What type of device is an Express Card module?

An Express Card module is best classified as a peripheral connection device. This type of device is designed to expand the functionality of laptops by providing additional ports and connectivity options. Express Cards are typically used to add features such as USB ports, network connections, or additional storage capabilities, which are integral to enhancing the performance and versatility of computing systems.
