The
DB9 is also known as 9-
pin D-sub, DE-9 (its correct name), DB-9, serial
connector, RS232
connector or null modem
connector.

RS232 is the definition of the serial interface, e.g. the signal voltage and duration. DB9 is the 9 pin connector. But of course you can solder the cable to the devices directly also, without a DB9 or DB25 connector.
The current version of the standard is TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange, issued in 1997. The RS-232 standard had been commonly used in computer serial ports and is still widely used in industrial communication devices.
The Aston Martin DB9 is a British grand tourer first shown by Aston Martin at the 2003 Frankfurt Auto Show. Available both in coupé and a convertible bodystyles, the latter being known as the Volante, the DB9 was the successor of the DB7. It was the first model built at Aston Martin's Gaydon facility.
A standard DisplayPort cable is designed to work with any DisplayPort Source device, such as a PC or laptop, and any DisplayPort monitor. You can also use a standard DisplayPort cable between a PC and a multi-stream hub, or between daisy-chainable multi-stream monitors.
DisplayPort (DP) was designed to replace VGA, DVI, and FPD-Link and standardized by VESA. It is primarily used to connect a video source to a display device such as a computer monitor.
No it will not work with a VGA monitor. If it is specifically marked as RS-232 (or with a string of one's and zero's), then it is a serial port for things like serial mice.
The connector on the graphics card and monitor is HD15, which is 15 pins in 3 rows, and is called a VGA connector for historical reasons. It's a totally different connector, and isn't “serial” at all, as the colour data is actually transmitted in parallel alongside the H and V sync signals.
On a modern PC, a DB-25 (especially a female connector) is typically associated with a parallel (aka LPT) port. On older computer and telecommunication equipment, a DB-25 connector is typically a RS-232 serial port. Prior to the mid-1980s, RS-232 ports typically used DB-25 connectors.
DVI was purposely developed and designed to transmit video signals. In comparison, the D-sub connector is used for a much wider variety of applications. DVI is capable of transmitting both analog and digital signals its D-sub equivalent (the DE9) only carries analog signals.
D-Sub refers to a "digital sub-miniature" cable connection. The VGA D-Sub cable uses a D-shaped connector containing 15 pins.
Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor.
By signal standard
| Signal standard name | Introduction year | Connector |

| High-Definition Multimedia Interface (HDMI) | 2003 | 19 pin HDMI Type A/C |
| DisplayPort | 2007 | 20-pin (external) 32-pin (internal) |
| DiiVA | 2008 | 13-pin |
| HDBaseT | 2010 | 8P8C |
The DB25 (originally DE-25) connector is an analog 25-pin plug of the D-Subminiature connector family (D-Sub or Sub-D). As with the DB9 connector, the DB25 is mainly used for serial connections, allowing for the asynchronous transmission of data as provided by standard RS-232 (RS-232C).
The main difference between a serial port and a parallel port is that a serial port transmits data one bit after another, while a parallel port transmits all 8 bits of a byte in parallel. Computers have both serial and parallel ports along with newer technology called a USB (Universal Serial Bus) port.
The HD15 is a High Density DB-style connector, so it can also be called an HD DB15. Another popular name is "VGA connector", although it is used in video applications that support much higher resolutions (SVGA, XGA, UXGA, etc.).
DisplayPort (DP) is an audio/video (A/V) display interface used to connect a video source to a display device. For example, you may connect a computer monitor to the PC using the DisplayPort.
The DB25 (originally DE-25) connector is an analog 25-pin plug of the D-Subminiature connector family (D-Sub or Sub-D). Like the DB9 connector, the DB25 is primarily used for serial connections, allowing asynchronous transmission of data provided by standard RS-232 (RS-232C).
CAN-Bus Data Cable reduces wiring, electronic interference, and offers high-speed network communication. It is resistant to abrasions and cuts, while also has an excellent resistance to oil and chemicals. The SAE J1939/15 is unshielded with no drain and the SAE J1939/11 CAN-Bus Cable is shielded with drain wire.
