Routers operate at which layer of the OSI model? Network Transport Datalink Session.
Bits are packaged into frames at which layer of the OSI model? Data Link Presentation Application Transport.
Which of the following are benefits of using a layered network model? it facilitates troubleshooting it breaks the complex process of networking into more manageable chunks it allows layers developed by different vendors to interoperate. it specifies how changes to one layer must be propagated through the other layers it focuses on details rather than general functions of networking.
The layers of the OSI model, from the top down, are: application, presentation, session, transport, network, data link, physical session, presentation, data transport, MAC, network, physical presentation, application, session, network, transport, data link, physical physical, data link, network, transport, session, presentation, application application, encryption, network, transport, logical link control, physical.
Which of the following operate at the presentation layer? MIDI FTP SMTP TFTP JPEG.
Which of the following are transport layer protocols? TCP and UDP IP FTAM IP and TFTP TFTP.
Which of the following are considered to be the upper layer protocols? presentation and session application and presentation application, presentation, and session application, presentation, session, and transport application.
