Python core Framework Tornado 2 ways of asynchronous co-processes

What is async?

Meaning: The two sides do not need a common clock, that is, the receiver does not know when the sender is sent, so in the message sent will be prompted to receive information, such as Start bit, and at the end of the stop bit

Phenomenon: There is no common clock, do not consider the order to deal with

Intuitive feeling: It is not necessary to wait, high efficiency

Synchronous

Meaning: Refers to two or more than two times the amount of change in the process of maintaining a certain relative relationship

Phenomenon: There is a common clock, which is processed in the order of one

Intuitive feeling: Just need to wait, inefficient
