What OSI layer identifies the communicating applications?Question 13Select one:a.Layer 1b.Layer 2c.Layer 3d.Layer 4e.Layer 5

Break Down the Problem

1. We need to identify which layer of the OSI model corresponds to the communicating applications.

Relevant Concepts

2. The OSI (Open Systems Interconnection) model consists of 7 layers:
   • Layer 1: Physical
   • Layer 2: Data Link
   • Layer 3: Network
   • Layer 4: Transport
   • Layer 5: Session
   • Layer 6: Presentation
   • Layer 7: Application

Analysis and Detail

3. The layer that directly manages the communication between applications is:
   • Layer 5 (Session) - establishes, manages, and terminates sessions between applications.
   • Layer 6 (Presentation) - translates data formats, encrypts, and compresses data.
   • Layer 7 (Application) - directly interacts with software applications to provide network services.

However, since the question asks specifically about "communicating applications," we must identify the correct answer from the provided options.

Verify and Summarize

4. The provided options list:
   • a. Layer 1
   • b. Layer 2
   • c. Layer 3
   • d. Layer 4
   • e. Layer 5

None of the options explicitly mention Layer 6 or Layer 7, but Layer 5 is the closest representation regarding session management.

Final Answer

The correct answer is e. Layer 5 (Session layer), as it is responsible for establishing and managing communication sessions between applications.
