Matching Network Protocols to Layers
This question requires matching specific network protocols (listed in LIST-I) to their corresponding layers in the OSI or TCP/IP model (listed in LIST-II).
Protocol Identification and Layer Assignment
- A. SMTP (Simple Mail Transfer Protocol): Used for sending email messages, it operates at the Application layer.
- B. BGP (Border Gateway Protocol): A routing protocol that exchanges routing and reachability information among autonomous systems on the Internet, operating at the Network layer.
- C. TCP (Transmission Control Protocol): Provides reliable data transmission between applications, operating at the Transport layer.
- D. PPP (Point-to-Point Protocol): Used to establish direct connections between two network nodes, operating at the Data Link Layer.
Final Matching Summary
Based on the identification above, the correct matches are:
| LIST-I (Protocol) | LIST-II (Layer) |
| A. SMTP | I. Application layer |
| B. BGP | IV. Network Layer |
| C. TCP | II. Transport layer |
| D. PPP | III. Data Link Layer |
Therefore, the correct matching is A-I, B-IV, C-II, D-III.
