The term synchronous in data transfer refers to a communication method where data transmission occurs in real-time, with both sender and recipient being synchronized in time. In synchronous systems, data is sent and received at the same time, allowing for immediate feedback and interaction. However, this requires both parties to maintain a constant connection. Common examples include real-time communication tools like video conferencing or live chat. Understanding synchronous transfers is important for applications where timely exchanges of information are necessary to ensure smooth operations.
