Editor to share with you what is the difference between asynchronism and synchronization, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

Synchronization is: all operations are done before returning to the user; in this way, the user waits online for too long, giving the user a feeling of being stuck; in this case, the user cannot close the interface, and if it is closed, the migration program is interrupted. Async is: put the user request into the message queue and feedback to the user, the system migration program has been started, you can close the browser.

Synchronization:

The idea of synchronization is that all operations are done before returning to the user. In this way, users wait online for too long, giving users a feeling of stuck (that is, when the system migration is clicked, the interface will not move, but the program is still executing and the feeling of being stuck). In this case, the user cannot close the interface, and if it is closed, the migration program will be interrupted.

Async:

Put the user request into the message queue and feedback to the user, the system migration program has been started, you can close the browser. Then the program slowly writes to the database. This is asynchronism. But the user does not feel stuck and will tell you that your request system has responded. You can close the interface.

Synchronization and asynchronism themselves are relative.

Synchronization is equivalent to when the client sends a request to the server and the client does nothing else while waiting for the server to respond to the request. Return to the client only when the server has finished. In that case, the client needs to wait all the time. Users will be unfriendly to use.

Asynchronism means that when the client sends a request to the server, while waiting for the server to respond, the client can do other things, which saves time and improves efficiency.

There is a reason that asynchrony is good, but some problems need to be solved by synchronization, for example, there are some things we need to get the returned data to operate. These cannot be solved asynchronously.

These are all the contents of this article entitled "what's the difference between asynchronism and synchronization". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
