Writing programs that perform multiple tasks asynchronously can be done in many ways. It is a broad and important tool in software, and the Async/Await language is only one way to do it. Examples:

  - Multiple cores
  - DMA or other dedicated hardware
  - GPU programming
  - Distributed systems (e.g. the CAN network in your car)
  - Threads
  - Interrupts
  - Event loops
  - Coroutines
