AI Summary
An AI-generated summary of this video lecture.
This lecture segment introduces the concept of Search and Meta Search Engines. It defines a search engine as a web-based tool enabling users to locate information on the World Wide Web. The instructor explains that these engines utilize automated software applications, referred to as robots, bots, or spiders, which travel along the Web to create a searchable index. Popular examples such as Google, Yahoo!, and MSN Search are cited. The session concludes with a multiple-choice question from a 2018 exam paper designed to test the student's understanding of the primary function of a search engine.

0:00 – 2:00 00:00-02:00
The instructor begins by defining a search engine as a web-based tool for locating information on the World Wide Web. Visible text lists popular examples including Google, Yahoo!, and MSN Search. The explanation details how search engines utilize automated software applications, specifically robots, bots, or spiders, that travel along the Web following links to create a searchable index. The instructor writes annotations on the screen, noting "WWW -> collect data" and "WWW -> specific region". The lecture then focuses on Google, describing it as the best search engine in the world and a web portal containing services like Mail, Books, Translate, MAP, Google+, and YouTube. Finally, the instructor scrolls to Yahoo, noting it is owned by Yahoo and headquartered in Sunnyvale, California, and was the fourth largest search engine worldwide as of October 2018.
2:00 – 2:14 02:00-02:14
The instructor transitions to a multiple-choice question labeled "Q. Search engine is used (UPLT - 2018)". The question asks for the primary use of a search engine. The visible options are: A. to search document on web, B. to search the file on host computer, C. to search data in a file, and D. None of the above. The instructor underlines each option sequentially, likely explaining why the first option is the correct answer based on the definition provided earlier in the lecture.
The video provides a comprehensive introduction to search engines, defining them as tools that use spiders to index the web. It highlights major players like Google and Yahoo, detailing their services and origins. The lesson culminates in a practical application of this knowledge through a past exam question, ensuring students can identify the correct context for using search engines versus local file systems.
