duplicator

A duplicator is a device or process that creates copies of an original item. The term is used across fields to describe equipment or methods that reproduce content, structure, or material, often with the goal of increasing quantity while preserving fidelity.

In data storage and computing, a disk duplicator or hardware duplicator is a standalone device that copies data from a source drive to one or more target drives without a host computer. It performs bit-for-bit cloning and can include features such as verify passes, formatting options, and support for different interface standards (SATA, USB, etc.). These systems are used for rapid deployment of identical software images, operating systems, or firmware across many devices, particularly in manufacturing facilities and IT departments. Some models offer automation, scheduling, reporting, and password protection for job management and security.

In media production, stand-alone duplicators are used to reproduce optical discs, such as CDs or DVDs, for distribution. They enable mass production with reduced manual handling and faster turnaround times.

In biology, duplication refers to the natural process of DNA replication, in which a cell copies its genetic material before division. This process involves enzymes such as helicases and DNA polymerases, ensuring a faithful copy is produced for each daughter cell. The term duplicator is not commonly used to describe this cellular mechanism, but the concept of creating a copy is central to genetic replication and propagation.
