1

Which layer of the OSI model contains all the services or protocols that are needed by application software or the operating system to communicate on the network?

Application

2

The encapsulation unit on the Data Link layer of the OSI Model is _____

Frame

3

Define: Physical layer

all aspects of physically moving data from one computer to the next.

4

_____ are used for node-to-node communications on a network. Logical address, Port address, Physical address, Socket

Physical Address

5

Define: frame

The packet becomes this in the Data Link layer.

6

What is the 7th Layer of the OSI Model?

Application

7

The process of moving data from one layer of the OSI model to the next layer is called

encapsulation

8

The Application layer of the TCP/IP Model corresponds to the blank layer(s) of the OSI model

Session and Presentation

9

Define: frame synchronization

a method of finding valid data in a transmission that consists of data frames

10

The primary job of the Presentation layer concerned with

data representation and code formatting.

11

The encapsulation unit on the Presentation layer of the OSI Model is _____

Data

12

Define: Routing

the ability of the various network devices to move data packets from their source to their destination.

13

What is the 6th Layer of the OSI Model?

Presentation

14

The two most important portocols on the Transport layer of the TCP/IP Model are _____and _____

TCP & UDP

15

Define: OSI Model

framework and reference model to explain how different networking technologies work together and interact.

16

The primary job of the Network layer is to

Perform routing functions and a means of transmitting data packages.

17

What is the 1st Layer of the OSI Model?

Physical

18

Define: Application layer

contains all the services that are needed by the application

19

Define: header

describes what each layer should do.

20

Define: LLC

Logical Link Control sublayer, facilitate communications between the upper Network layer and the Physical layer.

21

Define: protocol

a set of rules to describe how a task works in a network environment

22

Define: bits

frames converted in the Physical layer.

23

Define: port address

a unique address inside the computer associated with a specific protocol, service, or application

24

Define: MAC

Media Access Control sublayer, provides access control to the media just as its name implies

25

The encapsulation unit on the Presentation layer of the OSI Model is _____

Data

26

Define: de-encapsulation

bits become frames, frames become packets, packets become segments, segments become data.

27

Define: simplex

one-way communications

28

Define: physical address

MAC address

29

Define: Transport layer

moves data to segments then sent for data transmission

30

Define: encapsulation

the process of taking data from a previous layer of the OSI Model and carrying it forward into the next layer.

31

Define: tailer

contains error correction information.

32

The two sublayers of the Data Link layer are _____, and _____

LLC & MAC

33

Define: TCP/IP Model

built around the TCP/IP protocol suite

34

Define: Half-duplex

a device can only send or recieve

35

The most important protocol on the Internet layer of the TCP/IP model is _____

Internet Protocol

36

Define: data

Top three layers of the OSI Model: The Application, Presentation, and Session layers.

37

Define: segment

Data going to the Transport layer.

38

The process of moving data from one layer of the OSI model to the next layer is called

encapsulation

39

Define: logical addresses

logically assigned depending on the Networking layer protocol being used

40

Define: Data Link layer
