Asynchronous refers to processes that do not occur at the same time or in a synchronized manner. In computing, it often describes tasks that can run independently without waiting for others to complete. For example, when a program sends a request to a server, it can continue executing other tasks while waiting for a response, improving efficiency. In communication, asynchronous interactions allow participants to respond at their convenience. This is common in emails or messaging apps, where individuals can read and reply to messages without needing both parties to be online simultaneously. This flexibility contrasts with synchronous communication, like phone calls or video chats, where real-time interaction is required.
