A serial port is a 9 pin, RS-232 connection usually used for Terminal connections and older modems as well as some mice and older keyboards for example.
It has lost much of it's popularity and is uncommon on modern computers, usually must be emulated via USB or another port. Usually it's low speed with a asynchronous connection.
A parallel port is usually a 25 pin connection used primarily for printers, some times external devices such as Hard drives or CD-ROM drives, even scanners and modems. It is able to send more then one bit at a time. It is also becoming more obsolete and is less and less common on modern computers.
Hope that helps.

∙ 13y agoA serial port is usually a nine pin device that can send information only one way at a time and usually used for low bandwidth devices like terminal connections or mice or keyboards.
A parallel port is a port capable of asynchronous communication at a higher rate of speed. Typically used for printers or scanners. Some times older external devices like CD-ROM drives or Hard Drives.

What are the examples of serial and parallel ports?
give the difference between serial port and parallel port
Is VGA port a serial port?
No. VGA port is not either serial or parallel port. It is a different interface. If you need a serial output, you need a VGA to serial converter.
Do monitors use a serial or parallel port?
Neither. They use a video port, VGA, DVI, HDMI or Displayport.
What is the difference between a serial port and a parallel port?
Parallel ports are easy to program and faster compared to the serial ports. But main disadvantage is it needs more number of transmission lines. Because of this reason parallel ports are not used in long distance communications. Let us know the basic difference between working of parallel port and serial port. In serial ports, there will be two data lines: One transmission and one receive line. To send a data in serial port, it has to be sent one bit after another with some extra bits like start bit, stop bit and parity bit to detect errors. But in parallel port, all the 8 bits of a byte will be sent to the port at a time and a indication will be sent in another line. There will be some data lines, some control and some handshaking lines in parallel port. If three bytes of data 01000101 10011100 10110011 is to be sent to the port, parallel port communication is faster then serial port.
A D shaped 25 pin female on the back of a computer is a?
Parallel port. The male connector is a serial port. Good luck on the A+ exam :P
What is faster serial port or parallel port?
parallel port if you want to know why go to it140 if you know what that is.
Is prn a serial port?
No. Its a parallel port
What replaces the parallel port?
USB port (Universal Serial Bus) replaces the parallel port
Is a s-video port considered serial or parallel?
S-Video is an analog port, not digital, so "serial" and "parallel" terms do not apply to it.
What is PORT name any two PORT?
USB port, serial port, parallel port.
What ports and ports are considered connectivity port?
parallel and serial port
What are the examples of serial and parallel ports?
give the difference between serial port and parallel port
Can a serial port send data over a longer distance than a parallel port?
Usually, because a serial port doesn't have to deal with the problem of signal skew that can jumble the data on a parallel port and gets worse proportional to distance.
Is VGA port a serial port?
No. VGA port is not either serial or parallel port. It is a different interface. If you need a serial output, you need a VGA to serial converter.
What is meant by serial and parallel transmission?
A serial port only allows a single bit of data through at a time. A parallel port allows multiple bits of data through at a time.
What is parallel serial port?
It's kinda like a perpendicular serial port, but instead of intersecting it just kinda lines up.
How do you redirect a serial port to output out of the parallel port?
You don't. If you are wanting to plug something into the serial port, and it is the same size as the parallel port (it isn't a parallel port, it's a different plug for the serial), use an adaptor. I'm in the same problem. I have a laptop and a program that uses com1 and need to redirect serial communication (com1) to a parallel port since the laptop doesn't have a serial port. i have an adapter for parallel to serial connections but need to remap com1. your can redirect lpt1 outputs with mode lpt1=com1 but not the other way round. If the laptop has usb just grab a USB to Serial Adaptor. Am in the same boot. A Point of Sales app need to be connected via a com port for Receipt Printing... The Printer is a ESC/POS Printer but has a Parallel Connection... Works fine under Windows, but not in the POS App. What is needed is some sort of Virtual COM Port to Capture the Outputs and Redirect it the a Physical LPT Port. In doesn't sound hard, yet no ones don't it...
