Understanding Virtual Desktops
What is a Virtual Desktop?
A virtual desktop is a computing environment that mimics an individual computer’s desktop through virtualization technology. It allows users to access their desktop interface from any device connected to the internet. This means that whether you’re using a personal laptop, a shared tablet, or even a smartphone, you can enjoy the same desktop experience as if you were sitting in front of your own workstation. Essentially, the user’s desktop is hosted on a server, providing a sandboxed experience that can be accessed remotely.
By leveraging a virtual desktop infrastructure (VDI), organizations enable employees to work remotely with secure access to applications and data. This not only promotes flexibility but also enhances security, as sensitive information is primarily stored on the server rather than individual devices.
