4. A search engine is like a helpful tool on the internet. It helps you find things online, like websites, information, and pictures. Functions Of Search Engine Indexing: Search engines crawl the web and create an index of web pages. Ranking: They use algorithms to rank these pages based on relevance to user queries. Retrieval: Search engines provide search results in response to user queries. Introduction

5. Components of Search Engine 1)Web Crawler 2)Database 3)Search Interfaces 4)Ranking Algorithms

6. Web Crawler • Web Crawler is also known as a search engine bot, web robot, or web spider. It plays an essential role in search engine optimization (SEO) strategy. • It is mainly a software component that traverses on the web, then downloads and collects all the information over the Internet.

7. Database • The search engine database is a type of Non Relational Databases. It is the place where all the web information is stored. It has a large number of web resources. Some most popular search engine databases are Amazon Search Service and Splunk. • There are the following two database variable features : • 1) Size of the database • 2) The freshness of the database

8. Search Interfaces • The Search Interface is one of the most important components of Search Engine. It is an interface between the user and the database. It basically helps users to search for queries using the database.

9. Ranking Algorithms • The ranking algorithm is used by Google to rank web pages according to the Google search algorithm. • There are the following ranking features that affect the search results - • Location and frequency • Link Analysis • Clickthrough measurement

10. How Search Engine Works?

11. There are two entities in client-server Architecture. They are - • Client • Server • 1) CLIENT • The entity that request the resource . • In the above example the devices which are requesting for • the resource over the internet like laptop , mobile are the • clients.

12. 1)SERVER • The entity which has the resource and which can give the • desired content or which responds to the responds to • the request is known as server • The server plays a critical role in facilitating the exchange of data and • information on the internet, serving as a central hub for processing • and delivering content. • In the above example we can see the server which is • receiving the client’s request.

14. The Internet has revolutionized global technology by connecting the entire world, following specific communication architecture and structure. • The popular is the client-server architecture which is a computing model, where the server hosts, distributes and controls the majority of the resources as well as services to be used by the client. • Structural designs consist of client systems connected to central servers via the internet. These systems share computing resources.

15. The client-server architecture is also termed as a network-computing structure because every request and their associated services are distributed over a network. • So now the question is how the thing works? • In the client-server architecture, when the client computer sends a request for data to the server through the internet, the server accepts the requested, process it and deliver the data packets requested back to the client. One special feature is that the server computer has the potential to manage numerous clients at the same time. Also, a single client can connect to numerous servers at a single timestamp, where each server provides a different set of services to that specific client.

16. Advantages of Search Engine Searching content on the Internet becomes one of the most popular activities all over the world. In the current era, the search engine is an essential part of everyone's life because the search engine offers various popular ways to find valuable, relevant, and informative content on the Internet. A list of advantages of search engines is given below – 1. Time-Saving Eliminate the need to find information manually. Perform search operations at a very high speed.

17. 2. Variety of information The search engine offers various variety of resources to obtain relevant and valuable information from the Internet. By using a search engine, we can get information in various fields such as education, entertainment, games, etc. The information which we get from the search engine is in the form of blogs, pdf, ppt, text, images, videos, and audios. 3.Precision All search engines have the ability to provide more precise results.

18. Disadvantages of Search Engine There are the following disadvantages of Search Engines • Sometimes the search engine takes too much time to display relevant, valuable, and informative content. • Search engines, especially Google, frequently update their algorithm, and it is very difficult to find the algorithm in which Google runs. • It makes end-users effortless as they all time use search engines to solve their small queries also.

19. CONCLUSION Search engine allows the user find the information they need. Search engine is designed to relevant results. The primary goal is to provide high quality search results over a rapidly growing world wide web. Search engines will continue to expand and improve the services they provide. Search engines will continue to expand and improve the services they provide, enhancing the user experience and adapting to evolving online content.
