Multiple serial, gaming, USB, and parallel ports can be established with an I/O controller card. A controller card works as an interface between the motherboard and various components on a computer.

give the difference between serial port and parallel port
RS-232 serial ports, Parallel ports, and PS2 mouse and keyboard ports. These days, all of these functions can be handled by Universal Serial Bus (USB ) connections.
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.
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.

parallel and serial port
Usually serial. Parallel is almost completely gone, and serial is getting replaced by USB.
Parallel ports typically have 25 or 36 pin ports. Serial ports, by contrast, have only 9 pins. Both type of ports have two rows of pins.
There's no limit to the number of serial ports. The maximum number for the traditional ports is 2 (COM1/COM3 and COM2/COM4). Plus you can attach additional serial port adapters to a USB port, up to 127 per controller.
Its Parallel and Serial
Serial ports only allow one device to send and one device to receive at a time, where a parallel port can send and receive data at the same time.
COM ports transfer data using a serial connection as opposed to a parallel connection.
