Question

Which of the following OSI layers is responsible for the segmentation, multiplexing, flow control and host-to-host communication services for applications?

- Presentation Layer
- Network Layer
- Transport Layer
- Session Layer
- Datalink Layer

Answer 1

Transport Layer

Step-by-step explanation:

• Transport Layer is responsible for host-to-host communications of applications.
• OSI model has seven layers while other models like TCP/IP has four layers.
• OSI model stands for Open Systems Interconnection.
• The seven layers of OSI model architecture are the following starting from the Hardware Layers ( Layers in Hardware Systems ) to Software Layers ( Layers in Software Systems )

1. Physical Layer
2. Data link Layer
3. Network Layer
4. Transport Layer
5. Session Layer
6. Presentation Layer
7. Application Layer

• Each layer has its unique functionality which is responsible for the proper functioning of the communication services.
• Transport Layer is responsible for multiplexing, segmentation, flow control and host-to-host communication services.
