Dock
A computer dock is a device that expands the functionality of a laptop by connecting it to a desktop-like setup of peripherals, such as monitors, keyboards, mice, and printers, with a single connection. Another type of "dock" is a software-based application launcher in operating systems like macOS, which provides quick access to frequently used apps and files.

Connection: Connects to a laptop through a single cable, commonly USB-C or Thunderbolt.
Dock (software)
Purpose: A user interface element in operating systems (like the macOS Dock) that provides quick access to applications, documents, and folders.
