One of the most powerful features of the Amiga operating system is its
ability to run and manage multiple independent program tasks, providing
each task with processor time based on their priority and activity. These
tasks include system device drivers, background utilities, and user
interface environments, as well as normal application programs. This
multitasking capability is provided by the Exec library's management of
task creation, termination, scheduling, event signals, traps, exceptions,
and mutual exclusion.

This chapter deals with Exec on a lower level than most applications
programmers need and assumes you are already familiar with the Exec basics
discussed in the "Introduction to Exec" chapter of this manual.
