i. Connection Managementii. Flow Controliii. Error Controliv. Reliable, in-order delivery.
(b) Explain the four header fields present in a UDP segment.
(c) Each host on the Internet is currently assigned an IP address 32 bits long (Ipv4). Ipv4 addresses are generally written as a series of four decimal numbers. IPv4 addresses traditionally belong to one of five classes of address, depending on the type of network.
i. Give the address range for a Class B network.ii. What are Class D network addresses primarily used for? iii. Will two hosts A and B with addresses 192.168.27.27 and 192.168.27.37 respectively communicate directly with each other if they share a subnet mask of 255.255.255.240?iv. Explain one short-term technique which has been used to solve the shortage of Ipv4 addresses.v. Give basic differences between IPv4 and IPv6.
