Google is the name of a search engine that people use billions of times each day. It was invented by Larry Page and Sergey Brin, both of whom worked at Stanford University in the early 1990s.
The company’s mission is to “organize the world’s information and make it universally accessible and useful.”
It is a global corporation that operates in several functional areas, including internet search, advertising technology, cloud computing, and software. It also provides services such as Gmail, Maps, Google Drive, and YouTube.
In 2015, the Google corporation reorganized itself and became a subsidiary of the holding company Alphabet Inc. Its Internet search, advertising, apps, and maps divisions remained under Google, while other ventures, such as home-products company Nest and research lab Google X, were spun off into their own companies.
This reorganization was designed to help the company focus on innovation, especially in artificial intelligence and machine learning. It also allowed it to better compete with other Internet giants such as Facebook and Twitter.
The main function of Google’s search engine is to provide users with relevant results that meet their needs. It does this through a complex algorithm that is constantly changing and improving.
It’s not an exact science, but it does work by analyzing different aspects of each website. For example, it examines how many links the web page has, how well it uses keywords, and whether it is trustworthy.
Using a combination of these factors, Google’s algorithms prioritize the most reliable sources. This is done to avoid providing searchers with web pages that are just repeats of the same questions, or those that have little or no original content.
In addition, it focuses on ensuring that the web pages it serves are easy to navigate for people on mobile devices. Since more people access the Internet on mobile phones than desktops, it’s important to serve them web pages that are optimized for that type of device.
To do this, it collects and analyzes data from websites across the Internet. This includes web pages, email messages, and other forms of communication, as well as data from the devices that users use to access those sites or applications.
This data is collected on a large scale in order to build a detailed understanding of how people use the Internet. It is also used to target ads to people who have expressed interest in specific topics.
Once the data is collected, it is stored in a database, which is referred to as the Google Index. Once the database is full, Google is able to find and display pages that have relevance to a user’s query.
Whenever someone types a keyword into the search box, Google crawls the web and finds as many relevant pages as it can. It then analyzes these pages to determine what they are about and how relevant they are to the searcher’s query.
It then uses machine learning to identify certain signals that indicate a web page is relevant to the user’s query. These include the page’s title, description, content, and other content-related information.
