1. Introduction to Networking Prof. Ananjan Maiti

2. Overview of the course OSI and TCP/IP Models:  Open Systems Interconnection (OSI)  Transmission Control Protocol/Internet Protocol (TCP/IP) models  There are seven layers in the OSI Model, and four in the TCP/IP model.  This is because TCP/IP assumes that applications will take care of everything beyond the Transport layer.

3. Overview of the course (Cont.) Networking Devices:  Hubs, bridges, switches, routers, gateways, firewalls etc...  Hubs, switches, routers, and access points are used to connect computers together on a network, but each of them has different capabilities.  Each of these devices operates at different layers in OSI and TCP/IP models.

4. LAN Technologies:  Used for connecting (within a building )  PC/terminals, computers and  printers other geographically limited areas.  This chapter discusses  medium access control techniques,  random access techniques,  static channelization techniques,  Ethernet, Token Ring  ends with error detection techniques at data link layer.  MAC addresses  ARP translates IP addresses into hardware addresses (MAC)  RARP translates machines addresses (MAC) into IP addresses.

5. IP Addressing  Mainly two type :IPv4 and IPv6 addressing.  It provides in-depth analysis of classes of IP addressing  subnet masks  Subnetting/ Supernetting  Classless InterDomain Routing [CIDR]  Variable Length Subnet Mask [VLSM]  message formats of both IPv4 and IPv6.

6. IP /Network routing protocols Routing Protocol : Routing Information Protocol Open Shortest Path First [OSPF] Border Gateway Protocol.

7. TCP and UDP 1. Node-to-node delivery: At the data-link level, delivery of frames take place between two nodes connected by a point-to-point link or a LAN, by using the data-link layers address, say MAC address. 2. Host-to-host delivery: At the network level, delivery of datagrams can take place between two hosts by using IP address.

8. TCP Flow Control TCP Congestion Control Session Layer Dialog management Synchronization Activity management Exception handling
