Motivation o Motivation In certain situations,a single application may be required to perform several similar tasks.Example:a web server Allow a server to service several concurrent requests.Example: an RPC server and Java's RMI systems The OS itself needs to perform some specific tasks in kernel, such as manging devices or interrupt handling.
