About this topic

AI terminology is used loosely enough that the same word often means several different things in one conversation. This quiz keeps the distinctions: robots versus AI, learning from data versus following instructions, and what a neural network borrows from biology and what it does not. It covers foundational concepts, real applications and the fiction that shaped public expectation. The explanations describe what systems actually do today rather than what they are promised to do.

1What does AI stand for?
- A Artificial intelligence Correct
- B Automated interface
- C Advanced iteration
- D Applied informatics
Answer: A. Artificial intelligence

Why: The term dates from a 1956 workshop at Dartmouth College. It covers a broad range of techniques rather than any single technology.
2A robot is best defined as what?
- A A machine able to carry out tasks automatically Correct
- B Any computer program
- C A humanoid figure specifically
- D A remote control device only
Answer: A. A machine able to carry out tasks automatically

Why: Robots act in the physical world and need not resemble people. Most working robots are industrial arms bolted to a factory floor.
3Machine learning refers to what?
- A Programs written entirely by hand
- B Hardware that repairs itself
- C Systems that improve their performance from data Correct
- D Machines that teach people
Answer: C. Systems that improve their performance from data

Why: Rather than being given explicit rules, the system derives patterns from examples. Its output quality depends heavily on the data it was trained on.
4An algorithm is what?
- A A data storage format
- B A programming language
- C A type of computer chip
- D A defined sequence of steps for solving a problem Correct
Answer: D. A defined sequence of steps for solving a problem

Why: Algorithms long predate computers, including methods for long division. The word derives from the mathematician al-Khwarizmi.
5The Turing test was proposed to assess what?
- A Whether a robot can walk
- B How fast a computer calculates
- C How much memory a system uses
- D Whether a machine's responses are indistinguishable from a human's Correct
Answer: D. Whether a machine's responses are indistinguishable from a human's

Why: Alan Turing proposed it in 1950 as a way to sidestep defining thought directly. Whether it measures anything meaningful remains debated.
6A neural network is loosely inspired by what?
- A Ant colonies
- B The structure of connections in the brain Correct
- C The circulatory system
- D Crystal formation
Answer: B. The structure of connections in the brain

Why: Artificial networks use layers of connected units with adjustable weights. The resemblance to biological neurons is loose rather than literal.
7"Training data" refers to what?
- A The examples a model learns patterns from Correct
- B The hardware specification
- C The final output
- D The instructions a programmer writes
Answer: A. The examples a model learns patterns from

Why: Models learn statistical patterns from their training data. Bias or gaps in that data are reproduced in the system's behaviour.
8Industrial robots are most widely used in which sector?
- A Hospitality
- B Retail sales
- C Publishing
- D Manufacturing Correct
Answer: D. Manufacturing

Why: Manufacturing, especially automotive assembly, accounts for the largest share. They excel at repetitive, precise tasks in controlled environments.
9Self-driving vehicles depend principally on what combination?
- A Sensors and software interpreting the surroundings Correct
- B Remote human drivers only
- C Roadside magnets
- D Satellite navigation alone
Answer: A. Sensors and software interpreting the surroundings

Why: They combine cameras, radar and often lidar with software that interprets the scene. Unpredictable conditions remain the hardest unsolved part.
10Isaac Asimov is known in this field for what?
- A Building the first robot arm
- B Devising fictional laws of robotics Correct
- C Inventing machine learning
- D Founding a robotics company
Answer: B. Devising fictional laws of robotics

Why: His Three Laws appeared in fiction from 1942 and shaped how the public imagines robot safety. They were written as story devices, not engineering standards.
