differences in serial ports and parallel ports

On the occasion of this post is inspired by the question one of the friends who asked what was the serial port and parallel port, from there I try to share on my friends and my friends who need hopefully what I have to say this could be an additional reference to a friend who read this article.

Port is a tool that can be used to connect computers with other peripherals. Interface that allows a PC to send or receive information to or from external devices, such as printers or modems. Generally consists of a PC serial port, parallel and several USB ports.

A. Serial Port

Serial Port or commonly known in the Indonesian language is the serial port is a port on a personal computer that serves to transmit one bit of information at one time unit. In the serial ports, shipment information does not allow for a lot sekalius. This is because in doing the data transfer, serial port usually works in series, such as COM 1 and COM 2. To use the serial port is now reduced. Use of the serial port has been replaced with USB and Firewire ports. As for the network (networking) function has been replaced with an Ethernet port. Here are some functions which connects between the serial port peripherals (devices) another computer with a motherboard, a liaison between the mouse with the motherboard, a liaison between the modem to the motherboard, and transmits the information in the form of bits of the mainboard to other devices.

B. Parallel Port

Parallel port or commonly known in the Indonesian language is the parallel port is a port on a personal computer that serves as a communication tool computer (motherboard) with external devices that are parallel. In a parallel port, the transfer of information can be done simultaneously so the information is sent more than a serial port. Commonly known as a parallel port printer port or Centronics port. The function of the parallel port is a connector motherboard with the old type of printer, Zip drive, some Scanners, Sound Cards, Web cams, Gamepads, Joystick, EPROM programming, SCSI devices through a parallel to SCSI adapter, an experiment with a TTL of 12 drivers, and External CD-R or CD-RW. In addition, the parallel port is also used as a simple test in the design of electronic equipment.
