What Is Screen Sharing and How Does It Work?
Screen sharing, also known as desktop sharing, is the practice of sharing the contents of your screen with another device or multiple devices. This can include all the elements on a screen or simply one window, allowing for complete control over the visibility of your desktop and a guarantee of privacy. By sharing your screen you have the ability to show friends, colleagues or clients any media that is on your device without ever having to go through a lengthy transfer process; this can include presentations, documents, images, and even videos. What’s more, screen sharing allows the recipient to not only view the material on the shared device but watch as the user interacts with it, navigating the interface and making changes.
Screen sharing works by breaking down the information depicted on the device screen into encoded packets of information and sending them across the internet to another device. The recipient device then rebuilds the image received from the other screen. Modern screen sharing software is smart enough to both compress the data to minimise bandwidth requirements and carefully monitor activity on the screen: the software will only transmit information when a change or movement occurs. This further helps to improve the connection stability and image quality.
