Final answer:
A Mobile Data Terminal (MDT) exchanges information using a wireless network. This allows for digital communication between an end user and a communication center, making use of digital data transmission in the form of binary ones and zeros.
Step-by-step explanation:
A Mobile Data Terminal (MDT) is used in communication systems to exchange information between an end user, such as a public service vehicle, and a communications center. It utilizes a wireless network to facilitate this exchange. Given that cell phones use a radio receiver and a weak radio transmitter that can quickly tune to hundreds of specified microwave frequencies within a ground-based cell system and require a clear line of sight, MDTs similarly interact within a wireless network framework. Especially noteworthy, is that communications like mobile data and calls, or transmission of images and videos, are frequently sent as digital data. This digital form comprising binary ones and zeros, known as bits, ensures that data can be transmitted more clearly and efficiently.
