These cards slot into various ports on a motherboard or laptop. Their purpose is to offer features that are not present otherwise, such as networking, USB, Thunderbolt, and WiFi support. These cards typically fit into a spare PCI or PCIe slot on a desktop motherboard or to a dedicated I/O port on a laptop, and they provide an easy way to upgrade the system without having to switch out the motherboard and CPU.
