Activity

Dear Students, please copy the following questions in the paper of your own and write in with the correct answer.

1.	Describe how lack of synchronization between a transmitter and a receiver can cause communication errors.

2.	Outline three methods to implement synchronous transmission.

3.	Asynchronous transmission divides bits to be transmitted into small blocks. Explain why.

4.	Why synchronous transmission is more efficient than asynchronous transmission when transmitting large data blocks.

5.	What is the different between half duplex and full duplex communication channels.

6.	What is the role of a DCE in communicating data between a sender and a receiver.

7.	Describe how an RS-232 interface between a DTE and a DCE support the limited distance modem communication scenario.

8.	Describe the use of the Null Modem communication setup.
