Basics of Networking
About :
This module lays the foundation for understanding how computer networks function, communicate, and stay secure. It is designed for beginners and anyone who wants to build a strong base in networking before diving into advanced cybersecurity concepts.
01
We start with the essentials — how devices connect, share information, and form networks. Students learn what makes up a network and why networking is critical for every modern business and system.
02
From a small Local Area Network (LAN) in homes or offices to large-scale Wide Area Networks (WAN) connecting cities and countries, learners explore different network types, their uses, and benefits.
03
Get hands-on knowledge of routers, switches, firewalls, and access points — the key devices that keep networks running smoothly and securely.
04
Understand how data flows across networks using the OSI Model and TCP/IP Model. These frameworks simplify complex communication processes and provide a universal language for IT professionals.
05
Learn how rules (protocols) like HTTP, FTP, DNS, and SMTP govern data transfer and why specific ports are used for services. This section builds confidence in analyzing and securing traffic.
06
Get introduced to firewalls, Intrusion Detection Systems (IDS), and Intrusion Prevention Systems (IPS) — the first line of defense against network attacks.
