- A.
In-car Global Positioning System (GPS) receivers send signals to satellites, which calculate the car’s location and send it back.
- B.
HTTP stands for HyperText Transfer Policy.
- C.
RAM stands for Rapid Access Memory.
- D.
A Geographic Information System (GIS) is a computer-based tool for mapping and analysing features and events on Earth.
Show answer & explanation
Correct answer: D
Concept
ICT statements can be tested by matching each acronym with its standard expansion and each system with its actual data flow or function.
GPS receivers compute position from satellite broadcasts; HTTP is the Hypertext Transfer Protocol; RAM is Random Access Memory; and GIS handles spatially referenced information.
Application
The description of GIS as a computer-based tool for mapping and analysing features and events on Earth matches its standard function.
Contrast
GPS satellites broadcast timed signals; the receiver in the car combines signals from multiple satellites to compute its own location.
The final word in HTTP is Protocol, not Policy.
The first word in RAM is Random, not Rapid.
GIS integrates spatial data with computer-based mapping and analysis.
Cross-check
Expanding the acronyms and tracing the GPS signal direction leaves the GIS description as the only statement consistent with standard ICT terminology and operation.
Therefore, the statement defining GIS as a computer-based mapping and analysis tool is the answer.
