2. Some Revision Points – Part One CSMA/CD OSI Reference model Traffic Generation calculation Topologies

3. Using the flow diagram opposite; write the algorithm for CSMA/CD

4. OSI Reference Model Can you remember the layers of the OSI reference model? Write the layer down in order

5. Traffic Generation The diagram above has 16 nodes attached to a central hub. Each node has a packet size of 1500 bytes. Each node sends a packet every 0.02 seconds. How much data will one node generate How much data will the whole network generate
