Remote mirroring: A technique used to replicate data across geographically dispersed sites for data protection and disaster recovery purposes. It involves creating an exact copy of a database, file system, or storage volume at a different location, typically in real-time. This process provides a high level of data redundancy, ensuring that if one site experiences a failure, the data can be quickly retrieved from the mirrored site.

Remote Procedure Call (RPC): A protocol that one program can use to request a service from a program located on another computer on a network. RPC uses the client-server model, where the requesting program is a client, and the service-providing program is the server. It allows inter-process communication and is designed to streamline the development of network-based applications.

Remote rekeying: The practice of updating cryptographic keys on a remote device or system. It is used in secure network environments where encryption is utilized to maintain the security of the encrypted data. Remote rekeying is performed periodically or under specific circumstances, such as when a key is compromised, to ensure the continued security and integrity of the encrypted data.

Remote Terminal Units (RTUs): Devices deployed in the field that interface with sensors or other equipment to collect real-time data, typically in industrial control systems like SCADA. They serve as a focal point for monitoring and controlling physical processes, converting sensor signals into digital data that can be sent to a central system or controller for processing and action. Given their critical role, these units often include features for local decision-making and control, even under network outage conditions.

Remote wipe: A security feature that allows an administrator or device owner to send a command to a device (such as a mobile phone or laptop) to delete data in case the device is lost or stolen. This ensures that sensitive data on the device does not fall into the wrong hands. Depending on the implementation, a remote wipe may delete data selectively (only data managed by the organization) or do a factory reset that wipes all data from the device.

Removable media: Any physical media or device that can be easily removed or detached from a computer or network. It is commonly used for storing, transferring, or backing up data. Examples include USB flash drives, external hard drives, or removable storage cards.
