The Address bar in your web browser is where you type the website address ('URL') of an internet web site you wish to see. You can move your cursor into the Address Bar by keeping 'ALT' on your keyboard pressed down while you press the letter 'D'.
The space on the top of your browser that lets you type in the place a website lives, or its address, and takes you there. When you browse to a website you can look in the address bar to see its address.
Same as Location Bar. The box near the top of your browser window that displays the URL of the page you are viewing. (See example.) If you know the URL of a site your want to visit, you may type the URL directly into the address bar box, then hit "Enter" or "Return" to go directly to the site. You may also type search terms into the box and hit "Enter" or "Return"; the browser will automatically perform a search using its configured search engine.
