Many beginners on the web confuse search engines and browsers. Let's make it clear: A browser is a piece of software that retrieves and displays web pages; a search engine is a website that helps people find web pages from other websites. The confusion arises because, the first time someone launches a browser, the browser displays a search engine's homepage. This makes sense, because, obviously, the first thing you want to do with a browser is to find a web page to display. Don't confuse the infrastructure (., the browser) with the service (., the search engine). The distinction will help you quite a bit, but even some professionals speak loosely, so don't feel anxious about it.
