What is the purpose of the OSI physical layer?

• controlling access to media

• transmitting bits across the local media

• transmitting bits across the local media

• transmitting bits across the local media

Which statement is correct about network protocols?

• Network protocols define the type of hardware that is used and how it is mounted in racks.

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

• They all function in the network access layer of TCP/IP.

• They all function in the network access layer of TCP/IP.

Which three acronyms/initialisms represent standards organizations? (Choose three.)

• IANA

• TCP/IP

• IEEE

• IETF

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

• duplex

• encapsulation

• error checking

• Protocol

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

• Application Layer

• Network Layer

• Transport Layer

• Data Link Layer

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

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

• standard

• protocol

• model

• domain

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

• messaging

• protocols

• encoding

• signalling

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

• Internet Protocol Standards (IPS)

• Internet Protocol Standards (IPS)

• IETF Standards Documents (ISD)

• Request for Comments (RFC)

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?
