What is a PCI device?

When I run the man lspci command, I get:

 lspci - list all PCI devices

But I don't know what a PCI device is. Can anyone explain?

A PCI device is basically any piece of computer hardware connected to your motherboard. Peripheral Component Interconnect was a standard introduced by Intel in order to easily integrate peripheral devices such as audio cards or video cards into your motherboard. If you look inside your computer a PCI connector is usually identified by a long strip of raised copper connectors- namely the PCI Bus.

The command lspci lists all the pci hardware connected to your computer- from audio cards to video cards, network cards and so on and so forth.
