STEM STEM Section Review 12.1 Sergey Grin and Larry Page created Google while pursuing their PhDs at Stanford University. Google makes use of massive databases and has the most sophisticated search algorithms of any programs written. Its mission is “to organize the world’s information and make it universally accessible and useful.” Google runs more than one million servers in data centers around the world and processes over one billion search requests per day. Each data center is composed of high- performance computers that run all the time. Google maintains an index of websites, which is a large database. A Google search is a basic query on the index (database). According to Google, this database exceeds 95 petabytes in size, or nearly 100 million gigabytes. Google also can reach other databases of information that are not links, but can be accessed via queries. Titans of Technology
