"SERDES" (Serializer Deserializer) is a global statement of a circuit function. - Generally means take parallel data, convert to serial data, send it over a transmission medium (ofter wires, but not always) and receive it and process back to parallel data.

Many devices (some of what you mention) use SerDes structures, USB1,2,3, Ethernet, Firewire (and many others) have SerDes structures within them. However, they differ in data rates, encoding, compensation methods, etc, etc.
