| 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. |
