1. DATA COMMUNICATION Course Code : N-OECET501T Course In-charge:- Prof. Sharda Chaudhari

2. Before we begin……! What is the subject all about? Communication Fundamentals Network LAN Topologies Network Layers Networking devices Multimedia, Security, and Cloud Computation over the Internet

3. Why to study this subject? Internet has become one of the most important components of our life. We browse the Web, check e-mails, make VoIP phone calls, and have video conferences via computers. All of these applications are made possible by networking computers together, and this complex network of computers is usually referred to as the Internet.  This course is designed to give you a clear understanding of how networks, from in-home local area networks, or LANS, to the massive and global Internet, are built and how they allow us to use computers to share information and communicate with one another.
