Module 5: Communication Principles

Rory is studying the fields inside an Ethernet frame for an upcoming test and notices that the destination Media Access Control (MAC) address is listed first before the source MAC address. Which of the following protocol characteristics is Rory investigating?

Encapsulation

As Rory continues to study Ethernet, he discovers that a frame can typically be 64 to 1518 bytes of information that is converted into a series of bits before being sent out on the network. Which two protocol characteristics did Rory learn about for Ethernet?

Encoding and Message size

Which three acronyms/initialisms represent standards organizations?

IANA, IEEE, IETF

Which organization publishes and manages the request for comments (RFC) documents?

IETF

Which protocol is used by routers to forward messages?

IP

Bianka, a Polish traveler in Hanoi, Vietnam, stops and asks Nguyệt for directions to the Ngoc Son Temple. They verbally communicate and determine that they both speak English. After receiving directions in English to the temple, Bianka repeats them to Nguyệt. Nguyệt says, "Yes, that is correct." Select the order of the communications protocols used in this scenario?

Method, language, confirmation

IP addressing occurs at what layer of the OSI Model?

Network

Which two layers of the OSI model maps directly as the single network access layer in the TCP/IP model?

Physical and Data link

Which two OSI model layers have the same functionality as a single layer of the TCP/IP model?

Physical and data link

What networking term describes a particular set of rules at one layer that govern communication at that layer?

Protocol

The rules that govern network communications including the message format, message size, timing, and encapsulation, are known as network:

Protocols

What is the purpose of protocols in data communications?

Providing the rules required for a specific type of communication to occur

The IETF (Internet Engineering Task Force) records and publishes internet standards in documents known as:

Request for Comments (RFC)

Which three layers of the OSI model make up the application layer of the TCP/IP model?

Session, Presentation, and Application

Which term refers to the set of rules that define how a network operates?

Standard

Which protocol is responsible for guaranteeing reliable delivery?

TCP

Which statement is correct about network protocols?

They define how messages are exchanged between the source and the destination

Which layer of the OSI model defines services to segment and reassemble data for individual communications between end devices?

Transport

T or F: The 4 layers of the TCP Model are Application, Transport, Internet, and Network Access

True

What is the purpose of the OSI physical layer?

transmitting bits across the local media
