8)Transport layer:

Transport layer is fourth layer. Stains flow control of data.error checking and recovery data.it accepts data from above,splits it into small units.

9)networklayer:

Networklayer controls the operations of the subnet which are identifiable parts of the network.it decides how the data will be sent to the recipient device.
