What is the primary difference between asynchronous and synchronous transmission?

Understand the Problem

The question is asking for the main distinction between asynchronous and synchronous transmission methods in data communication, with multiple choice answers provided for clarification.

Answer

Synchronous transmission sends data in blocks or frames, asynchronous transmission sends data in characters or bytes.

The primary difference is that synchronous transmission sends data in blocks or frames while asynchronous transmission sends data in characters or bytes.

Answer for screen readers

The primary difference is that synchronous transmission sends data in blocks or frames while asynchronous transmission sends data in characters or bytes.

More Information

Synchronous transmission is often used for high-speed communications and is synchronized by a common clock, while asynchronous transmission is simpler and used for intermittent data transfer, where you don't need continuous streams.

Tips

A common mistake is confusing the data size limits; synchronous is better for large volumes and asynchronous for smaller or irregular data.
