APCO Police Communications Practice Test

MDT stands for Mobile Data Terminal. Its main role is as a communications device in patrol vehicles that exchanges data with the dispatch CAD system. In many contexts, the unit is described as having little or no local data processing—the heavy processing happens centrally, while the MDT focuses on sending and displaying data. That aligns with what's being tested here: a device whose purpose is to facilitate data communication rather than perform independent processing. The other descriptions would imply local processing, voice-only use, or simply restating the term without clarifying its role, which doesn’t fit the typical definition of an MDT in this setting.
