Networking Basics: LANs, WANs, and Security
A comprehensive introduction to the fundamental concepts of computer networking, covering LANs, WANs, IP addressing, routers, switches, subnets, NAT, and firewalls. Learn with interactive simulations, quizzes, and real-world examples.
Program Modules
Introduction to Networking Concepts
Overview of networking principles and key components. We'll start with the basics and build a strong foundation for more advanced topics.
Understand Network Types (LAN & WAN)
WeeklyLearn about Local Area Networks (LANs) and Wide Area Networks (WANs). Explore real-world examples of each.
“The first variety of networks is a local area network also known as Lang. A wide area network or a van is in its most basic form a collection of local area networks for any other networks that interact with one another. - SimplyLearn”
IP Addressing Basics
WeeklyGrasp the importance and structure of IP addresses in a network environment. Understand how IP addresses are assigned and managed.
“An IP address is a lengthy string of digits allocated to any device connected to a network that utilizes Internet Protocol as the communication medium. - SimplyLearn”
Core Networking Devices
Understanding the functionality of switches and routers. Learn how these devices work together to create a network.
Switches: Connecting Devices
WeeklyExplore the role of switches in connecting devices within a network. Understand MAC addresses and how switches use them.
“A network switch joints devices in a network such as computers printers wireless access funds and allows them to communicate with each other by exchanging data packets - SimplyLearn”
Routers: Inter-Network Communication
WeeklyLearn how routers enable communication between different networks. Explore routing tables and how routers find the best path for data.
“A rocker is employed at the Forefront of every network setup to facilitate communication between foreign Networks this router can then be used to connect to the Internet so we can communicate with the loved ones from the comfort of our own homes. - SimplyLearn”
Advanced Networking Concepts
Understanding subnetting, NAT, and firewalls for network security. Learn how to protect your network from threats.
Subnets and Network Address Translation (NAT)
WeeklyExplore the concept of subnets and the functionality of NAT. Learn how subnets improve network management and security.
“All these IP addresses must belong to a particular range of addresses which are often known as the subnet or sub Network and which help determine the overall range of a local area network. - SimplyLearn”
Firewalls, DMZs, and Port Forwarding
WeeklyLearn about firewalls, demilitarized zones (DMZs), and port forwarding. Understand how these technologies protect your network.
“A firewall is a type of network security device that analyzes the incoming and outgoing networking traffic and allows organized data packets depending on a set of security rules its objective is to provide a barrier between your local network and external jackets such as the internet. - SimplyLearn”
