1. Transmission Modes

   • Simplex- Data is only transmitted in one direction only.
   • Half Duplex- This is where devices can communicate with each other but only one at a time, like walkie-talkies.
   • Full Duplex- This data channel allows two-way communication, like a phone conversation or a video call on Skype.

2. Parallel and Serial Transmission

   • Serial- Transmits data 1 bit at a time.
   • Parallel- Transmits data 8 bits at a time.
