THE OSI model

The Network layer is layer 3. The network layer is responsible for packet forwarding including routing through intermediate routers.
This is layer 4 which is the transport layer. This layer provides reliable transport and flow control across a network.
The Data Link layer is responsible for providing physical addressing and media access procedures. This layer also transfers data between adjacent network nodes in a wide area network (WAN) or nodes that are on the same local area network (LAN).
The OSI model was
developed in the early
1980s for the purpose
of standardizing the
communicate on a
network. The model
features the following
Session is layer 5 in OSI. Session establishes, manages, and terminates the connections between the local and remote applications.
When a user sends data, such as an email, the encapsulation process, starts at the application layer. The application layer provides network access to applications. Information flows through the top three layers and is considered to be data when it gets down to the transport layer.
Layer six. The presentation layer will transform the data to a standard interface. The data is transformed for the application layer.
The Physical Layer consists of the basic networking hardware transmission technologies on a network
