What is the use of serial communication port?
A socket that connects to a serial interface (one bit following another over one line). Serial ports are widely used by sensors for data acquisition, and they were standard on early computers for connecting a modem, mouse and other peripherals. Old Macs used the serial port for printers.
Why is serial communication needed?
The main advantage of serial communication is, the cost of the entire embedded system becomes cheap and transmits the information over a long distance. Serial transfer is used in DCE (Data communication Equipment) devices like a modem. So, each bit of data requires a separate physical I/O line.
What are serial communication ports?
In computing, a serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. This is in contrast to a parallel port, which communicates multiple bits simultaneously in parallel.
Do I need a serial port adapter?
If you need to connect a serial device to your computer but your computer doesn’t have a serial port, then you need a USB to Serial adapter. Finding the best adapter can be a challenge since there are so many differnt models, types and manufacturers.
Is a serial port the same as a VGA?
In summary, no, a serial port is not a video port and there is no way to use a monitor of any kind with it (even a 9-pin monitor, let alone 15-pin one). Since it does not have onboard video, you will need to install a video-card.
