Question 1: segment

Answer:

In TCP, a term used to describe a TCP header and its encapsulated data (also called an L4PDU). Also in TCP, the process of accepting a large chunk of data from the application layer and breaking it into smaller pieces that fit into TCP segments. In Ethernet, a segment is either a single Ethernet cable or a single collision domain (no matter how many cables are used).

Question 2: PDU Layers

Answer:

L7PDU, L6PDU, L5PDU, L4PDU, L3PDU, L2PDU

Question 3: Encapsulation for all Data

Answer:

Frame

Question 4: PDU

Answer:

A generic term from OSI that refers to the data, headers, and trailers about which a particular networking layer is concerned.

Question 5: OSI model 7-1

Answer:

Application, Presentation, Session, Transport, Network, Data Link, Physical

Question 6: Encapsulation for IP is?

Answer:

Packet

Question 7: TCP/IP Model Layers 5-1

Answer:

Application, Transport, Network, Data Link, Physical

Question 8: Adjacent-layer interaction on the same computer

Answer:

On a single computer, one layer provides a service to a higher layer. The software or hardware that implements the higher layer requests that the next lower layer perform the needed function.

Question 9: de-encapsulation

Answer:

The process in which the device interprets the lower-layer headers and, when finished with each header, removes the header, revealing the next-higher-layer PDU.

Question 10: Frame

Answer:

A term referring to a data link header and trailer, plus the data encapsulated between the header and trailer.

Question 11: Encapsulation for TCP is?

Answer:

Segment

Question 12: same-layer interaction

Answer:

The communication between two networking devices for the purposes of the functions defined at a particular layer of a networking model, with that communication happening by using a header defined by that layer of the model. The two devices set values in the header, send the header and encapsulated data, with the receiving devices interpreting the header to decide what action to take.

Question 13: Encapsulation

Answer:

The placement of data from a higher-layer protocol behind the header (and in some cases, between a header and trailer) of the next-lower-layer protocol. For example, an IP packet could be encapsulated in an Ethernet header and trailer before being sent over an Ethernet.

Question 14: Same-layer interaction on different computers

Answer:

The two computers use a protocol to communicate with the same layer on another computer. The Protocol defines a header that communicates what each computer wants to do

Question 15: Packet

Answer:

A logical grouping of bytes that includes the network layer header and encapsulated data, but specifically does not include any headers and trailers below the network layer.

Question 16: Networking Model

Answer:

A generic term referring to any set of protocols and standards collected into a comprehensive grouping that, when followed by the devices in a network, allows all the devices to communicate. Examples include TCP/IP and OSI.
