Fragmentation Ipv4-Ipv6
True or false - 1. In Ipv4 fragmentation can be done both at Source and intermediate routers. 2. In Ipv6 fragmentation can be done only at Source and not intermediate routers. 3. In both IPv6/4 reassembly is done only at the destination. 4. ... fragmentation done at the Source in Ipv4? Should the 1) be false since segmentation is done and hence fragmentation can be avoided?

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 ?
