Q & A

  • What is a search engine and how does it work?

    -A search engine is a software program accessible through the internet that searches a database of information based on a user's query. It works by following a process known as crawling, where web crawlers or bots discover new web pages by following links. Once found, these pages are indexed, which involves validating and storing the content in the search engine's database. Finally, the search engine classifies the indexed pages to provide the most relevant results to user queries.

  • What is the difference between a search engine and a web browser?

    -A search engine is a program that searches the internet for information based on user queries, while a web browser is a software application used to access and display web pages. Search engines and web browsers work together, but they are not the same thing. Browsers are necessary for internet access, while search engines help users find specific information on the web.

  • What are the three fundamental principles that all search engines are based on?

    -The three fundamental principles that all search engines are based on are crawling, indexing, and ranking. Crawling is the process of discovering new web pages, indexing is the process of storing and organizing the content of these pages in a database, and ranking is the method used to determine the order in which search results are presented to the user.

  • What is a web crawler and what role does it play in search engines?

    -A web crawler, also known as a bot or spider bot, is a small program used by search engines to discover new web pages by following links from already known pages. When a crawler finds a new page, it scans and collects its content for later processing, which is part of the indexing process.

  • How does the indexing process work in search engines?

    -Indexing is the process where the content of web pages discovered by crawlers is validated and stored in the search engine's database, known as an index. This index acts as a vast library of all the web pages, and a site must be indexed to appear in the search engine's results.

  • What is the purpose of ranking in search engines?

    -Ranking in search engines is the process of selecting the best results and creating a list of pages that will appear in the search results page. It involves using various classification techniques to order the search listings, with the goal of providing the most relevant and useful results to the user.

  • What are some factors that influence the ranking of search results?

    -Factors that influence the ranking of search results include keyword relevance, content quality, backlinks or mentions from other websites, and personal information such as search history and location. These factors help search engines to classify and prioritize results based on what they believe will be most relevant to the user.

  • What are the different types of search engines mentioned in the script?

    -The script mentions conventional search engines like Google, Bing, and Yahoo; private search engines that focus on privacy; vertical search engines that limit searches to a specific category or theme; and computational search engines like Wolfram Alpha, which are dedicated to answering questions related to mathematics and science.

  • Why have private search engines gained popularity recently?

    -Private search engines have gained popularity due to concerns over data collection practices by conventional search engines. They offer users a way to search the internet without compromising their privacy.

  • What is a computational search engine and how is it different from other search engines?

    -A computational search engine, such as Wolfram Alpha, is different from other search engines because it is designed to directly answer questions related to mathematics and science, rather than providing a list of web pages for the user to explore.

  • What is Google's new chatbot called, and what is its purpose?

    -Google's new chatbot is called 'Bard'. It is an intelligent chatbot similar to ChatGPT, developed to compete with Microsoft in the AI business. Google aims to use Bard and other AI developments to improve its services and products, particularly its search engine.
