Imagine for a moment, how different your life would be without access to Facebook, Snapchat, Google, YouTube, Whatsapp, or any of the other websites on the Internet? How would you live with no Internet?

The Internet is extremely important in modern life today and all websites and Internet communication rely on networking. This reliance is only predicted to continue with the growth of the Internet of Things (IoT) in the next few years.

Without routers, switches, network cabling, and protocols like BGP there would be no Internet!

The 20th Century has all been about information gathering, processing, and distribution. In the past few decades, the world has seen tremendous growth in these fields, from telephone networks to radio and television, from highly centralized huge computers to the smart-phones and smart-watches of today. The internet has been instrumental in connecting this world together, to billions of people and millions of devices. And this trend will keep growing rapidly throughout the 21st century too!

With thousands of businesses and millions of devices using networking for operations, Computing Networking is one of the most essential fields for study for any IT aspirant. The internet revolution has made it virtually the most essential domain knowledge to possess for everyone today.
