What is multi-threading and how does it affect memory consistency?

Multi-threading allows multiple threads to run concurrently, improving performance. Memory consistency ensures that threads see the same data.

Can you explain the concept of memory consistency models?

Memory consistency models define the rules for how operations on shared data are seen by different threads. Examples include sequential consistency and eventual consistency.

What are some common issues that arise with multi-threading?

Common issues include race conditions, deadlocks, and memory visibility problems, which can lead to unpredictable behavior.

How can I prevent race conditions in my code?

You can prevent race conditions by using synchronization mechanisms like mutexes, semaphores, or by employing atomic operations.

Are there any programming languages that handle multi-threading better than others?

Languages like Java and C# have built-in support for multi-threading, while others like C and C++ require more manual management.
