A port replicator is a device designed to provide a simplified way to connect multiple peripherals to a laptop. It connects via a single cable (like USB-C) or a proprietary connector and duplicates the common ports found on a laptop, such as USB, video, and network ports. The description of a device that provides a "one-to-one match for every peripheral connection" fits the function of a port replicator, which aims to "replicate" the laptop's connectivity. While often used interchangeably with "docking station," "port replicator" accurately describes the core function.

A. USB hub: This device only expands the number of available USB ports; it does not replicate other connection types like video or Ethernet.

B. Docking station: While functionally similar, this term often implies a proprietary physical docking mechanism and may add functionality beyond simple port replication. "Port replicator" is a more direct description of the function.

C. KVM switch: A Keyboard, Video, and Mouse (KVM) switch allows a single set of peripherals to control multiple, separate computers, not connect peripherals to one laptop.
