HTTP, TCP, IP, Ethernet

6. What are proprietary protocols?

protocols developed by organizations who have control over their definition and operation

7. Which IEEE standard enables a wireless NIC to connect to a wireless AP that is made by a different manufacturer?

802.11

8. What is an advantage of network devices using open standard protocols?

A client host and a server running different operating systems can successfully exchange data.

9. What is a function of Layer 4 of the OSI model?

to describe the ordered and reliable delivery of data between source and destination

10. Which statement is true about the TCP/IP and OSI models?

The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.

11. What is a benefit of using a layered model for network communications?

fostering competition among device and software vendors by enforcing the compatibility of their products

12. What is the general term that is used to describe a piece of data at any layer of a networking model?

[ads2]

protocol data unit

13. Which PDU format is used when bits are received from the network medium by the NIC of a host?

Frame

14. At which layer of the OSI model would a logical address be encapsulated?

Network layer

15. Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?

Segments are sent from the transport layer to the internet layer.

16. What statement describes the function of the Address Resolution Protocol?

ARP is used to discover the MAC address of any host on the local network.

17. Which address provides a unique host address for data communications at the internet layer?

logical address

18. Which address does a NIC use when deciding whether to accept a frame?

destination MAC address

19. A user sends an HTTP request to a web server on a remote network. During encapsulation for this request, what information is added to the address field of a frame to indicate the destination?

the MAC address of the default gateway

20. If the default gateway is configured incorrectly on the host, what is the impact on communications?

The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks.

21. IEEE -> is a professional organization for those in the electrical engineering and electronics fields. It creates and maintains standards affecting a wide range of industries including telecommunications, and networking.

EIA -> is an international standards and trade organization for electronics organizations. It is best known for its standards related to electrical wiring, connectors, and the 19-inch racks used to mount networking equipment.
