Zorluk: OrtaOSI Model Layers and Functions

A network engineer is troubleshooting a cross-platform file transfer utility operating between a legacy mainframe and a modern Linux server. While the network connection establishes without error, transferred text files display corrupt characters because the source host formats data using EBCDIC character encoding while the destination expects ASCII. Which OSI model layer is directly responsible for handling character set translation and data syntax formatting between disparate systems?

  1. A
    Application Layer
  2. B
    Session Layer
  3. Presentation LayerCevap
  4. D
    Transport Layer

Cevap

Presentation Layer
The Presentation Layer (Layer 6) serves as the network's data translator. It handles tasks such as character code conversion (e.g., EBCDIC to ASCII), data compression, encryption, and syntax formatting, enabling distinct computer systems with different internal data representations to communicate effectively.

Adım Adım Çözüm

1
Analyze the reported technical issue described in the scenario.
The issue involves mismatched character encodings (EBCDIC versus ASCII) and syntax formatting between two different computer architectures.
Identifying the functional requirement (character translation and data representation) narrows down which OSI layer handles this specific task.
2
Map the functional requirement to OSI Model layer responsibilities.
Layer 6 (Presentation Layer) is specifically defined to manage data representation, character code translation, formatting, syntax standardization, encryption, and compression.
The Presentation Layer acts as the translator for the network, ensuring heterogeneous systems can interpret application data correctly.
