What is the role of session layer and transport layer?

The session Layer is responsible for fetching or receiving data information from its previous layer (transport layer) and further sends data to the layer after it (presentation layer).

What are the main differences between transport and network layers?

The basic difference between network layer and transport layer is that transport layer protocol provides logical communication between processes running on different hosts , whereas network layer protocol provides logical communication between hosts.

What is session layer function?

The session layer provides the mechanism for opening, closing and managing a session between end-user application processes, i.e., a semi-permanent dialogue. An example of a session-layer protocol is the OSI protocol suite session-layer protocol, also known as X. 225 or ISO 8327.

What are the examples of transport layer?

The transport layer controls the reliability of communications through flow control, segmentation, and error control. Two great examples of transport protocols are TCP (as in TCP/IP) and UDP.

What is the relationship between transport layer and network layer?

Whereas a transport layer protocol provides logical communication between processes running on different hosts, a network layer protocol provides logical communication between hosts.

What is the difference between Application Layer and Transport Layer?

2 Answers. Transport is the act of moving data between two end points (think the “TCP” in TCP/IP). The application layer is the application that makes use of that transport (think HTTP or FTP, for example).

What are the functions of transport layer in computer networks?

The basic function of the Transport layer is to accept data from the session layer, split it up into smaller units if need be, pass these to the Network layer, and ensure that all the pieces arrive correctly at the other end.

What are the transport layer functions?

The main role of the transport layer is to provide the communication services directly to the application processes running on different hosts. The transport layer protocols are implemented in the end systems but not in the network routers. A computer network provides more than one protocol to the network applications.

What happens at the transport layer of the OSI model?

This layer is also responsible for flow control and making sure that segmented data is delivered over the network in the correct sequence. Layer 4 (the transport layer) uses the transmission control protocol (TCP) & user data protocol (UDP) to carry out its tasks.
