Google: If any query comes into your mind what you do first, you just tried to google your questions to find out answer. If we didn’t found answer in any book we believe on Google that it has proper answer of your question. Late commer Google becam world’s 70 percent usable search engine.
An Early History of Google
In 1995, two Stanford University computer science students, Larry Page and Sergey Brin, began working on a computer program called BackRub – a search engine that leveraged backlink analysis to track and record data on the internet. (The name “BackRub” was derived from the algorithms ranking that calculated how many “back-links” a web page includes.)
The crown jewel of BackRub was a data collection system known as PageRank, which assigned a web site’s ranking importance by counting the number of pages, mixing in the relevancy of those pages, and linking back to the original web page.
That technology led directly to the cresting of Google, which was self-funded by Page and Bryn working out of their Stanford dormitory rooms on a shoestring budget. The pair used discounted computer parts and maxed out their credit cards before Andy Bechtolsheim, co-founder of Sun Microsystems, wrote a check out to “Google Inc.” for $100,000, to get the company up and running by 1998, when Google was formally incorporated. Bechtolsheim reportedly wrote the check immediately after seeing an early Google product demo on a Stanford professor’s front porch.
Definition of a Search Engine
A search engine is a program that searches the internet and finds webpages for you based on the keywords that you submit. There are several parts to a search engine, including:
- Search engine software such as boolean operators, search fields, and display format
- Spider or “crawler” software that reads web pages
- A database
- Algorithms that rank results for relevancy
Inspiration Behind the Name
The very popular search engine called Google was invented by computer scientists Larry Page and Sergey Brin. The site was named after a googol—the name for the number 1 followed by 100 zeros—found in the book Mathematics and the Imagination by Edward Kasner and James Newman. To the site’s founders, the name represents the immense amount of information that a search engine has to sift through.
Backrub, PageRank, and Delivering Search Results
In 1995, Page and Brin met at Stanford University while they were graduate students in computer science. By January 1996, the pair began collaborating on writing a program for a search engine dubbed Backrub, named after its ability to do backlink analysis. The project resulted in a widely popular research paper titled “The Anatomy of a Large-Scale Hypertextual Web Search Engine.
