What is the difference between serial port and parallel port?
Serial and Parallel ports are connecting devices used for all types of peripherals such as mouse, printer, keyboard, and anything that you care to add to your computer system. With Serial ports, the data is being transferred at a slow rate or one-bit at a time because it only has two data lines: one to send or transmit and the other for receiving the data from another communicating device. The Parallel ports on the other hand is better and faster because unlike with Serial ports that we can compare to a small road, where the cars would have to wait for the others to pass, we could say that the Parallel port is like an interstate road or highway where there are more than one road for transmitting and another two sets for receiving data. Meaning two or more data can be move at the same time instead of doing it one-at-a-time.

What is the difference between serial port and parallel port?
Generally, a serial port is where you usually connect or attach your mouse, modem, and sometimes the printer and a parallel port is where you normally connect your printer. A serial port is a port or an interface that can be used for serial communication in which only 1 bit is transmitted at a time. Most serial ports on personal computers conform to the RS-232C or RS-422 standards. A serial port is a general-purpose interface that can be used for almost any type of device, including modems, mice, and printers [although most printers are connected to a parallel port].
A parallel port is a parallel interface for connecting an external device like for example a printer. Most personal computers have both a parallel port and at least one serial port. The parallel port uses a 25-pin connector [type DB-25] and is used to connect printers, computers and other devices that need relatively high bandwidth.
