To what extent are the following computer systems instances of artificial intelligence:
(a) supermarket bar code scanners.
(b) web search engines.
(c) voice-activated telephone menus.
(d) internet routing algorithms that respond dynamically to the state of the network

Supermarket bar code scanners and Voice-activated telephone menus are not instances of artificial intelligence

Explanation:

(a)Supermarket bar code scanners are only able to read the code however they are not able to perform any kind of machine learning techniques to be able to learn a sequence from the codes. As machine learning is a important part of artificial intelligence (AI) so they are not instances of AI. Similarly for Voice-activated telephone menus they could only display and cannot perform any intelligent task.

Web search engines and Internet routing algorithms are very dynamic and intelligent in processing and retrieving information to the end user.

So they are instances of AI.
