Refer to the exhibit. How will data files get retrieved from the server?

The client establishes a two-way connection to the server on port 21 for file transfer.

From the perspective of computer A, port 21 is used to signal a push to the server, and port 20 is used to signal a pull from the server.

There is a connection established to send files from the client to the server and a second connection to get files from the server to the client.

Computer A establishes a connection to the server on port 21 for control and uses a second connection on port 20 to download and upload files.

    What are two primary responsibilities of the Ethernet MAC sublayer? (Choose two.)
    frame delimiting
    data encapsulation
    logical addressing
    error detection
    accessing the media

    • Lost says:

      And this one ? which answer is correct?

    • didabest says:

      -data encapsulation
      -accessing the media

    • Bonn says:

      Two primary responsibilities:
      1. data encapsulation
      provides 3 primary functions:
      a. frame delimiting
      b. addressing
      c. error detection

      In forming the frame, the MAC layer adds a header and trailer to the Layer 3 PDU.

      Purpose of framing:

      I. The use of frames aids in the transmission of bits as they are placed on the media and in the grouping of bits at the receiving node.
      II. Provides important delimters that are used to identify a group of bits that make up a frame.This process provides synchronization betwen the transmitting and receiving nodes

      The encapsulation process also provides for Data Link layer addressing. Each Ethernet header added in the frame contains the physical address (MAC address) that enables a frame to be delivered to a destination node.

      An additional function of data encapsulation is error detection. Each Ethernet frame contains a trailer with a cyclic redundancy check (CRC) of the frame contents. After reception of a frame, the receiving node creates a CRC to compare to the one in the frame. If these two CRC calculations match, the frame can be trusted to have been received without error.

      2. media access control -contols the frame placement on and off the media
      -media recovery

    To enhance security in a network, the network administrator uses these commands:
