Publisher's Synopsis
Simultaneous processing (or concurrent processes, parallel activities) is an essential feature of operating systems. This simultaneity can be observed at the hardware level (central processors, channels, peripherals, etc.), from which the software level is established. Its importance lies in the objectives assumed by the functions of an operational operating system, in order to make the most of hardware possibilities, in particular the increase in processing power. This power, which we are constantly striving to increase by various means (hardware/software), is at the root of the overriding objective of achieving optimum response times.
