Netiquette IQ Technical Term of The Day is Vitual Browser

From whatis.com

virtual browser

Part of the Software management glossary:

A virtual browser is a Web browser that is logically isolated from a computer's underlying operating system (OS).

A browser is a software application that allows an end user to look at and interact with information over the Internet. Popular browsers include Google Chrome, Microsoft Internet Explorer (IE), Mozilla Firefox and Apple Safari.

A browser can be virtualized as a standalone application in a virtual machine (VM) or as a virtual appliance. When a browser has been virtualized as a standalone application, it requires the VM to contain a full version of the operating system. When a browser is virtualized as an appliance,  the VM needs just enough operating system (JEOS) to run the browser software. Virtual browsers may be saved locally, accessed over a proprietary network or accessed over the Internet as a public cloud service.

Using a virtual browser can help an end user or network administrator successfully address browser compatibility issues and protect a computer's underlying operating system from Web-based malware. Virtual browsers an be accessed in either anonymous or authenticated modes. In anonymous mode (also called private or incognito mode) all settings, cookies, bookmarks and history are cleared after a session. In an authenticated mode, personal settings, cookies and history are saved and carry over between sessions because they are tied to a specific end user's account. 

Use cases for virtual browsers include:

• Web developers who need to use multiple versions of the same browser for testing puposes.
• Mobile device users who want to run multiple browsers on a smartphone or tablet.
• Employees that require an older (and less secure) version of a specific browser to provide full functionality for a Web-based application.
• Individuals who are concerned about Web-based malware such as poisoned cookies and drive-by downloads.
• Students and employees who want to access websites that a network administrator has blocked.  ===============================
