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.
