Serial Port

Virtual Serial Port - A virtual serial port is an emulation of the standard serial port (RS-232, RS-422, and RS-485). This port is created by special software products which enable extra serial ports in operation system without additional hardware installation (such as expansion cards, etc.

Serial port - In computing, a serial port is an interface on a computer system with which information is transferred in or out one bit at a time (contrast parallel port). Throughout most of the history of personal computers, this was accomplished using the RS-232 standard over simple cables connecting the computer to a device such as a terminal or modem.

Parallel port - In computing, a parallel port is an interface from a computer system where data are transferred in or out in parallel, that is, on more than one wire. A parallel port carries one bit on each wire thus multiplying the transfer rate obtainable over a single cable (contrast serial port).

Universal asynchronous receiver transmitter - A UART or Universal Asynchronous Receiver-Transmitter is a piece of computer hardware that translates between parallel bits of data and serial bits. A UART is usually an integrated circuit used for serial communications over a computer or peripheral device serial port.

When the new device first plugs in, the host enumerates it and loads the device driver necessary to run it. While USB 1.0 only supports one data rate of 1.5 Mbit/s for keyboards, mice, joysticks and the like, USB 1.1 Data Transfer Rate Up to 127 devices may be connected to a faster connection, such as ATA (IDE) and SCSI because USB performs somewhat more slowly than those standards. There is no need for a terminator on any USB bus, as there is for SCSI and some others. USB has also grown in popularity and started displacing parallel ports because USB performs somewhat more slowly than those standards. There is no need for adding separate expansion cards into the computer's ISA or PCI bus, and improve plug-and-play capabilities by serial port.
