No, At each layer, protocols perform servers unique to that layer. While performing those services, the protocols also interact with protocols in the layers directly above and below. In addition, at the top of the OSI model, Application layer protocols interact with the software you use. At the bottom, Phsyical layer services act on the networking cables and connectors to issue and receive signals.
Network Layer
the network layer --> check your question. ^^^^^^^^^^^^^^^^^^^^^^^^^^^ That is totally not the right answer, how about you actually read the book for the course. It is the data link layer that does encapsulation. I agree - its the Data Link Layer which encapsulates the Network layer...NOT the Network Layer.
Network Layer

network session layer Session Layer (Layer 5) The session layer permits two parties to hold ongoing communications called a session across a network.
Transport layer and Network layer.

Router works in Network Layer of OSI model
identifies the network layer protocol makes the connection with the upper layers insulates network layer protocols from changes in physical equipment
insulates network layer protocols from changes in physical equipment makes the connection with the upper layers identifies the source and destination identifies the network layer protocol
Network Layer
TCP operates at Layer 4 which is Transport of the OSI Model!
The network layer is the third level of the Open Systems Interconnection Model (OSI Model) and the layer that provides data routing paths for network communication. Data is transferred in the form of packets via logical network paths in an ordered format controlled by the network layer. The network layer provides the functional and procedural means of transferring variable-length data sequences from a source to a destination host via one or more networks, while maintaining the quality of service functions. networkrepairs.ca
Layer 3 i.e, network layer of the OSI model is used to IP addressing.
