Match each OSI model layer on the left with its primary operational function and corresponding Protocol Data Unit (PDU) characteristics on the right.
- Data Link Layer (Layer 2)Encapsulates data into Frames using physical MAC addressing for node-to-node transmission within a local network segment.
- Network Layer (Layer 3)Encapsulates data into Packets with logical IP addresses to perform path determination and routing across networks.
- Transport Layer (Layer 4)Organizes data into Segments using port numbers to manage end-to-end process-to-process communication and flow control.
- Presentation Layer (Layer 6)Handles syntax translation, data compression, and encryption to ensure data is properly formatted for application use.
Cevap
The Data Link Layer (Layer 2) pairs with node-to-node frame delivery via MAC addresses; the Network Layer (Layer 3) pairs with packet routing via IP addresses; the Transport Layer (Layer 4) pairs with end-to-end process multiplexing via segments and ports; and the Presentation Layer (Layer 6) pairs with syntax translation, compression, and encryption.
Each OSI layer serves a specific purpose in network communications: Layer 2 uses Frames and MAC addresses for local transmission; Layer 3 uses Packets and IP addresses for routing; Layer 4 uses Segments and port numbers for transport multiplexing; and Layer 6 provides data translation, compression, and encryption.
