How do I disconnect from a remote session safely?

Yes, you can access multiple remote computers from one device, depending on the software. Tools like Microsoft Remote Desktop, TeamViewer, and Splashtop allow you to manage and switch between multiple remote connections from a single device. You may need to configure each computer separately, and some tools offer a management interface to keep track of multiple machines.

Data usage depends on the resolution and frame rate of the remote session, as well as the amount of interaction:

Basic remote access sessions with minimal activity can use about 500 MB to 1 GB per hour.
High-definition sessions, including streaming video or graphic design work, can use 2 GB or more per hour.
Reducing screen resolution and limiting video or graphic-heavy applications can help lower data usage.

To troubleshoot connection issues:

Check network connectivity: Ensure both the remote and local computers are connected to the internet.
Firewall settings: Verify that the firewall is not blocking the Remote Desktop or remote access ports (usually port 3389 for Windows RDP).
IP address: Confirm you are using the correct IP address or hostname.
Remote access permissions: Ensure remote access is enabled on the target computer.
Software updates: Check for updates to your remote access software, and update if necessary.
Restart the remote service: If possible, restart the Remote Desktop service or the entire system to reset the connection.

Yes, Remote Desktop can work from anywhere, as long as he remote computer is powered on and connected to the internet. You have the correct IP address or network credentials to access the remote machine. Firewalls, network settings, and VPNs (if required) are properly configured to allow remote access from external networks.
