# What is the difference between Synchronous and Asynchronous?

**Synchronous** means 'ordered communication'. When we do synchronous operation everything that comes later has to wait for the operation to finish before they can start.\
**Asynchronous** means 'unordered communication. Asynchronous is usually used to describe communications in which data can be transmitted intermittently rather than in a steady stream.

**For ex:** a telephone conversation is asynchronous because both parties can talk whenever they like. In synchronous communication each party would be required to wait a specified interval before speaking.
