Match List-I with List-II:
| List-I | List-II | ||
|---|---|---|---|
| (A) | Modulation | (III) | Multiplying |
| (B) | Equalization | (I) | Noise Reducing |
| (C) | Hashing | (IV) | Authentication |
| (D) | Decryption | (II) | Getting Plain Text |
Show Hint
Decryption gives plain text, hashing helps authentication, and equalization improves signal quality.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Communication and security processes have different functions such as modulation, equalization, hashing and decryption.
Step 1: Modulation.
Modulation involves combining or multiplying a message signal with a carrier signal. \[ A \rightarrow III \]
Step 2: Equalization.
Equalization is used to reduce distortion and improve signal quality. \[ B \rightarrow I \]
Step 3: Hashing.
Hashing is used in authentication and integrity checking. \[ C \rightarrow IV \]
Step 4: Decryption.
Decryption converts cipher text back into plain text. \[ D \rightarrow II \] \[ \therefore \text{Correct Answer is (D)} \]
