More About Asynchronous

What does asynchronous mean?

Asynchronous refers to something not occurring at the same time as another thing.

The opposite of asynchronous is synchronous, which means “occurring at the same time” or “simultaneous.” A face-to-face conversation is considered synchronous, because people are communicating in real time, whereas corresponding over email and text message—where the recipient can respond at a later time—is asynchronous.

Example: The server could only download updates for each game asynchronously, one after the other.

Where does asynchronous come from?

Asynchronous is recorded by the mid-1700s. It combines the Greek-based prefix a-, meaning “without, not,” and synchronous, meaning “occurring at the same time.” The word synchronous itself is also from Greek, combining syn- (“together”) and chronos (“time”).

The term asynchronous has specialized applications in several disciplines:

• In computer programming, asynchronous programming refers to a program that can only begin a new task once the preceding operation is completed.
• In education, asynchronous learning is an educational method that allows students to work at their own pace outside the constraints of a traditional classroom. Email and online discussion boards are common tools.
