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, used in the TELNET protocol, is a standardized terminal representation. It facilitates communication between diverse computer systems by providing a common intermediate format, eliminating the need for specific hardware knowledge.

Step 2: Analyze the associations. \[\begin{array}{rl} \bullet & \text{(A) Software Version: NVT is a protocol standard, not version-specific.} \\ \bullet & \text{(B) Remote Host: NVT and TELNET's core function is remote host connection and interaction.} \\ \bullet & \text{(C) Encryption: The original TELNET protocol, utilizing NVT, lacks encryption, a significant security vulnerability.} \\ \bullet & \text{(D) Translation: NVT relies on client and server translation to and from the NVT standard. Translation is fundamental to NVT's operation.} \\ \end{array}\]

Step 3: Conclude. NVT is directly linked to Remote Host connection (B) and Translation (D). As there isn't an option for "(B) and (D) only", the question contains an error.
