A video port has 15 pins (3 rows of 5 each) A video port, also known as a Serial Port, has 3 rows of 5 pins which is 15 pins.
The PIC16F88 microcontroller has a total of 13 I/O pins that can be configured as user input or output ports. These pins are grouped into Port A, Port B, and Port C, with Port A having 6 pins, Port B having 8 pins, and Port C having 4 pins. However, the exact number of usable I/O pins can depend on the specific configuration and function requirements of the application.
A male port has pins, onto which a unit, which has holes, fits. A female port is more common, where there holes into which pins are inserted, like the video port, keyboard port or mouse port on the back of your PC.
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
There are four pins in a USB port. The positive, negative and Data positive, data negative.
