Show answer & explanation
Correct answer: A
Answer: a → Manage dialogue control; b → Virtual terminal software; c → Semantics of the information transmitted; d → Flow control.
Session layer — Manages dialogue control: establishes, maintains, and terminates sessions between applications (a → Manage dialogue control).
Application layer — Provides user-level services such as virtual terminal software (b → Virtual terminal software).
Presentation layer — Handles data representation and semantics (syntax, encryption, compression), so it matches semantics of transmitted information (c → Semantics of the information transmitted).
Transport layer — Ensures end-to-end communication services such as flow control and error recovery (d → Flow control).
Quick summary: Match each layer to its primary responsibility rather than specific programs. Application provides services to users, presentation handles representation/semantics, session controls dialogues, and transport manages reliable transfer and flow control.
