PCI/PCI-E Add in Cards

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.

Network Cards

Also known as a NIC (Network Interface Card ), these cards connect directly into the motherboard of your computer and feature an external network socket. This enables the computer to connect to a network via a network cable. Traditionally these network cards use the PCI slot on a motherboard, with newer cards using a PCIe interface. Advanced features include two or more network ports for specific applications. Note that network adaptors that convert a USB port into a network interface are also available.
