e. SCADA (supervisory control and data acquisition) is a control system architecture comprising computers, networked data communications and graphical user interfaces for high-level supervision of machines and processes. It also covers sensors and other devices, such as programmable logic controllers, which interface with process plant or ...
Switch Inc. was established in 2000 by Rob Roy, who is both the CEO and the company's leading inventor and chief engineer. [3] In 2002, Roy acquired a former Enron facility in Nevada through an auction he was the sole attendee of, due to the secretive nature of Enron's fiber plans.
Data acquisition. Data acquisition is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acronyms DAS, DAQ, or DAU, typically convert analog waveforms into digital values ...
A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects.

Process control network. A Process Control Network (PCN) is a communications network layer that is a part of the Industrial Automation networks in Process Industries. This network is used to transmit instructions and data between control and measurement units and Supervisory Control and Data Acquisition (SCADA) equipment.
Data center management is the collection of tasks performed by those responsible for managing ongoing operation of a data center. [1] This includes Business service management and planning for the future. Historically, "data center management" was seen as something performed by employees, with the help of tools collectively called data center ...
The nearby data centers from Apple Inc. and Switch also received incentives. [ 44 ] [ 62 ] Nevada estimates the construction impact at $2.4 billion and the economic impact from the project at $100 billion over two decades ($5 billion/year, of which $353–378 million are wages) yielding $57 million in state and local taxes.
A functional flow block diagram (FFBD) is a multi-tier, time-sequenced, step-by-step flow diagram of a system 's functional flow. [2] The term "functional" in this context is different from its use in functional programming or in mathematics, where pairing "functional" with "flow" would be ambiguous. Here, "functional flow" pertains to the ...
