Web browser
A web browser (often known as a browser; hereinafter, the Browser) is an end-user application that allows for browsing web documents published at the World Wide Web. To request the Browser display some website, a user enters into the Browser the website's hostname. Then, the Browser utilizes DNS to locate the sought website in the World Wide Web and to get its landing page's web document in order to display this webpage in the Browser.
Browsers vs search engines
The Browsers are often confused with search engines because those two work in pair. For an end-user, a search engine is just any website that provides the user with other website's search-specific data that this search engine stores. The user no longer needs any search engine after he or she chooses which website they would like to access.
