Match the OSI Layers List I with Protocol/technology in List IILIST-I (OSI Layers) LIST-II (Protocol/technology) A. Physical Layer I. DNS (Domain Name System) B. Network Layer II. PPTP (Point-to-Point Tunnelling Protocol) C. Session Layer III. Fibre Optics. D. Application Layer IV. ICMP (Internet Control Message Protocol)
OSI Layer to Protocol Matching
The question requires matching the layers of the OSI model (List I) with their corresponding protocols or technologies (List II).
The correct pairings are identified as follows:
- A. Physical Layer is matched with III. Fibre Optics because the Physical Layer deals with the physical transmission medium and signaling. Fibre Optics is a technology used for this transmission.
- B. Network Layer is matched with IV. ICMP (Internet Control Message Protocol) because the Network Layer handles logical addressing and routing. ICMP is a core protocol used at this layer for error reporting and diagnostics.
- C. Session Layer is matched with II. PPTP (Point-to-Point Tunnelling Protocol) because the Session Layer manages communication sessions between devices. PPTP is used to establish and manage VPN tunnels, which involves session control.
- D. Application Layer is matched with I. DNS (Domain Name System) because the Application Layer provides network services directly to end-user applications. DNS is a critical service for name resolution used by applications.
Therefore, the correct match is A-III, B-IV, C-II, D-I.
