coroutine
A coroutine is a piece of code that can be paused and resumed. In contrast to threads which are preemptively multitasked by the operating system, coroutines multitask cooperatively. I.e. they choose when to pause (or to use terminology for coroutines before 3.4 - yield) execution. They can also execute other coroutines.
event loop
The event loop is the central execution device to launch execution of coroutines and handle I/O (Network, sub-processes...)
future
It’s like a mailbox where you can subscribe to receive a result when it will be done. More details in official documentation
task
It represents the execution of a coroutine and take care the result in a future. More details in official documentation
