Real-time computing (rtc), or reactive computing is the computer science term for hardware and software systems subject to a real-time constraint, for example from event to system response. Real-time programs must guarantee response within specified time constraints, often referred to as deadlines.
Real time definition, the actual time elapsed in the performance of a computation by a computer, the result of the computation being required for the continuation of a physical process.
Real-time, with a hyphen, is an adjective describing something in which results, feedback, or statistical data follow input with no noticeable delay. The word is increasingly spelled realtime, and this may eventually become the standard spelling if people continue to find the adjective useful.

The actual time during which something takes place the computer may partly analyze the data in real time (as it comes in) r.
The actual time in which a physical process under computer study or control occurs. The time required for a computer to solve a problem, measured from the time data are fed in to the time a solution is received.

Real-time or real time describes various operations in computing or other processes that must guarantee response times within a specified time (deadline), usually a relatively short time. A real-time process is generally one that happens in defined time steps of maximum duration and fast enough to affect the environment in which it occurs, such as inputs to a computing system.
