A task is Ada's concept of expressing concurrency within a program. Tasks are
entities that execute in parallel. Each task represents a separate thread of
control and runs independently between the points where it interacts with other
tasks.
Examples of using tasks are applications requiring the use of concurreny:
large and complex systems (which are inherently concurrent), such as avionics
systems, industry controlling systems, robots, spacecrafts, databases, missile
control facilities, and so forth. Additionally, if you wish to exploit multi-
processor hardware, tasks are a suitable means to do so.
In essence, tasks allow you to cope with what is known as multitasking or
multithreading.
From my point of view, the powerful tasking concept incorporated into Ada
adds to the beauty of the language.

Frank
