The stock market data updates in real time on the computer screen.

Definition

Noun: 1. (Computer Science) The time it takes for a process under computer control to occur. This refers to the duration of a computational process, often measured to assess system performance. 2. The actual time during which an event or process occurs. This describes a mode of operation where data is received, processed, and delivered/updated almost immediately, with negligible delay.

Usage

The term "real time" is primarily used as a noun, often functioning as a compound modifier before another noun (e.g., real-time data). It describes systems, processes, or information that are delivered, processed, or updated with minimal latency, closely matching the pace of the actual events they represent.

Examples

• The computer system is capable of processing sensor data in real time.
• Real-time communication apps like video chat have become essential.
• The dashboard provides a real-time view of network traffic.
• Information is updated in real time.

Advanced Usage

• "In real time": This is the most common adverbial phrase, meaning "as events are actually happening."
  • We were able to monitor the experiment's results in real time.
• As a compound adjective ("real-time"): When used before a noun, it is typically hyphenated.
  • The company uses real-time analytics to track user behavior.

Variants and Related Words

• Latency (n): The delay before a transfer of data begins following an instruction. Real-time systems aim for very low latency.
• Live (adj): Broadcast, performed, or presented at the time of occurrence. While similar, "live" often implies a human event (a live concert, live TV), whereas "real-time" is more technical and can refer to automated data processing.
