A port that handles more than one data bit at a time is a parallel port. The most common example is the printerport (LPT) found on most older computers. The port is designed to transmit and receive 8 bits at a time.
Parallel ports are less common on modern computers as the USB port has now replaced it for the majority of applications.
Serial Ports.
Serial ports transmit data one bit at a time, which is why they are becoming obsolete.
A "Hub".
The port that is connected can either be COM1 or COM2 depending on the communication port.
Parallel port devices are those devices which are connected to the computer via parallel ports. An example is Printer which is connected to the parallel port LPTx (Line Printer Terminal) eg: LPT1, LPT2, LPT3. Parallel ports were originally developed by IBM as a way to connect a printer to your PC. When a PC sends data to a printer or other device using a parallel port, it sends 8 bits of data (1 byte) at a time. These 8 bits are transmitted parallel to each other, as opposed to the same eight bits being transmitted serially (all in a single row) through a serial port. The standard parallel port is capable of sending 50 to 100 kilobytes of data per second.Answer-- A parallel port is a type of interface found on computers (personal and otherwise) for connecting various peripherals. It is also known as a printer port or Centronics port. The IEEE 1284 standard defines the bi-directional version of the port.
this mode is related to only port c.the bits of port c can be controlled directly by the microcontroller
RS232 DB9 connectors Receives data serially from Pin No. 2 & Transmits data from Pin No.3.
Serial ports transmit data one bit at a time, which is why they are becoming obsolete.

how can study of programming methods to read data from / write data to a USB port
USB Port
Boy, this is a toughie...I think it's the PARALLEL port, often noted as LPT1. usb
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.

Parallel signals send multiple bits or entire bytes at a time. The parallel port was used mainly for printers.
However, I don't know if a phone transmits it's screen out the mini port?
