Course content

1 section • 5 lectures • 1h 44m total length

Introduction21:07
Introduce concept of computer networks as connected devices sharing resources, and outline IP addresses, class ranges, and local, metropolitan, wide area, and personal area networks, data transmission modes, and topologies.
Circuit and Packet Switching17:35
Explore circuit switching and packet switching, including datagram and virtual circuit approaches. Learn how connection setup, data transfer, and teardown arrive in these switching methods.
Layered Architecture20:19
Describe the OSI model and TCP/IP layering, and explain each layer from physical to application using a real-world analogy.
Fixed Length Subnet Mask25:51
Explore subnetting fundamentals, including fixed length subnet masks, classful vs classless addressing, and the comparison of vlsm with flsm, plus block size, network and broadcast addresses for IPv4 subnets.
Variable Length Subnet Mask19:32
Explain variable length subnet mask (VLSM) and its use with classful addressing, showing how different subnets fit varying hosts while computing masks, networks, and broadcast addresses.

Requirements

Description

The course “Core Networking Concepts and IPv4 Addressing” provides a strong foundation in the fundamentals of computer networking and the essential principles of Internet Protocol version 4 (IPv4). Designed for beginners, this course introduces students to the structure, components, and operations of computer networks, enabling them to understand how devices communicate and exchange packets, data and information through Ip address .

Students will explore different types of networks such as LAN, WAN, MAN, and PAN, and study the role of networking devices including routers, switches, and hubs. The course also covers the OSI and TCP/IP reference models, offering a clear understanding of how data moves across layers in a network.

A major focus of this course is IPv4 addressing. Students will learn the structure of IPv4 addresses, address classes (A, B, C, D, E), and the distinction between public, private, loopback, and broadcast addresses. The course also introduces addressing methodologies such as unicast, broadcast, multicast, and anycast. Through subnetting and CIDR (Classless Inter-Domain Routing), students will gain practical skills in efficient IP allocation.

By the end of the course, learners will be able to design, configure, and troubleshoot IPv4-based networks, preparing them for advanced studies, certifications, or entry-level careers in networking and IT.
