What is Google?
Google is a search engine that is most popular in the world. It is a multinational technology company based in California, US, founded by Larry Page and Sergey Brin. It has a mission to organize the world’s information and make it universally accessible and useful. It also offers many other online services and tools such as YouTube, Gmail, Maps and Google Drive.
The word “Google” is actually a misspelling of the word googol, which means a very large number. In mathematics, a googol number is 1 raised to the power hundred (or 1). This number is also used as a hexagram symbol in cryptography and other special mathematical applications.
A search engine is an application that searches the Internet for text and then displays the results of those searches in a user-friendly format. In order to perform a search, you must provide keywords that describe what you are looking for. Then, your keywords are compared with the millions of other pages on the Internet that contain those keywords.
There are a variety of different search algorithms and formulas that allow Google to determine how likely it is that a particular site contains what you are searching for. This allows Google to offer you search results that are relevant to your needs, including alternative words or phrases that may have been overlooked by other sites. It also helps prevent searchers from seeing irrelevant or unsafe websites, and specializes in eliminating SPAM.
Founded in 1998, Google was established by two computer science Ph.D. students at Stanford University, Larry Page and Sergey Brin. They created a search algorithm that ranked Web pages not by their content and keywords, but by how many other Web pages linked to them. This strategy produced more useful results and quickly increased Google’s Web search market share.
In September 2001, Google patented its search algorithm, which was later renamed “PageRank.” This system is now used by most other search engines, as well.
A search engine’s goal is to find the most relevant and most up-to-date information for a specific query. The process includes crawling and indexing the vast amounts of data available on the Internet, analyzing how frequently keywords appear in various locations, and then arranging the information retrieved by these methods into a user-friendly format.
The results that are returned by a search engine are then ordered according to a priority rank system called “PageRank.” This order is determined using a combination of mathematical calculations and human judgment. The priority rank system is based on a number of factors, such as how relevant the results are to a user’s search terms, how often other users link to a site, and how popular the site is overall.
As of 2016, Google has over 30 billion web pages, with more than 2 trillion documents contained in its indexes. The company’s indexes are updated constantly, ensuring that they include the most current content. The information in the indexes is indexed as text, images, audio, and video. The information is then stored in a database. The database is searchable by the users and is updated automatically as new content becomes available. The company has a large team of web crawlers and other software to maintain its indexes. The company’s search engine is a major part of its business model and provides a significant portion of its revenue.
