Search engines are software that locates information on a search query. A search engine has three main processes: crawling, indexing, and serving. Crawling is the process of finding new or updated pages. Each result on a search engine is a website with a URL(uniform resource locator). Search engines find results through often complicated algorithms. Algorithms and data structures are a central part of computer science. Generally speaking, an algorithm is just a set of instructions for solving a problem or accomplishing a task. A basic algorithm that is famous in computer science is the fizzbuzz algorithm. In the fizzbuzz algorithm, everytime a number is divisible by three, fizz is printed on the screen. If a number is divisible by 5, then buzz is printed on the screen and if a number is divisible by 15(divisible by both 3 and 5), 15 is printed on the screen.
