Short for 'bring your own device'
A phrase that has become widely adopted to refer to mobile workers bringing their own mobile devices, such as smartphones, laptops and PDAs, into the workplace for use and connectivity. Today, many consumers expect to be able to use personal smartphones and mobile devices at work, which is an IT concern. Many corporations that allow employees to use their own mobile devices at work implement a "BYOD policy" to help IT better manage these devices and ensure network security. (Source: Webopedia)
