This section contains carefully selected MCQs and Previous Year Questions with explanations to help students understand concepts and prepare effectively for examinations, interviews, and competitive tests.
Q: 1Where are GPS devices usually installed? (Choose the most appropriate option from below)
Option C
GPS (Global Positioning System) is a satellite-based navigation system that provides location and time information anywhere on Earth, as long as there is a clear Line of Sight (LOS) to four or more GPS satellites.
GPS devices are commonly installed in cars, taxis, and aircraft for navigation, tracking, and location services. They are also present in many smartphones and other personal devices, but not exclusively.
Q: 2The name of global satellite-based navigation system developed by the United States is?
Option A
Q: 3Using ____________ software one can resize, tag, organize pictures into albums by drag and drop, and can export the pictures for external use.
Option D
Image Organizer software is designed to manage and arrange digital images efficiently. Unlike graphic editing software, which focuses on modifying images, image organizers help you:
Q: 4Global Positioning System uses –
Option A
The Global Positioning System (GPS) uses Code Division Multiple Access (CDMA) technology for signal transmission and access. GPS satellites transmit on the same frequency, but each satellite uses a unique code to allow receivers to distinguish signals. This is the principle of CDMA.
Q: 5Which of the following is not a means / way of transferring money electronically?
Option B
UPI (Unified Payments Interface), IMPS (Immediate Payment Service), and NEFT (National Electronic Funds Transfer) are all means of transferring money electronically in India.
IFSC (Indian Financial System Code) is not a method of money transfer, rather, it is a unique alphanumeric code used to identify a specific bank branch in India.
One additional payment system is RTGS (Real Time Gross Settlement), which is used for large-value transactions and processes transfers instantly in real time without waiting for batch settlements.
Q: 6Which one of the following is not the mode of Social Media?
Option C
Social Media refers to platforms and tools that allow users to create, share, and interact with content online. Common modes of social media:
| SOCIAL MEDIA MODE | EXAMPLES |
|---|---|
| Social Networking Sites | Facebook, Twitter, Instagram |
| Microblogging / Blogging | Blogs, Tumblr |
| Video Sharing | YouTube, TikTok |
| Discussion Forums | Reddit, Quora |
Broadband is not a mode of social media. It is a high-speed internet connection used to access websites and social media but is not itself a social media platform or mode.
Q: 7Choose the correct statements—
(i) Simplex reflex agents take decisions on the basis of the current percepts and past history.
(ii) When uniqueness in the agent’s current state completely determines the next state of the agent, the environment is said to be deterministic.
(iii) The environment is semi-dynamic if the environment itself does not change with the passage of time but agent's performance score does.
Option C
The first statement is incorrect because the simple reflex agents act only on the current percept using condition-action rules. They do not consider past history.
The second statement is correct because in a deterministic environment, the next state is completely determined by the current state and action.
The third statement is correct because in AI terminology, a semi-dynamic environment means the environment state is static, but the agent’s performance score can change, reflecting the passage of time or other external evaluation factors.
Q: 8Who is known as the father of Artificial Intelligence (AI)?
Option C
Artificial Intelligence (AI) is the branch of computer science that deals with creating systems capable of performing tasks that typically require human intelligence, such as reasoning, learning, and problem-solving.
John McCarthy, an American computer scientist, is recognized as the “Father of Artificial Intelligence” because he both coined the term "Artificial Intelligence" in 1955 and organized the Dartmouth Conference in 1956, which is widely considered the birth of AI as an academic field.
| Year | Scientist | Contribution & Relevance to AI |
|---|---|---|
| 1830 | Ada Lovelace | Wrote the first algorithm for Charles Babbage’s Analytical Engine. Considered the FIRST COMPUTER PROGRAMMER. |
| 1936–1950 | Alan Turing | Proposed the Turing Machine (foundation of computation) and the Turing Test (to measure machine intelligence); called the Father of Theoretical Computer Science and AI Concepts. |
| 1955–1956 | John McCarthy | Coined the term “Artificial Intelligence” organized the Dartmouth Conference, and developed LISP, the first AI programming language. Known as the Father of AI. |
| 1956 | Allen Newell & Herbert A. Simon | Created the Logic Theorist (first AI program) and the General Problem Solver (GPS); contributed to early AI system design and problem-solving models. |
| 1960–1970 | Marvin Minsky | Co-founded the MIT AI Laboratory, advanced AI in robotics and cognitive simulation, and popularized AI research globally. |
Q: 9Which of the following algorithms is used for search/optimization in AI?
Option C
In Artificial Intelligence (AI), search and optimization algorithms are used to find the best possible solution from a set of possible states.
The Hill Climbing Algorithm is a heuristic search technique that starts with an initial solution and repeatedly moves to a neighboring state with a better evaluation value until no further improvement is possible. Because it continuously moves toward a better state, it is commonly used for optimization problems in AI.
A Greedy Algorithm selects the locally optimal choice at each step and is generally used in problems like shortest path or minimum spanning tree.
A Recursive Algorithm is a programming technique where a function calls itself to solve smaller subproblems.
Q: 10The first satellite launched by India into space was:
Option B
Aryabhata was India’s first satellite, launched on 19 April 1975 by the Soviet Union using a Kosmos-3M launch vehicle. Marked the beginning of India’s space program under ISRO (Indian Space Research Organisation).
| SATELLITE | LAUNCH YEAR | DESCRIPTION |
|---|---|---|
| Aryabhata | 1975 | India’s first satellite. Scientific experiments in space (X-ray astronomy, solar physics). |
| Rohini (RS-1) | 1980 | First Indian satellite launched by an Indian-made SLV. Remote sensing experiments. |
| INSAT-1A | 1982 | Communication and meteorology satellite. |
| IRS-1A | 1988 | First Indian Remote Sensing satellite for Earth observation. |
| Chandrayaan-1 | 2008 | India’s first lunar mission. |
