Networking Layers: TCP/IP & OSI Model
This solution explains the matching of networking protocol layers (List-I) with their corresponding OSI model layers or functions (List-II).
IP Layer Matching
The IP layer, containing the Internet Protocol (IP), is fundamental for packet routing and addressing. This function is equivalent to the Network layer (Layer 3) in the OSI reference model.
Match: P to 2.
TCP/UDP Layer Matching
The TCP/UDP layer includes protocols like TCP and UDP, which manage end-to-end connection management and data segmentation. These are the core functions of the Transport layer (Layer 4) in the OSI model.
Match: Q to 3.
TCP/IP Matching Context
In this context, TCP/IP often refers to application-level protocols (e.g., HTTP, FTP) that operate on top of the TCP/IP suite. These protocols belong to the Application layer (Layer 7) of the OSI model.
Match: R to 4.
Physical Layer Role
The Physical layer is concerned with the transmission of raw bits over a physical medium. This directly aligns with the function 'Transmission of bits'.
Match: S to 1.
List Matching Summary
| List-I Item | List-II Item | OSI Layer/Function Match |
| P. IP layer | 2. Network layer of the OSI reference model | Network Layer |
| Q. TCP/UDP layer | 3. Transport layer of the OSI reference model | Transport Layer |
| R. TCP/IP | 4. Application layer of the OSI reference model | Application Layer |
| S. Physical layer | 1. Transmission of bits | Bit Transmission |
The correct matching combination derived is P-2, Q-3, R-4, S-1.
