Tests for voltage input thresholds can be used to make important distinctions about the characteristics of a device during validation, as well as the quality of a device during production test.
Process-oriented programming is a programming paradigm that separates the concerns of data structures and the concurrent processes that act upon them.
In UNIX and some other operating systems, a process is started when a program is initiated (either by a user entering a shell command or by another program). Like a task, a process is a running program with which a particular set of data is associated so that the process can be kept track of. An application that is being shared by multiple users will generally have one process at some stage of execution for each user.
