Synchronous transmission is a method of data transfer where data is sent in a continuous stream, synchronized with a clock signal. This means that both the sender and receiver operate on the same timing, allowing for efficient and accurate communication. It is commonly used in telecommunications and computer networks to ensure that data packets arrive in the correct order. In this type of transmission, data is grouped into blocks or frames, which are sent at regular intervals. The synchronization helps to minimize errors and allows for higher data rates compared to asynchronous transmission, where data is sent without a shared clock signal.
