What is the purpose of geocoding in an address system?

• A. To convert coordinates to addresses
• B. To convert an address to geographic coordinates for mapping and proximity searches
• C. To validate email addresses
• D. To hash addresses for anonymity

Answer: (B)

Geocoding is the process of turning a human-readable street address into precise geographic coordinates (latitude and longitude). This translation lets a system place the location on a map, perform distance calculations, and support proximity searches or routing. It enables mapping and spatial queries by converting the address into a form that can be spatially analyzed. The other options describe tasks that aren’t about locating an address on a map—converting coordinates back to an address is reverse geocoding, validating emails is unrelated to geography, and hashing addresses is a privacy measure, not a locating task.
