Works like USB buses but at higher speeds.

HPSB (High Performance Serial Bus) ports:

Supports plug-and-play and hot plugging.

Data rate speed varies from 10 MBPS - 1000 MBPS depending upon the type of port used like 10BaseT - 10 MBPS, 100BaseT - 100 MBPS and Giga Ethernet - 1000 MBPS.

Most computer and laptop includes one built-in Ethernet port for connecting to a wired Local Area Network (LAN).

Sends 8 bit data simultaneously over 8 pins.

Open(Comm Port,BauRate,DataBit,Parity,StopBit,DataStopBit,BufferSize) : Opens. Declare necessary Rs232 class variables for make communication with the Comm Port possible.

To connect external devices that sends lot of data over a short distance. That is, SerialPort class represents a serial port resource.

Mouse, keyboard and video uses serial ports.

Several hardware ports are available at backside of the cabinet like keyboard, mouse, monitor, printer, modem etc.

Software ports are virtual or logical connection needed to exchange information between the programs.Hardware ports are usually male or female type.Ports are connecting sockets, used to connect peripheral devices on the system unit.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.

If there is a delay on the Centronics port, the RS232 bitstream from the computer may be stopped via the Flow signal (pin 17). The IC also generates the requisite control signals. This is essentially a programmed PIC controller that produces a Centronics compatible signal from a 2400 baud serial signal (eight data bits, no parity, one stop bit). The serial-to-parallel conversion is effected by IC1. This is an integrated level converter that transforms the single +5V supply into a symmetrical ☑2V one. Since the computer needs real RS232 levels, an adaptation from TTL to RS232 is provided in the converter by a MAX232. The CTS and DSR signals enable handshaking to be implemented. The TxD line, pin 3, CTS line, pin 8 and the DSR line, pin 6, of the serial port are used – see diagram.

It converts a serial 2400 baud signal into a parallel signal. This converter may help if just the serial port on a personal computer is free, whereas the printer needs a parallel (Centronics) port.
