What does a supervisory control and data acquisition (SCADA) system manage?

1. Small-scale applications

2. Mobile devices

3. Large-scale, geographically distributed devices

4. Home networks

The correct answer is: Large-scale, geographically distributed devices

A supervisory control and data acquisition (SCADA) system is specifically designed to manage and control large-scale, geographically dispersed devices and processes in various industries. These systems are integral in sectors such as utilities, manufacturing, and infrastructure, where they gather real-time data from remote locations and allow operators to monitor and control these systems remotely. SCADA systems are equipped to handle complex networks of sensors, control equipment (like valves and pumps), and data communication infrastructure. They enable centralized control over activities that can span vast areas, such as power generation and distribution plants, water treatment facilities, and transportation systems. This capability is essential for operational efficiency, safety, and handling emergency responses. In contrast, the other options refer to more localized or smaller-scale technology systems. Small-scale applications do not require the extensive functionality of SCADA, mobile devices often center on personal and portable computing needs rather than industrial control, and home networks typically involve simpler networking setups without the robust management features characteristic of SCADA systems. Thus, the effectiveness and design of SCADA systems make them particularly suited to large-scale applications.
