Korshub's take

A Fast On-Ramp to Core Networking Concepts

This mini course moves briskly through the building blocks of computer networking, starting with the basic question "what is a network?" and working up to how a device actually joins Wi-Fi via the 4-way handshake. Along the way it covers networking hardware, addressing, and the protocols that quietly run in the background of every internet connection.

Who It's For

Aimed squarely at beginners with no prior networking background who want a solid conceptual foundation before tackling certifications or more advanced study.

What You'll Walk Away With

The difference between repeaters, hubs, and switches
How ARP resolves logical addresses to physical ones
Collision domains vs. broadcast domains
The OSI model explained through a real-world example
How DHCP, DNS, and the Wi-Fi handshake fit together

It's a condensed primer — students wanting deeper coverage can follow up with the instructor's full-length networking course.

About this course

What will you cover throughout the course?

We'll start from "What is a Network?" moving to "How the DNS works?" then to "How the Subnets and VLAN work?" and much more. We'll not stop there, after you're done analysing all this, later in the course, you'll learn how the 4-way Wi-Fi Handshake works.

Upon completion of this course, you will be able to understand the following:

What are Networks and their types?
The Networking Devices- Repeater, Hub & Switch
What is a Logical and Physical Network Address?
How the Address Resolution Protocol(ARP) works
Collision Domains and Broadcast Domains - what's the difference?
The OSI Model with a real-world example
The idea behind DHCP assigning you IP addresses
Working on the Domain Name System(DNS)
Wi-Fi and Access Points
Summary of the Wi-Fi 4-way handshake

and the list continues...

After finishing the course, you will be confident enough to explain and clarify all the networking stuff to yourself as well as to those who are in need of some solid and clear fundamentals.
