How do threads communicate in concurrency?

What are the main ways threads communicate in a concurrent environment?

Threads primarily communicate through shared memory, message passing, and synchronization mechanisms like locks.

Can you explain how shared memory works for thread communication?

Shared memory allows multiple threads to access the same memory space, enabling them to read and write data directly.

What are the risks of using shared memory?

The main risks include data races, where two threads access shared data simultaneously, leading to inconsistent results.

How does message passing differ from shared memory?

Message passing involves sending messages between threads, which can help avoid issues like data races by keeping data isolated.
