Etymology

The compound "real-time" emerged in the mid-20th century, combining "real" (from Latin realis, meaning "actual") and "time" (Old English tīma). Initially used in computing (1950s), it described systems processing data without delay. The term later expanded to general contexts (e.g., live broadcasts), retaining its core logic of "actual" + "time" to emphasize immediacy.
