What tool can be used to remotely connect to another computer for support purposes?

Remote Desktop Protocol (RDP) is designed specifically to allow a user to connect to another computer over a network or the internet, enabling remote technical support, access to applications, and file manipulation. When a technician uses RDP, they can see the desktop of the remote computer, control it as if they were sitting in front of it, and perform troubleshooting or maintenance tasks seamlessly.

This capability is crucial for desktop support technicians who often need to diagnose issues, perform software installations, or configure settings without having to be physically present at the user's location. RDP is effective because it provides a full graphical interface, which enhances the technician's ability to interact with the remote system.

Other options like File Transfer Protocol (FTP) and Simple Mail Transfer Protocol (SMTP) serve different purposes; FTP is primarily for file transfer, while SMTP is used for email transmission. A Virtual Private Network (VPN), while useful for securing remote connections and encrypting data traffic, does not inherently provide the remote control features that RDP does. Hence, RDP is the specifically tailored tool for remote access and support scenarios.
