OSI Model
Network layer is used when data is to be delivered across network. So, for delivering within a network, there is no need for network layer (Ref: Pg-49, Computer Networks, Forouzan, 2 Edition). So in that case will Transport layer directly communicate with Data Link layer ? Or will Network layer be in picture, but do nothing other than simply passing data to Transport layer ?

Computer Network
What is the difference between broadcasting at Data Link Layer and broadcasting at Network Layer? Broadcasting at Data Link Layer is done via MAC address FF:FF:FF:FF:FF:FF while broadcasting at Network Layer is done using broadcast IP address 255.255.255.255 but they essentially do the same thing, sending a packet to every other node in the network.
