What is the process of converting information into the proper form for transmission?

Encoding

Which step of the communication process is concerned with properly identifying the address of the sender and receiver?

Formatting

Which three are components of message timing?

Flow control, access method, response timeout

Which delivery method is used to transmit information to one or more end devices, but not all devices on the network?

Multicast

BGP and OSPF are examples of which type of protocol?

Routing

Which two protocols are service protocols?

DNS, DHCP

What is the purpose of the sequencing function in the network communication

to uniquely label transmitted segments of data for proper reassembly by the receiver

This protocol is responsible for guaranteeing the reliable delivery of information.

TCP

UDP and TCP belong to which layer of the TCP/IP protocol?

Transport

Which two protocols belong in the TCP/IP model application layer?

DNS, DHCP

Which protocol operates at the network access layer of the TCP/IP model?

Ethernet

Which of the following are protocols that provide feedback from the destination host to the source host regarding errors in packet delivery?

ICMPv4, ICMPv6

A device receives a data link frame with data and processes and removes the Ethernet information. What information would be the next to be processed by the receiving device?

ip at the internet layer

Which services are provided by the internet layer of the TCP/IP protocol suite?

Routing protocols, messaging, internet protocol

What is the process of dividing a large data stream into smaller pieces prior to transmission?

Segmentation

What is the PDU associated with the transport layer?

Segment

Which protocol stack layer encapsulates data into frames?

Data link

What is the name of the process of adding protocol information to data as it moves down the protocol stack?

Encapsulation

True or false? Frames exchanged between devices in different IP networks must be forwarded to a default gateway.

True

True or false? The right-most part of an IP address is used to identify the network that a device belongs to.

False

What is used to determine the network portion of an IPv4 address?

subnet mask

Which of the following statements are true regarding network layer and data link layer addresses?

Network layer addresses are logical and data link addresses are expressed as 12 hexadecimal digits, data link layer addresses are physical and network layer addresses are logical, Network layer addresses are either 32 or 128 bits in length

What is the order of the two addresses in the data link frame?

destination MAC, source MAC

True or False? Data Link addresses are physical so they never change in the data link frame from source to destination.

False

Which three acronyms/initialisms represent standards organizations?

IANA, IETF, IEEE

What type of communication will send a message to all devices on a local area network?

Broadcast

In computer communication, what is the purpose of message encoding?

To convert information to the appropriate form for transmission.

Which message delivery option is used when all devices need to receive the same message simultaneously?

broadcast

What are two benefits of using a layered network model?

It assists in protocol design, it prevents technology in one layer from affecting other layers.

What is the purpose of protocols in data communications?

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

Which logical address is used for delivery of data to a remote network?

Destination IP address

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

Protocol data unit

Which two protocols function at the internet layer?

ICMP, IP

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

Transport

Which type of communication will send a message to a group of host destinations simultaneously?

Multicast

What process is used to receive transmitted data and convert it into a readable message?

decoding
