In systems that control processes, data is continuously transmitted along a data highway, ensuring real-time communication and efficient data flow between devices or computers involved in the process control.
18. A(n) ____ is composed of several computers connected together to share resources and data.
A network is composed of several computers connected together to share resources, data, and services. It allows communication and resource sharing between devices, whether locally (LAN) or over long distances (WAN).
19. A datum that indicates some important state in the content of input or output is
A sentinel is a special datum used to mark significant states in the content of input or output, often indicating boundaries, like the end of a data stream or a specific condition.
