Modes of Data Transfer in Serial Communication: Parallel communication- you are shooting a target using a shotgun, where many number of the bullets reach at the same time. Serial communication – you are shooting a target using machine guns, where bullets reach one by one to the target. Serial communication is slower than parallel communication but used for long data transmission due to lower cost and practical reasons.
While in parallel communication the data is transmitted in a byte (8 bit) or character on several data lines or buses at a time. In telecommunication, the process of sending data sequentially over a computer bus is called as serial communication, which means the data will be transmitted bit by bit. you can check them out if interested. In this article, we will understand the basics of the RS232 Protocol and how it works. Today there are many modern communication protocols like the RS485, SPI, I2C, CAN etc. It was introduced back in the 1960s and has found its way into many applications like computer printers, factory automation devices etc.
The term RS232 stands for "Recommended Standard 232" and it is a type of serial communication used for transmission of data normally in medium distances. One of the oldest, yet popular communication protocol that is used in industries and commercial products is the RS232 Communication Protocol.
