Data Exchange

1. Transmission Modes

   • Simplex - This is data transmitted in one direction only.
   • Half Duplex - When devices can communicate with each other, but only one at a time.
   • Full Duplex - When devices can communicate with each other at the same time.

2. VOIP (voice over internet protocol), so we can hear each other when communicating. It works by coding the original message into binary 0 and 1's. The recieving computer then decodes the 0 and1's back into analog.

3. Parallel Transmission - Transmits data eight bits at a time.

4. Series Transmission - Transmits data one bit at a time.
