The Internet - along with all the applications it supports, such as the web - has become one of the most significant driving forces of technological progress in our time.

In this course, we will examine the key protocols that enable the operation of the internet, the web, and other applications in the field of computer networks. This will give you the opportunity not only to utilize modern networking technologies to their fullest potential but also to contribute to their development in the future.

About the Author: Oz Nova (CS Primer)

Oz Nova (CS Primer) thumbnail

Oz Nova is the founder of CS Primer (csprimer.com) and a co-founder of Bradfield School of Computer Science — an unusually rigorous CS-fundamentals education brand aimed at self-taught engineers filling in the formal computer-science foundations they didn't get from a four-year degree. The CS Primer course catalog goes deeper into the fundamentals than essentially any other paid online platform.

The course catalog covers compilers and language design, computer networks (from sockets through application protocols), distributed systems, computer architecture, operating systems, databases at the storage-engine level, and the algorithms / data-structures material taught at the level of a serious CS undergraduate course rather than an interview-prep cheat sheet.

The CourseFlix listing under this source carries 7 CS Primer courses spanning that range. Material is paid; CS Primer runs on per-course or membership pricing on the original platform. Courses are aimed at working software engineers ready to fill the foundational CS gaps that compound across a career.
