What are some real-world examples of concurrency?

Concurrency refers to the ability of a system to handle multiple tasks simultaneously. Some real-world examples include web servers handling multiple requests, operating systems managing multiple processes, and databases allowing multiple transactions at once.

Can you explain how web servers use concurrency?

Sure! Web servers use concurrency to manage multiple client requests at the same time. They can do this through techniques like multi-threading, where each request is handled in a separate thread, or by using asynchronous I/O, allowing the server to process other requests while waiting for data.

What about concurrency in databases?

In databases, concurrency allows multiple users to access and modify data simultaneously. This is managed through locking mechanisms and transaction isolation levels to ensure data integrity and prevent conflicts.

Are there any programming languages that support concurrency better than others?

Yes, some programming languages have built-in support for concurrency. For example, Go has goroutines, which make concurrent programming easier, while Java has the Executor framework for managing threads.
