CS702(C) Unit 1 Traditional Networks & TCP/IP study material for RGPV CSE 7th Semester. Learn LAN, MAN, WAN, Internet, bridges, routers, TCP/IP architecture, ARP/RARP, IP addressing, IP datagram, ICMP, subnetting, CIDR, DNS, NAT, VLAN and IPv6.
Unit 1 reviews traditional computer networks and TCP/IP fundamentals. It covers addressing, routing basics, IP datagram delivery, subnetting, NAT, DNS, VLAN and IPv6 concepts that build the foundation for wireless and mobile computing.
Understand LAN, MAN, WAN, Internet, Intranet, bridges and routers.
Learn TCP/IP architecture, ARP, RARP, IP addressing and IP datagram format.
Study DNS, NAT, firewalls, VLAN concepts, VLAN tagging and IPv6 header.
Complete syllabus-based topics of Wireless & Mobile Computing Unit 1.
LAN covers a small area, MAN covers a city-level area and WAN connects networks over large geographical distances.
Intranet is a private internal network, while Internet is a global public network connecting millions of systems.
Bridges and routers are used to connect different network segments and forward data efficiently.
TCP/IP architecture is a layered model that includes network access, internet, transport and application layers.
ARP maps IP address to MAC address, while RARP maps MAC address to IP address.
IP addressing uniquely identifies devices in a network and helps in routing packets.
IP datagram contains header and data fields used for packet delivery across networks.
Routing tables store destination networks, next hop and interface information for forwarding packets.
ICMP is used for error reporting and diagnostics, such as destination unreachable and echo request/reply.
Subnetting divides a large network into smaller subnetworks for better management and address utilization.
Supernetting combines multiple networks, while CIDR allows flexible IP address allocation.
DNS translates domain names into IP addresses so users can access websites using readable names.
NAT translates private IP addresses into public IP addresses. SNAT changes source address and DNAT changes destination address.
Firewalls monitor and control incoming and outgoing network traffic based on security rules.
VLAN logically divides a physical LAN into multiple virtual networks for better security and management.
VLAN tagging adds VLAN information to frames so switches can identify traffic belonging to different VLANs.
IPv6 uses 128-bit addresses and provides a very large address space compared to IPv4.
IPv6 header is simpler than IPv4 header and improves routing efficiency.
ARP: IP address ko MAC address me convert karta hai.
Subnetting: Network ko chhote parts me divide karta hai.
CIDR: Flexible IP address allocation method.
NAT: Private IP ko public IP me translate karta hai.
VLAN: Same physical LAN ke andar logical networks banata hai.
IPv6: 128-bit address system with large address space.

TCP/IP is a protocol suite used for communication over networks and the Internet.
ARP maps an IP address to its corresponding MAC address.
Subnetting divides a large network into smaller subnetworks.
NAT translates private IP addresses into public IP addresses.
VLAN is a logical network created inside a physical LAN.
IPv6 provides a larger address space and improved routing compared to IPv4.
