From solving network related issues to discussing applications of these ideas, they have covered the practical aspects of networking.

Why take this Work?

The 20th Century has all been about knowledge gathering, processing and distribution. Historically few decades, the world has seen tremendous growth in these fields, from phone networks to radio and television, from highly centralized huge computers to the smart-phones and smart-watches of today. The net has been instrumental in connecting this world together, to billions of people and millions of devices. And this trend will continue to grow quickly throughout the 21st century !

How is this work designed?

This Work is structured in to following sections:

Overview: This section introduces you to the course, provides information about the author, course structure and gives you answers to some of the frequently asked questions by students.
Network basics: This section provides fundamental information on computer networks. Network topologies, different types of networks like LAN, WAN, MAN and wireless networks are explained. One of the most important communication model of computer networks, the OSI Reference Model is discussed. Having the knowledge on OSI Model helps in understanding network functionalities better.
Physical Layer: This section deals with techniques like Switching and Multiplexing which focus on effectively utilizing the existing bandwidth to accommodate the high rate of data communication.
Datalink Layer: This section begins with a lecture on framing, a technique to demarcate the frame boundaries. Later we discuss the flow and error control mechanisms, different error detection and correction techniques like Parity Check, Checksum and Hamming Codes.
Network Layer: In this section header formats of IPv4 and IPv6 datagrams are explained.
Transport Layer: This section explains the Transport Layer protocols that provide service to the Network Layer. Header format, features and services provided by TCP and UDP are explained.
Application Layer: This section begins with Cryptography basics. Encryption algorithms like RSA are explained with examples. Also, File Transfer Protocol is explained.
