“Node-Restricted” or “Node-Locked” refers to a type of software licensing or digital rights management that restricts the use of the licensed software to a specific computer or device.
In this licensing model, the software can only be installed and run on the designated computer or device, which is typically identified by a unique hardware identifier, such as a MAC address or a serial number. Attempts to use the software on a different computer or device will result in an error or the software may not function properly.
Node-restricted or node-locked licensing is commonly used in software applications that are intended for use on a specific machine, such as CAD (computer-aided design) software, scientific or engineering simulation software, or software used for industrial automation. This type of licensing model provides greater control over the distribution and use of the software, and can help prevent unauthorized copying or distribution of the software.
