search engine


Today search engine has become a part of our daily life. Now the time is gone when people used to go to Google to study, today people find the solution of their every small and big problems on Google first. There are many types of search engines and the way each search engine works is different. everyone's secret
There is a mathematical formula called an algorithm.
This Algorithm decides that which website will come first and after the search, that is, how much will be the ranking of a website on the result page, it is decided by the algorithm itself. Tips are given to increase the ranking, but complete information is not given about their algorithms so that no one can use them in a wrong way.
search engine
The main function of the search engine is to find information by visiting different web pages, organize them and rank them according to the quality of the content.

There are mainly four types of search engines-
(i) Crawler-based search engines
(ii) Web directories
(iii) Hybrid search engines
(iv) Meta search engines

Example of Search engines:

Engelbert presents computer processes visually on the screen.

 Television has traditionally been discredited as having an empty, glowing goggle box—"chewing gum for the eyes."
 However, in the twenty-first century people are more likely to be Googling on computer screens than on television sets.
 This is strange, because unlike televisions, computers did not originally include a screen. When they were first created, computers only processed data from manually inserted punch cards. Other than some mechanical whispers, they offered no real visual clue as to what they were doing. To have the most basic understanding of what a computer was doing at any point in its processing, a person needs to have a fairly advanced degree in mathematics.
This privilege has become accessible to all since the invention of the Graphical User Interface (GUI).
 The man who led the way was Douglas Engelbart (b. 1925). Inspired by an essay by Vannevar Bush he read in The Atlantic Monthly magazine, Engelbart led the development in a pioneering new human/computer interaction system known as the "on-line system", or NLS. The first to employ a display screen, it used vector graphics, clickable hypertext links, and screen-windows, all controlled by a cursor. When it was performed in 1968, it created a huge sensation.
Engelbert's radical ideas were further developed by Alan Kay (6. 1940) of the Palo Alto Research Center, who introduced the idea of ​​a graphical representation of computing functions. The folders, menus, and overlapping windows that we are familiar with today evolved from the excellent work of Kay. Together, they changed how we view computers.

Apple's Lisa computer was the first to have a GUI, but its $10,000 price scared off most potential customers.

  Despite being a pioneer offering an allied console while working for US defense contractor Sanders, Ralph H. Baer (b. 1922) had for some years given a new form of entertaining and entertainment (Bayer himself was considering possible ways of playing the game, who is reported to have liked) these early games through a television set. from. In 1966 they sat down and, in today's more advanced systems), it was not a big seller.
 Four short pages, produced a document he called ineffective marketing to potential buyers and "the magna carta of video games". This document the high price of $100 was prohibitive.
 To form the basis of the first video game console. The video game was never actually exposed to the public. At first he built his prototype in his spare time, after playing Consciousness, until another inventor, but as he developed his ideas his employer introduced the Magnavox ping-pong game. Ko, realized an arcade version that big money could be made, so he called Pong, which became extremely popular. Backing his project from the start. Then, with video games becoming a billion dollars, a Bayer's "brown box" appeared in the industry two years later and an integral part of leisure time—all this 1968. It featured seven sports: table tennis, volleyball, stemming from Bayer's little brown box. The SB used handball, soccer, golf, checkers, and even target shooting, the first prototype light guns.
 Placed in front of the television to simulate scenes and in-game obstacles. The system was licensed for 1 1972 Magnavox Odyssey System included Magnavox and released in 1972 as the Odyssey System.

 PSLV-C52 is designed to orbit Earth Observation Satellite (EOS-04), weighing 1710 kg, in a 529 km Sun Synchronous Polar Orbit. EOS-04

 The PSLV-C52 mission will also carry two small satellites as co-passengers including a student satellite (INSPIRESat-1) from the Indian Institute of Space Science and Technology (IIST) in collaboration with the Laboratory of Atmospheric and Space Physics at the University of Colorado, Boulder. is included. and a Technology Demonstrator Satellite (INS-2TD) of ISRO, which is a precursor to the India-Bhutan Joint Satellite (INS-2B).
 EOS-04 is a radar imaging satellite designed to provide high quality images in all weather conditions for applications such as agriculture, forestry and plantation, soil moisture and hydrology, and flood mapping.

 The countdown process of 25 hours and 30 minutes for the launch will begin at 04:29 hrs on February 13, 2022 after authorization by the Launch Authorization Board.
