transport layer
Transport layer is responsible for reliable delivery of information, error correction and so on.
Segmentation of data happens at transport layer. Because transport layer is responsible for successful transportation of data through out the network.
delivers data reliably across the network using TCP
because the tcp is reliable
The Transport layer which handles segments is responsible for End-to-End connections and reliability. Problems at this layer can negatively impact reliable message delivery. Although the Transport layer is supposed to be where reliability is provided, problems at the Network layer where packets are handled can also significantly affect reliable message delivery if the path determination and/or IP (logical addressing) are messed up.
Transport layer is the fourth layer in the OSI model. Transport layer is responsible for process to process delivery of entire message. Other than that it also control connection, flow of data and error , thus will resend the packet if it get lost in between.
papillary layer is responsible for fingerprints
CFC's are responsible. They deplete the ozone layer.
The ozone layer is responsible for absorbing harmful rays from the sun. These are UV rays.
physical layer
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 application layer (layer 7) is responsible for file transfer operations.
