Time Division Multiple Access (TDMA) is a channel access method used in shared medium networks, where multiple users share the same frequency channel by dividing the signal into different time slots. This method increases efficiency by allowing multiple users to transmit data over the same frequency without interference, as each user has a unique time slot for transmission.
Half duplex is a communication method where data transmission occurs in both directions, but not simultaneously, allowing only one party to send information at a time. This approach is commonly used in walkie-talkies and two-way radios, where each party must take turns speaking and listening.
