and simple words, the ability of a machine to think and learn is called Artificial Intelligence.
4. What is McCarthy’s definition of AI? (1 Mark)
Answer: According to McCarthy “AI is the science and engineering of making intelligent machines.”
5. What is the AI field? (1 Mark)
Answer: The AI field refers to the study of the principles, concepts and technology for building such machines and systems that should think, act and learn like humans.
6. Why AI is important today? (1 Mark)
Answer: Today’s huge amount of data is uploaded on internet daily, and it require an intelligent applications to process these data better way. With the help of AI, computers are able to process complex problems in very simple way.
7. What are the challenges in the path of true AI? (1 Mark)
Answer: The major challenges in the path of true AI are –
(a) Retain the facts as knowledge
(b) Recall the knowledge in a situation
(c) Think, analyse and apply logic.
(d) Make useful and accurate predictions
(e) Make decisions and upgrade their intelligence algorithm themselves.
8. What is Smart Home? (1 Mark)
Answer: A smart home is a residence equipped with several Internet-enabled interconnected devices using IoT that automate tasks normally handled by humans.
9. What is Smart Device? (1 Mark)
Answer: A smart device, also known as thing, is an electronic device that can connect, store and interact with user and other smart devices.
10. What is IoT? (1 Mark)
Answer: IoT stands for Internet of Things. IoT is a technology that forms a network of smart devices (things).
11. What are domains of AI? (1 Mark)
Answer: AI is a mix of three domains. These are –
- Data Science (Data)
- Computer Vision
- Natural Language Processing (NLP)
12. What is Data Science?
Answer: Data science is a field that uses scientific methods, processes, algorithms, and systems to extract knowledge and insights from many structural and unstructured data.
13. How an AI powered refrigerator knows in advance that what type of food you would prefer in summers?
Answer: Because it has all your past data and it applied data science methods to determine your choice in summer.
14. What are the different categories of data science?
Answer: Data science is related to –
- Data mining
- Machine learning
- Big Data
15. What is Data Mining?
Answer: Data Mining is a process of finding potentially useful patterns from huge data set.
16. What is Machine Learning?
Answer: Machine Learning is a process of automatic learning of computers and machine by discovering insights from data with experience.
ML is also used to make predictions about future outcomes.
17. What is Big Data?
Answer: Big Data refers to huge amounts of data, which is regularly growing at an exponential rate, e.g., data of social media.
Big data can not be handled without AI.
18. What is Computer Vision?
Answer: Computer Vision is a field of artificial intelligence that trains computers to interpret and understand the visual world.
19. How computer vision works?
Answer: Computer Vision, uses the digital images from cameras and videos and deep learning models, computers and machines can accurately identify and classify objects and then react to what they see.
20. Due to which technologies, your AI powered lock with camera can identify people and then opens door only for authentic members.
Answer: Computer Vision
21. What is Natural Language Processing?
Answer: Natural Language Processing is a subfield of linguistics and AI concerned with the interactions between computers and human languages in the form of speech input and speech output.
22. Explain the different categories of NLP?
Answer: NLP has two categories.
- Natural-Language Understanding: It helps machine recognise natural speech and understood its meaning. For example, Google Assistant, Siri, Alexa etc.
- Natural-Language Generation: It helps in producing a response in natural language. It is closely related to Automated Speech recognition. For example, Cortana, Google Assistant, Siri, etc.
23. What pros and cons of Artificial Intelligence?
Answer: Pros and Cons of Artificial Intelligence are –
| Pros | Cons |
| (i) It has less room for errors. (ii) It exhibits right decision-making. (iii) It can work in risky situations. (iv) It can work 24×7 . | (i) It is expensive to implement. (ii) AI depends on hardware’s and software’s efficiency. (iii) It can replace humans in some cases only. (iv) Can perform restricted work only. |
