Duplicate vs. Replication: What's the Difference?

Edited by Janet White || By Harlon Moss || Updated on November 11, 2023
Duplicate means to make an exact copy of something, while replication involves reproducing or repeating a process to achieve similar results

Key Differences

Duplication refers to creating an exact copy of an item or document, emphasizing exactness and precision. Replication, however, involves reproducing a process or system, often in scientific or technical contexts, to achieve similar outcomes.
The act of duplicating usually pertains to tangible items like keys, documents, or artworks. While, replication is often used in the context of experiments, studies, or systems, emphasizing the repetition of a process.
Duplication emphasizes the creation of a one-to-one correspondence in copies. Whereas, in replication, the focus is on repeating a method to verify or study results, which may not be exact copies.
In technology, duplication often involves creating backups or copies of data. Replication in scientific research implies conducting the same experiment to validate or contradict initial findings.
Duplication is often a simpler process, requiring tools or machines to create copies. Replication can be more complex, involving understanding and repeating the underlying processes or conditions.

Identically copied from an original.


The act or process of replicating something.


Existing or growing in two corresponding parts; double.


(Biology) The process by which genetic material, a single-celled organism, or a virus reproduces or makes a copy of itself.


Denoting a manner of play in cards in which partnerships or teams play the same deals and compare scores at the end
Duplicate bridge.


In scientific research, the repetition of an experiment to confirm findings or to ensure accuracy.
