Content Quiz 10-1: Computer Networks - Parts 4 - 6 (The OSI Model, TCP/IP & Wireshark)

The open systems interconnection model specifies the _______ of each layer, but does not specify what ______ each layer will use

function, protocol

OSI Layers and their responsibility

Application Layer - handles the user interface to networking services

Presentation Layer - handles formatting the details for the data

Session Layer - handles the initiation, maintenance, and termination of the connection

Transport Layer - handles the transfer of messages between the sender and the reciever

Network Layer - handles the path or route between source and destination through the network

Data Link Layer - handles the transmission of data between two nodes

Physical Layer - handles the transmission of raw bits over the communication channel

In the TCP/IP model, the ___ layer covers the same functionality as the application, presentation, and session layers in the OSI model.The Internet layer in the TCP/IP model corresponds with the __ layer in the OSI model.The ___ layer in the TCP/IP model corresponds with the the data link and physical layers in the OSI model.

-application

-network

-link

True or False. Wireshark packet captures can be exported.

true

OSI layer with the protocols

Application Layer - HTTP, SMTP, FTP, Telnet

Presentation Layer - ASCII, MP3, JPEG, MPEG

Session Layer - Netbios

Transport Layer - TCP, UDP

Network Layer - IP

Data Link Layer - Ethernet

Physical Layer - Cat5 Cable

Unlike in the OSI Model, _____ are specified and are part of the TCP/IP reference model itself.

protocols

In Wireshark, you can see that frame corresponds to the ____ layer and you will be able to similarly see how different protocols correspond to different layers in the OSI model.

physical

Wireshark is software that can capture ____ that are sent and received over your network for analysis.

packets

Proxy servers and firewalls operate at the _____ layer.

transport

The Statistics-->Protocol Hierarchy menu item will give you the layout of all of the different ________ found by Wireshark.

protocols
