What are the differences between message passing and shared state in programming?

What are the differences between message passing and shared state in programming?

Message passing involves sending messages between processes, while shared state allows processes to access common data.

Can you give me an example of message passing?

Sure! In a chat application, when one user sends a message, it is passed to the server, which then forwards it to the recipient.

And how does shared state work in a web application?

In a web application, shared state can be managed using a database where multiple users can read and write data concurrently.

Which approach is better for scalability?

Message passing is often better for scalability as it decouples processes, making it easier to distribute them across servers.
