Each program we have seen so far has been a sequential, or
single-threaded, one; that is, it has consisted of a series of steps that are executed in
sequence, one after the other. In this chapter, we introduce the idea of a concurrent, or
multithreaded, program, one in which several things can happen--or at least appear to
happen--simultaneously.
Concurrent actions are really part of most interesting programs. For
example, a time-shared operating system must deal with a number of human users working
simultaneously at their terminals. Further, many real-time applications, especially those
controlling physical processes, are composed of concurrent program segments, each
responsible for its own physical subsystem. Finally, the world is concurrent, filled with
people doing different things all at the same time, and a program that would model that
world is best seen as comprising concurrent program segments.
List:
- Somebody - some@some.ru
- Somebody - some@some.ru
- Somebody - some@some.ru
- Somebody - some@some.ru
An Ada task is an interesting structure. It has aspects of a package, of a
procedure, and of a data structure, but is really none of these; it is something different
altogether.
