Assuming you mean the "D" shell connector used for computer "VGA" connections to a monitor.It's aD shell (physical appearance),E size,15 connectors,So it's correctly called a DE15, but is often misnamed "DB15" - which it's not. To lessen confusion, many people just refer to it as the "VGA" connector.The common "DB" naming only applies (correctly) to the larger shell size commonly used for the 25-pin DB-25 connector. The small 9-pin D connector is correctly called DE-9.

A DB-9 connector is a 9-pin connector, approximately 2cm long by 0.75cm wide, with two rows of pins or sockets, a row of 5 and, a row of 4, hence 9 pins total. It is often used in low-speed data communications such as RS-232, and is the connector on personal computers since the IBM PC-AT used for COM ports. There are larger versions with 15 pins, called DB-15 and used for game ports and 10Base5 network AUIs, and 25 pins, called DB-25 and used for earlier COM ports and printer ports among other things.

A printer cable can connect to a serial printer using a 25-pin "RS-232", DB-25 connector, among other things. In many cases, only a few pins of the defined 25 pins are used (e.g., send, receive, common). There are also adapters that convert between the 25-pin connector and, say, RJ-11 phone cord, RJ-45 Cat 5, or even screw terminals for 3-conductor cable, or what-have-you, for connection to the computer (e.g., a DIN-8 in a Mac), or a converter for USB to RS-232. If it is a Male connector on PC it will be 25-pin Serial Port, If it is a female connector (purple colored if latest) it is parallel port, sometimes called Printer Port(LPT) - Naresh , InfoMax
A DB-25 port is a type of connector that has 25 pins arranged in two rows. It was commonly used for serial and parallel interfaces on older computer equipment such as printers, modems, and early networking devices.
