Understanding Networking | Understanding Node.js Core Concepts

Node.js was designed to build network applications. In this video, we will learn about some important networking concepts and see where Node.js will come into play. We'll learn about Networking layers, TCP, UDP, IP and IP addresses, the Net, Dgram and DNS modules, and we will also build two very low-level applications, a chat app and also an uploader app built directly on top of TCP using the Net module. We will deploy these two apps into AWS as well to get a chance to learn more about Networking and Node.js in general.
