Define tabbed browsing and explain at length how it works.

What will be an ideal response?

Tabbed browsing allows you to open multiple webpages in a single browser window. Each webpage you open appears in its own tab on the tab row. The active tab appears in the foreground. If you are using a desktop or laptop browser, you likely will be able to see all tabs at once. If you are using a mobile device, you can view your open tabs using a menu command. You can bring a background webpage tab to the foreground for viewing by clicking the tab. Most browsers and devices enable tabbed browsing by default. If the browser allows you to turn off tabbed browsing, each additional webpage you open will appear in a separate browser window. Many browsers have a New tab button on the tab row that allows you display a blank tab and then enter a URL in the Address box, which then opens a webpage in the new tab. If you are using a mobile device, each URL you enter in the Address box may automatically open in a new tab. The new tab appears in the foreground. Depending on your browser or device, when you open a new, blank tab, you may see icons for frequently visited websites, or an option to open tabs that you closed during your last browsing session.
