A thread is a small set of instructions that can be handled independently by the scheduler. Multithreading is the concept of allowing multiple threads within the execution of a single process, which allows those threads to share resources. Multithreading is a useful and powerful construct within web-server environments, such as rails. For example, multiple threads could be used to handle requests from multiple users simultaneously, while also handling long running tasks in the background. | |||

Thread Safety
A multi-threaded program presents the risk of race conditions, which are situations in which multiple threads rely on the same system state. This is a dangerous situation because if multiple threads access the same state simultaneously, the state could become corrupted. Thread safety avoids race conditions by guaranteeing that multiple threads can run safely, concurrently.
