TDMA is a method used in digital networks to:

• A. divide the radio frequency into frequency bands
• B. encrypt traffic
• C. divide the radio frequency into time slots
• D. compress data

Answer: (C)

TDMA uses time division to let multiple users share a single radio channel. The available frequency is divided into repeating time slots, and each user is assigned a specific slot in which they can transmit. This synchronization ensures transmissions don’t collide, enabling efficient use of the channel. This approach is different from methods that share by frequency bands (where each user has a separate band) or by code, and it’s not about encrypting data or compressing it. So dividing the radio frequency into time slots is what TDMA does.
