A five-pin row sits above a four-pin row in the arrangement of DB-9 pins, which are organized in rows of two.
The EIA/TIA 232 serial interface standard established the purpose of each of the nine pins as a standard so that different manufacturers may incorporate them into their products. DB9 connections are made to work with this standard. Keyboards, mouse, joysticks, and other serial peripheral devices were frequently connected using these connectors. For data communication, they are also utilized in DB9 cable assemblies.
Today, more advanced interfaces like USB, PS/2, Firewire, and others have mostly taken the place of the DB9. However, the DB9 interface is still widely used by many vintage devices for serial communication.
