It is therefore, many integrated circuits utilize the serial buses when the importance of speed does not exist. The cost of integrated circuits are a lot because of the large number of pins. Improved technology to ensure the integrity of signal as well as increased transmission and receiving speed of data per channel has made the serial ports a close competitor to parallel ports. 1 – Serial Communication – Data Flow through Single PathĪt small distances, serial buses are becoming more common and popular because the disadvantages of parallel buses prevails their advantage of simplicity. As the cost of establishing a parallel communication is very high and its configuration is lengthy and complex, the Serial communication is preferred for all major communication/computer networks.įig.
Hence, for a two-way digital communication, we will only need two wires between the transmitter and receiver. Serial communication takes place by using only a single wire or line. This is directly opposite to the function of parallel communication, where several bits are sent together on a bus consisting of many wired lanes in parallel. How does an arrow shoots from the bow? One at a time, isn’t it? Same is the case with Serial Communication. Serial communication can be defined as the method of sending one bit of data at one point of time in succession through a bus. This post will discuss Serial Communication, its protocols, comparison of RS Standards and advantages of Serial Communication over Parallel Communication. It became popular owing to its low cost installation and less space requirements. Serial Communication is the simplest communication of all between a sender and receiver.
