There are two types of serial communications Asynchronous and synchronous transfer (refer to the article “ differences between asynchronous and synchronous transmission” for more info). Since it uses only two channels to complete a full-duplex communication, it is far more efficient for communication over long distances with very little installation cost. It is very simple to implement, and the data is less affected by interference. The serial communication is a better choice for long-distance communication because it uses a single channel which requires fewer wires and accommodates very little space. Therefore the serial communication is relatively slower. Since there is only one channel, the serial communication cannot send the whole byte at once, instead, the 8-bits are sent one by one in series. Serial communication is a type of digital communication where the data is transmitted bit by bit through a common channel.

Therefore the digital signal can be sent bit by bit in a sequence or we can send the whole byte at a time. The binary data exists in the form of bytes where each byte is made of 8 individual bits. The binary signal or data exists in the form of bits whose amplitude is either only “0” or “1” corresponding to ground “0” and supply voltage. The digital signal can have multiple discrete values but when they are represented using only two possible values of amplitude they are called a binary signal. Therefore digital communication only uses a wired medium for the transfer of data. The digital signal cannot be transmitted through a wireless medium. The digital signal is a signal having discrete amplitude values. Digital Communication:ĭigital Communication is a type of communication where a digital signal is transferred between two devices through a medium. it can be transmitted through wired communication or wireless communication.
The Analog signal is a variable signal having continuous amplitude and continuous time. The analog communication is a type of communication where an analog signal is transferred between two devices through a medium. Related Post: Difference between Analog and Digital Circuit – Digital vs AnalogĬommunication is mainly classified into two main types Analog and Digital communication.It is the most common mode of communication being used in the Telecommunication engineering world. It uses two individual channels for sending and receiving the signal. For example walkie-talkieįull Duplex Communication: It is a two-way communication where the information or signal can travel in both directions at the same time. It can either send the signal or receive the signal at a time. Half Duplex communication: It is a two-way communication using a single channel but the information can travel in only one direction at a time. The receiver cannot transmit back the signal. The sender sends the signal and the receiver receives it using a single channel. Simplex communication: it is a one-way communication that allows the transfer of information in only one direction. The communication can be classified into simplex, half-duplex and full-duplex modes of transmission. The medium used for the transfer of signal could be a wire (for wired communication) or radio signals (for wireless communication). The information being sent could be an audio, video, or any other encoded data. In Electrical and Electronics engineering, communication means the exchange of any kind of information in the form of the electrical signal between two devices through a transmission medium. Main Differences between Serial and Parallel CommunicationĬommunication is the process of exchange of any useful information between two participants.
