db is one of the computer connector that transfer information to other devices
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.
The most common Serial porty is the DB port also know as D-sub or D-subminiature port. USB is not serial port.
If you need to access a database with Java, you need a driver. This is a list of the drivers available, what database they can access, who makes it, and how to contact them.

1.16What is a characteristic of an RSTP edge port?
This is a 25 pin cable, usually used to connect a printer to your computer (parallel port). Most printers connect using the USB cable anymore, as other external devices.
LPT is short for Line Printer. So it is a parallel port. The most common type of socket is a DB-25.
some kind of port also called a i/o port for input/output on the computer
its a 15 pin female port, which is blue in color. VGA is used to connect monitors. It is also known as DB 15
I don't think your computer has a PS2 port or that you PS2 has ports that do not have proper names Like USB Port or Ethernet Port
I've seen DB-25s used for parallel ports (fairly common), serial ports (sometimes, though a DB-9 is more typical), and very occasionally on antique hardware, SCSI ports. I can't think of any time I've seen them used for any other kind of port.
