Grokking Computer Networking for Software Engineers

The way applications are developed today requires software engineers to have a firm understanding of client-server architecture and networking.

If you’re planning to write web applications, or apps that communicate with a remote server, then networking is an essential skill. With this in mind, it’s clear that what you do as a software engineer will be deeply rooted in networking.

This course will teach you the fundamentals of networks, socket programming in Python, command-line tools and the main protocols of each layer.

Additionally, you will get hands-on experience with not only socket programming, but with implementing network protocols that require distributed processing.

Join us in a deep dive on everything network-related.
