Serial connections were mainly used before PS/2 connectors were invented but are still sometimes used today to connect routers and switches and firewalls. This connector is either a DB9 or DB25. They are usage specific which is determined according to their pin connection and wiring configuration Audio connectors and cabling is pretty standard. They are used for sound input/output and can be found on a host of different devices including speakers and headphones.
