Definition of Parallel Port (PC, Computer)

Connector or parallel port, usually located at the back of the PC. Located in the computer it is always female.

The parallel port has nothing to do with dumb people who want a port. Jokes aside, it is like a plug that computers have and that allows us to send and receive data from a computer. To explain it better, we are going to use the serial port as an example. This is the same as parallel but it sends and receives data from the computer one after the other. Many velocity, but one after another. The parallel port, however, can send data from each of the 8 connections it has to send data. The latter does not mean that it is faster.

As a system communication Between the computer and devices that are outside of it, it is quite old, in fact, modern computers and computers no longer have this built-in port, mainly due to the appearance of USB ports that are not only capable of sending and receiving data, but are also capable of powering certain devices. It is for this and other reasons that the parallel port is hardly used anymore.

The parallel port connectors in detail.

Only in certain fields such as robotic and some very specific fields. It is used to be able to send instructions to devices that do not have drivers. They were used primarily to connect a printer to the computer or PC. The 25 female pins were put into computers. The printers or devices that made use of this port, had a cable with the 25 male pins to to be able to connect them, as well as some nuts to be able to screw the computer so that the cable. We also know it as LPT port or (Line Print terminal). In principle this port is design to be able to connect any devices and it was called parallel port, but people only used it to connect printers, so it was "baptized" with the abbreviation of LPT1 or Printer Terminal Line or printing. Go! As if it were a special plug for printers. The 1 means that there could be more of the same ports on the same computer. LPT1, LPT2 etc. It uses a language to connect with the computer called IEE 1284. It could also be connected to this port; scanners, zip drives storage, another pc, chips of computing with work instructions, etc.

There have been three different types of LPT, physically they were the same and the only thing that varied were the benefits that gave. That is why we have always known it as a 25-pin shape. See photo.
