Almost all new laptops feature USB-C ports as the world ditches slower USB-A ports in favor of this faster, more versatile connection standard. Some modern laptops only have USB-C ports, so having a USB-C hub (a docking station) is essential. It allows you to easily connect a wired USB-A keyboard, mouse, or an older printer.
