Data link layer : CSMA/CD, CSMA/CA 2. Network layer: Addressing of ipv4, basics of ipv6, CIDR, Routing protocol, ICMP 3. Transport layer: TCP, UDP, Congestion control, Port no. 4. Network security: Diffie Hellman, RSA algorithm, digital signature. 5.Protocol.: RARP, ARP, DHCP, DNS etc. Note that it is important to solve previous year gate questions on CN because CN is such a deep subject. 0 votes 0 votes Shaik Masthan commented Feb 8, 2019 reply Follow Share as per me, CN is a beautiful subject ! but knowing the subject, we can't guarantee good marks from this ! coming to reading standard text books, first listen some basic videos then start reading the standard books, if you directly enter into the subject via standard books, you feel bored.
