The invention of the internet is a landmark event in human history, revolutionising access to information. Never before has it been easier to access and share information across the globe.

Today, the internet is integral to our lives, benefiting virtually every industry—from grocery stores and banks to taxi services. Regardless of your future occupation, your career will benefit from understanding the underlying principles of computer networks.

This course explores the relatively simple principles that enabled the creation of one of the most complex systems ever developed: the internet. We will examine its components level by level, providing a comprehensive overview of how it functions.

Rather than training network engineers, this course aims to offer a broad perspective on the workings of the internet.
