The network layer is the layer that is responsible for routing packets on the network. This is the layer in which Internet protocol operates. In the seven layer OSI model, the network layer is the third layer from the bottom.
The Physical Layer
Layer 3 (network layer).

The network layer is responsible for addressing nodes in a logical way. It is also responsible for making decisions on routing a packet from one network to another. Without the network layer it would not be possible to send a packet outside of your own local network.
The network layer is responsible for addressing nodes in a logical way. It is also responsible for making decisions on routing a packet from one network to another. In a broadcast network, routing is not needed. A transmission from any attached station is received by all other attached stations. Other functions,such as sequencing, flow control, error control, can be done at layer 2. The MAC sublayer is responsible for addressing across the LAN. With the Data link layer and its sublayers (MAC & LLC), no network layer is needed.
Transport layer is responsible for reliable delivery of information, error correction and so on.
