Therefore, for this reason, transmission lines are preferred to be short in parallel communication. To eliminate crosstalk and errors, all bitstreams need to transfer data at the same speed in parallel communication.
Unlike serial port, It uses a 25 pin connector that is called DB-25 connector. That’s why it is faster in comparison to the serial communication. Unlike serial port, a parallel port can move a set of 8 bits at a time on eight different wires. DB-9 pin connector diagram is given below. Serial ports are typically implemented in the modems, connecting devices, controllers, mouse and also in security cameras. The transmission speed of serial port is comparatively low as compared to parallel port transmission speed. The length of the wire can be increased as needed. Therefore, like parallel transmission, in serial transmission data speed mismatch is not a problem. Serial communication gained by single wire and only the single stream of data is transferred from one end to other. These ports can dock a 9-pin D-shaped connector that connects to the transmission line, is called DB-9 connectors. Prerequisite – Introduction of Ports in ComputersĪ serial port is an interface that is used for connecting the serial lines to attain the serial communication.
