The basics of computer network explained simply and quickly

This training was created following over 15 years of experience, during which I observed:

• Network engineers that are skilled at configuring devices are not able to recognize even the most basic network issues because they do not understand how data flows, how network devices operate, or what their configuration actually performs.

• A PC technician who needs to set up static IP addresses and routes but is unaware of what a subnet mask is or what the default gateway is.

• System engineer who manages web servers but lacks knowledge of the distinction between private and public IP.

These are just a few examples of how a lack of networking knowledge causes a lot of network problems that waste hours. After completing this course, you will be able to quickly identify and diagnose any basic network issue, understand the layout and functioning of any computer network, and be familiar with the devices and protocols needed for basic communication.

Instead of teaching students how to configure networks, this course aims to teach them how networks actually function!

All network protocols and devices operate based on fundamental concepts that are covered in this course; therefore, understanding them is essential.

This course will cover network terminology, concepts, and topologies. You will also learn about the fundamentals of network devices, such as hubs, switches, routers, and firewalls, and how they operate. You will study key network functions such as ARP, NAT, and DHCP, comprehend what subnetting is and how it works, and ultimately discover how it all works together in a hop-to-hop simulation with packet structure.

This first course covers the fundamental concepts of networks with hop-by-hop in-depth examples and knowledge-testing quizzes, delving deeply into the bits and bytes of basic computer networking.
