Asynchronous running, also known as parallel computing, is a type of computer programming that allows multiple tasks to run simultaneously. Its synonyms include concurrent execution, multicore processing, and parallelism. Additionally, the term multithreading is often used interchangeably with asynchronous running, as it refers to a way of breaking down larger tasks into smaller threads that can be executed simultaneously. Asynchronous running is especially important for improving the performance of complex, resource-intensive programs like video editing or data analysis. While it requires specialized knowledge and tools to implement properly, it can significantly increase the speed and efficiency of these types of applications, resulting in faster processing times and improved user experiences.
