Computer Hardware Terms, Glossary and Dictionary

Database Bus connector (DB connector), defined by various EIA/TIA standards, is a type of connectors used to connect serial and parallel cables to a data bus. DB connector names are in the format of DB-x, where x represents the number of (wires) within the connector. Each line is connected to a pin on the connector, but in many cases, not all pins are assigned a function. DB connectors come in 9, 15, 25, 37 and 50-pin sizes. The DB connector defines the physical structure of the connector, not the purpose of each line. For example, DB-9 connectors have 9 pins and are used to connect a mouse. DB-25 connectors have 25 pins and are used to connect a printer.
