Chapter 2 Flashcards
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
The encapsulation unit on the Data Link layer of the OSI Model is _____
Frame
Define: Physical layer
all aspects of physically moving data from one computer to the next.
_____ are used for node-to-node communications on a network. Logical address, Port address, Physical address, Socket
Physical Address
Define: frame
The packet becomes this in the Data Link layer.
What is the 7th Layer of the OSI Model?
Application
The process of moving data from one layer of the OSI model to the next layer is called
encapsulation
The Application layer of the TCP/IP Model corresponds to the blank layer(s) of the OSI model
Session and Presentation
Define: frame synchronization
a method of finding valid data in a transmission that consists of data frames
The primary job of the Presentation layer concerned with
data representation and code formatting.
The encapsulation unit on the Presentation layer of the OSI Model is _____
Data
Define: Routing
the ability of the various network devices to move data packets from their source to their destination.
What is the 6th Layer of the OSI Model?
Presentation
The two most important portocols on the Transport layer of the TCP/IP Model are _____and _____
TCP & UDP
Define: OSI Model
framework and reference model to explain how different networking technologies work together and interact.
The primary job of the Network layer is to
Perform routing functions and a means of transmitting data packages.
What is the 1st Layer of the OSI Model?
Physical
Define: Application layer
contains all the services that are needed by the application
Define: header
describes what each layer should do.
Define: LLC
Logical Link Control sublayer, facilitate communications between the upper Network layer and the Physical layer.
Define: protocol
a set of rules to describe how a task works in a network environment
Define: bits
frames converted in the Physical layer.
Define: port address
a unique address inside the computer associated with a specific protocol, service, or application
Define: MAC
Media Access Control sublayer, provides access control to the media just as its name implies
The encapsulation unit on the Presentation layer of the OSI Model is _____
Data
Define: de-encapsulation
bits become frames, frames become packets, packets become segments, segments become data.
Define: simplex
one-way communications
Define: physical address
MAC address
Define: Transport layer
moves data to segments then sent for data transmission
Define: encapsulation
the process of taking data from a previous layer of the OSI Model and carrying it forward into the next layer.
Define: tailer
contains error correction information.
The two sublayers of the Data Link layer are _____, and _____
LLC & MAC
Define: TCP/IP Model
built around the TCP/IP protocol suite
Define: Half-duplex
a device can only send or recieve
The most important protocol on the Internet layer of the TCP/IP model is _____
Internet Protocol
Define: data
Top three layers of the OSI Model: The Application, Presentation, and Session layers.
Define: segment
Data going to the Transport layer.
The process of moving data from one layer of the OSI model to the next layer is called
encapsulation
Define: logical addresses
logically assigned depending on the Networking layer protocol being used
Define: Data Link layer
concerned with moving data from one computer to another.
Define: connectionless protocol
does not ask for verification that a data packet has reached its destination.
Define: Network layer
moves data in the form of packets from one end of the network to the other.
Which layer of the OSI Model is responsible for segmenting data and sequencing it for the rest of the OSI model
Transport
The encapsulation unit on the Network layer of the OSI Model is _____
Packet
What is the 5th Layer of the OSI Model?
Session
What is the 2nd Layer of the OSI Model?
Data Link
What is the 4th Layer of the OSI Model?
Transport
Define: packet
The segment becomes this in the Networking layer.
What is the 3rd Layer of the OSI Model?
Network
Which layer of the OSI model is concerned with reliably getting data from one computer to another
Data Link
Define: connection-oriented protocol
asks for verification that a data packet has reached its destination
define: protocol suite
made up of a large number of protocols that allow computers to communicate
Define: Session layer
manages dialog between networked devices.
The primary function of the Physical Layer
Transfer the bits
