Zorluk: KolayOSI Model Layers and Functions

Match each OSI reference model layer on the left with its core function on the right.

  • Layer 2 - Data Link LayerHandles physical MAC addressing and frame delivery within a local segment
  • Layer 3 - Network LayerProvides logical IP addressing and routing packets between different networks
  • Layer 4 - Transport LayerManages end-to-end connection reliability, segmentation, and port numbering
  • Layer 7 - Application LayerInterfaces directly with user software applications and network services

Cevap

The Data Link layer (Layer 2) matches MAC addressing and local frame delivery; the Network layer (Layer 3) matches logical IP addressing and packet routing; the Transport layer (Layer 4) matches end-to-end connection management and port numbers; and the Application layer (Layer 7) matches direct interfacing with end-user software.
Each OSI model layer performs distinct functions: Layer 2 uses MAC addresses for local frame delivery; Layer 3 manages logical IP addresses for network routing; Layer 4 handles end-to-end delivery using TCP/UDP port numbers; and Layer 7 enables network interaction for user applications.

Adım Adım Çözüm

1
Identify the primary function of Layer 2 (Data Link).
Layer 2 uses physical MAC addresses and frames for local node communication.
Hardware addressing and framing are core Data Link responsibilities.
2
Identify the primary function of Layer 3 (Network).
Layer 3 utilizes logical IP addresses to route packets between disparate networks.
Inter-network routing requires logical network addressing at Layer 3.
3
Identify the primary function of Layer 4 (Transport).
Layer 4 uses port numbers to segment data and manage end-to-end process delivery.
Process-to-process communication and flow control operate at Layer 4.
4
Identify the primary function of Layer 7 (Application).
Layer 7 provides standard network protocol interfaces for software applications.
High-level user network processes operate at the top of the OSI stack.
