What device allows a laptop to connect to additional peripherals easily?

A docking station is designed specifically to expand the functionality of a laptop by allowing it to connect to various peripherals seamlessly. It typically provides multiple ports including USB, HDMI, Ethernet, and audio jacks, enabling the user to connect monitors, keyboards, mice, printers, and network cables all through a single connection to the laptop. This enhances productivity by allowing users to quickly dock and undock their laptops, while still providing them access to a fully set up workstation.

In contrast, other devices serve different purposes. For example, a modem is primarily used to connect to the internet, while a router is for distributing that internet connection wirelessly or through additional connections. A hub, although it can connect devices, does not provide the same level of functionality and integration as a docking station specifically designed for laptops. Thus, the docking station is the most appropriate device for this context.
