What is Multi thread programming?

Multi-threaded programming is a concurrent programming model where multiple threads of execution run within a single process. These threads share the same process resources, such as memory space, but execute independently. This allows for improved performance by enabling parallel execution of tasks, especially on multi-core processors. It's commonly used to improve responsiveness of applications by offloading long running tasks to background threads, and to take advantage of parallelism to speed up computation-intensive tasks. Issues like race conditions and deadlocks need to be addressed when designing multi-threaded applications.
