Q.1) ABOUT GOOGLE OLD
NAME BACKRUB..



The roots of Backrub
Work on the BackRub search engine began in 1996. It was a research project of Larry Page, who studied at Stanford University at the time and was part of the team that worked on the Stanford Digital Library Project (SDLP). This project had set itself the goal of developing technologies which could create a universal digital library. As part of his thesis, Larry Page took up the issue of linking. His reflections on understanding link structure as a huge graph, later led to the development of the still significant PageRank algorithm.

Development
Page named his project BackRub. Later, Sergey Brin, who had also worked on a similar study and research area, joined Page and from then on supported him in the development of the search engine.

First, the search engine returned a list of backlinks, whose ranking was designed depending on their importance. The two developers quickly realized that a search engine that would be based on PageRank would yield better results than existing technologies. At that time, search engines were exclusively fixated on how frequently a searched keyword appeared on a web page. Page and Brin wanted to build BackRub on the principle that the websites which had the most links would be the most relevant.

Growth
After Backrub began indexing websites in March 1996, the index grew very quickly. By August 1996, some 75 million pages had been indexed which occupied a total of 207 GB when combined. Around 30 million HTML pages were among them, but even more e-mail addresses. In the year Google was created, Backrub had already indexed 25 million pages. Google Inc., was finally established on September 4, 1998 and the renaming of the search engine from Backrub to Google was decided.


Q.2)TELL ME ABOUT NEWTON..​

Answer 1

Answer:

A newton is how much force is required to make a mass of one kilogram accelerate at a rate of one metre per second squared. 1 N is the force of Earth's gravity on an apple with a mass of about 102 g. On the Earth's surface, a mass of 1 kg pushes on its support with an average force of 9.8 N.

Answer 2

Explanation:

Sir Isaac Newton PRS (25 December 1642 – 20 March 1726/27) was an English mathematician, physicist, astronomer, theologian, and author (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution
