To what extent are the following computer systems instances of artificial intelligence: a. Supermarket bar code scanners. b. Web search engines.

Artificial Intelligence-It talks about the creation and usage of intelligent machines which can eliminate errors caused by human. In simple words it replaces human intelligence

Explanation:

A Supermarket bar code is a set of characters which are encoded in black and white markings, so that it can be for a machine to scanned via machine or scanner. A Scanner consist of three parts-Lighting system, sensor and decoder. The pulse width of the scanned bars is detected then a simple logic equation is applied to the detected pulse in order to encode the bar code. Thus, no AI technology is being used in Supermarket bar code. In Web Search Engines-The search engines rely on many algorithms to create search results for search queries. Thus the web search engine rely heavily on artificial intelligence. For example: RankBrain Artificial intelligence technology used by Google search engine.
