Q3.         Match the following:

   1.  Terminal / Host          A. Traffic is bi-directional , asymmetric and  moderate to high

   2.  Client / Server           B. Traffic is bi-directional, symmetric, and high

   3.  Peer / Peer               C. Low volume character traffic

A.  1 -> B     2 -> C      3 -> A

                        B.  1 -> A     2 -> B      3 -> C

                        C.  1 -> C     2 -> B      3 -> A

                        D.  1 -> C    2 -> A      3 -> B  

Ans: D

Explanation:

1. Terminal / Host: Applications based on Terminal / Host are low - volume character traffic. The  traffic from the terminal will be a few characters while the Host returns screen full of characters.

2. Client / Server : The traffic flow in Client / server environment is bi-directional and asymmetric. Traffic sent to the host is usually less than 100 bytes and the return traffic from the host can be more than 1500 bytes. HHTP, FTP are examples of Client / Server Protocols.

3. Peer/ Peer: In peer to peer environment, traffic flow is bi-directional and symmetric. Peer to peer communication is commonly used in work groups.
