Question

Network Virtual Terminal is associated with the following: (A) Software Version (B) Remote Host (C) Encryption (D) Translation Choose the correct answer from the options given below:

Hint:

Think of NVT as a "universal translator" for terminals. It allows a client to talk to a remote host by translating both their languages into a common, simple format.

Answer 1

Step 1: Define Network Virtual Terminal (NVT). NVT is a concept used in the TELNET protocol. It provides a standardized, intermediate representation of a terminal. This allows a client from any type of computer to communicate with a server on any other type of computer without them needing to know the specific details of each other's hardware.

Step 2: Analyze the associations. \[\begin{array}{rl} \bullet & \text{(A) Software Version: NVT is a protocol standard, not tied to a specific software version.} \\ \bullet & \text{(B) Remote Host: The entire purpose of NVT and TELNET is to connect to and interact with a remote host. This is a primary association.} \\ \bullet & \text{(C) Encryption: The original TELNET protocol, which uses NVT, does not include encryption, which is its major security flaw.} \\ \bullet & \text{(D) Translation: NVT works by having both the client and server translate their local terminal conventions into the NVT standard and vice-versa. Translation is a core function of how NVT operates.} \\ \end{array}\]

Step 3: Conclude. NVT is directly associated with connecting to a Remote Host (B) and the process of Translation (D). Since no option is "(B) and (D) only", the question is flawed.
