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.
DB701 is lighter (They are German Railway Colours - Deutsche Bahn = DB)
No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10.

Decibel is abbreviated as "dB."
60 dB: normal conversation 90 dB: lawnmower 120 dB: rock concert 150 dB: fireworks display
80 dB is 10 times louder than 70 dB, and 70 dB is 10 times louder than 60 dB, and so on. Therefore, 80 dB is 1000 times louder than 40 dB.
LPT is short for Line Printer. So it is a parallel port. The most common type of socket is a DB-25.
If it has 15 pins it is NOT a serial port! A serial port will have either 9 pins (DB-9), or 25 pins (DB-25). The 15 pin connector (usually blue) is analog video or VGA, and yes if your graphics card is powerful enough it can run dual monitors. You can either buy a dual port graphics card or a splitter to run dual monitors
DB-25 D-Sub-9 or D-Sub-25
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.
db is one of the computer connector that transfer information to other devices
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.

For Send Mail Transfer protocol default port number as is 25. SMTP actually stands for Simple Mail Transfer Protocol. I agree with the port number
By default it listens on SMTP port 25
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.
Port 25 is reserved for SMTP traffic. Hence, it is listening for email.
