HOW TO CHOOSE SERIAL COMMUNICATION PROTOCOL PC

Using the same bus makes the data transmission faster. This means that there are advantages to using this interface type. The synchronous serial interface means that the devices both master and slave use a single bus to transmit the data and clock. The different clock signal that the serial devices require, leads to categorizing the synchronization protocols into the synchronous protocol and asynchronous protocol. The next section is going to explain more about the categorization based on the clock signals. On the other hand, serial devices have different clock signals. When the clock is troubled, it can affect the data transmission. The illustration below depicts the simplicity of how serial communication works.įrom the picture, we know that the clock plays an important role in serial communication. It all leads to the cheaper cost of the overall embedded system and makes it suitable for long-range communication. It means that less input-output (I/O) is needed so that less space is required and more cross-talk resistance. The serial communication transmits one bit of data at a time.

– Example: PC to a printer, HDMI, DVI, and PCI – Example: PC to PC, Microcontroller to microcontroller – “N” wire number of ‘n’ bits data transmission The below table will help you to get a better understanding of the differences between the two. Parallel CommunicationĪside from serial communication, we know that there also exists parallel communication to transmit the data. While the half-duplex is in the middle, the full-duplex provides the best performance. In terms of performance level, the simplex mode provides the least performance out of those three. The smartphone or a phone unit is an easy example we can find. To put it simply, it is a two-way communication method simultaneously. The full-duplex mode is a mode when both the transmitter and receiver can send and receive the data simultaneously. The Walkie-Talkies is a simple example of half-duplex mode. On the other hand, if the receiver is sending the data, then the transmitter can only accept it. If the transmitter is sending the data, then the receiver can only accept it. It also can be said that it is a two-way communication method but one activity at a time. This transmission mode allows the transmitter and sender to be active but not at a time. The keyboard and monitor are also examples of the simplex mode. It can be found in the Radio and Television transmission. When the transmitter is sending the data7, the receiver just accepts it. It means that either the receiver or transmitter is active at a time. Based on the transmission modes, the serial communication can be classified as below: 1. The binary means that zero represents 0 volt or a logic LOW while one represents 5 volts or a logic HIGH. Serial communication is a method to send or data one bit at a time in the form of binary pulses. To get more knowledge about it, the article is here meant for you. The most familiar serial communication that we often encounter is the USB connection. In this article, we are trying to explain the serial communication running in our daily life without us being aware.

A protocol consists of a set of rules that ensure a secure and reliable communication process. In the electronic world, communication is done in certain ways. To communicate is to send (transmit) or receive the data (information) between two or more sides. Communication is an activity that everyone does daily.
