Synchronous data transmission (also known as synchronous communication) is a type of digital communication method in which two devices communicate using specific characteristics of data transmission. In this technique, bits of data are sent in a steady stream and synchronized by timing signals generated by special hardware or software. Unlike asynchronous communication, which sends data in a random order with no specific timing signals, synchronous communication ensures that data is received in the exact same order as it was sent.
The main benefit of synchronous data transmission is its ability to ensure that data remains uncorrupted and reliable throughout the entire transmission process. This is because data is sent and received at a specific rate determined by the timing signals that are used to synchronize the devices. Additionally, as the transmission rate remains consistent, devices are able to communicate more efficiently and send larger packets of data in a shorter amount of time.
However, synchronous communication does come with certain drawbacks. One of the main problems is its inflexibility and cost – as the timing signals are generated specifically for two communicating devices, it is difficult (and expensive) to establish communication between two different-sized devices. Additionally, the reliance on timing signals can also create delays or disruptions that can severely decrease the effectiveness of the overall communication process.
Overall, synchronous data transmission is essential when it comes to ensuring the reliability of data transmission between two devices. Despite this, it is important to consider the cost, complexity, and potential delays associated with this type of communication before implementing it in a network.
