- access control
- flow control
2. What is done to an IP packet before it is transmitted over the physical medium?
- It is tagged with information guaranteeing reliable delivery.
- It is segmented into smaller individual pieces.
- It is encapsulated into a TCP segment.
- It is encapsulated in a Layer 2 frame.
3. What process is used to place one message inside another message for transfer from the source to the destination?
- access control
- flow control
4. A web client is sending a request for a webpage to a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to prepare the request for transmission?
- HTTP, IP, TCP, Ethernet
- HTTP, TCP, IP, Ethernet
- Ethernet, TCP, IP, HTTP
- Ethernet, IP, TCP, HTTP
5. What are two benefits of using a layered network model? (Choose two.)
- It assists in protocol design.
- It speeds up packet delivery.
- It prevents designers from creating their own model.
- It prevents technology in one layer from affecting other layers.
- It ensures a device at one layer can function at the next higher layer.
6. What is the purpose of protocols in data communications?
- specifying the bandwidth of the channel or medium for each type of communication
- specifying the device operating systems that will support the communication
- providing the rules required for a specific type of communication to occur
- dictating the content of the message sent during communication
7. Which logical address is used for delivery of data to a remote network?

12. Which three acronyms/initialisms represent standards organizations? (Choose three.)
13. What type of communication will send a message to all devices on a local area network?
14. In computer communication, what is the purpose of message encoding?
- to convert information to the appropriate form for transmission
