2.i. Explain packet switching. A packet passes through 4 routers with each router introducing 2 ms processing delay. Transmission delay per link is 5 ms. Calculate total end-to-end delay (ignore propagation).

ii. Differentiate between IPv4 and IPv6. Given the IP address 192.168.10.0/24, calculate. Number of subnets if borrowed bits = 3 and hosts per subnet.
