In an airport, two computers in two different terminals will be in communication-based on the requirements below;

The user in terminal 1 and the receiver terminal 2 can operate on different clock frequencies.

The speed of the communication is not a concern; however, the quality of the communication is important.

The terminals are more than 100 meters apart. There is a heavy external electrical noise which would impact and disrupt the communication and cause miscommunication (corrupted message) between terminals

4a) What would be your preferred data transmission technique? Synchronous or Asynchronous transmission. Explain your answer

4b) What kind of Error Detection method you would use to make sure you will detect most of the communication errors? Explain your answer
