Explain why data acquisition must be accurate and timely in SCADA systems.

Accurate and timely data ensures correct decisions and control actions, preventing errors and improving safety and efficiency.

What does data acquisition in SCADA primarily capture?

A Network traffic data

B Real-world measurements from sensors

C Software error logs

D User login information

Data acquisition focuses on collecting real-world measurements like temperature and pressure from sensors.

Why is real-time data important in SCADA systems?

A To make timely control decisions

B To store historical data only

C To update software versions

D To manage user accounts

Real-time data allows SCADA to respond quickly to changes and control processes effectively.

Which device is NOT typically used for capturing real-world measurements?

A Keyboard

B Temperature sensor

C Pressure gauge

D Flow meter

Keyboards are input devices for users, not for capturing physical measurements.

How does data acquisition help in system safety?

A By disabling alarms

B By ignoring sensor data

C By delaying data collection

D By detecting abnormal conditions early

Early detection of abnormal data helps prevent accidents and system failures.

What happens if data acquisition is inaccurate?

A User interface improves

B System runs faster

C SCADA makes wrong decisions

D Network speed increases

Inaccurate data leads to wrong control actions, risking safety and efficiency.
