What is Remote Desktop Protocol (RDP)?
Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft that allows users to connect to another computer over a network connection. RDP enables users to remotely control a Windows computer, providing an interface that replicates the experience of being physically present at the machine. It is widely used for telecommuting, technical support, and remote administration.
RDP operates by sending keyboard and mouse inputs from the client to the remote machine and transmitting the screen image back to the user’s device. The protocol supports multiple channels, allowing for various types of data to be transmitted concurrently, including audio, video, and clipboard data. This functionality makes it an effective solution for users who need to access applications and files remotely.
What do I need to use RDP?
To use RDP, both the local and remote computers must support the protocol. The remote computer generally needs to be running a version of Windows that includes the Remote Desktop feature, such as Windows Professional or Enterprise editions. The local computer can be any device that supports RDP client software, including Windows, macOS, Linux, or mobile devices.
Additionally, proper network configuration is essential for a successful RDP connection. This includes ensuring that the remote desktop feature is enabled on the host machine, appropriate firewall settings allowing RDP traffic, and a stable internet connection.
