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 )
Physical Layer
Data link Layer
Network Layer
Transport Layer
Session Layer
Presentation Layer
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.
