The term "real-time" refers to the immediate display or processing of data as it occurs, without any delay. It means that the system is operating in a continuous and simultaneous manner, providing up-to-date information as soon as new data becomes available. In other words, real-time means happening at the same rate or speed as something else happens; not delayed or postponed. This term is commonly used to describe systems that require immediate response or feedback, such as in control systems, financial transactions, and communication networks.
