Refresh: The Internet
2 min read
Have you ever stopped to think about the Internet and how it works? I mean, it's a pretty amazing thing when you start to dive into it. So, let's explore the world of networking and the internet!
What is the Internet?
Well, it's a global network of computers that are connected to each other. This allows people all over the world to communicate and share information. But how does it all work?
Well, it all starts with networking. Networking is the practice of connecting two or more devices so they can communicate with each other usually done through a variety of methods, such as Ethernet cables, Wi-Fi, or cellular networks. Once devices are connected, they can communicate with each other through a set of rules called ✨protocols ✨. These protocols allow for the transfer of information between devices, such as web pages, emails, or files.
The foundation of data communication on the web is HTTP (Hypertext Transfer Protocol), which allows clients (like web browsers) to request resources (like web pages) from servers, and for servers to respond with those resources. HTTPS (HTTP Secure) is a secure version of HTTP that uses SSL (Secure Sockets Layer) or TLS (Transport Layer Security) to encrypt data during transmission. IPv4 and IPv6 are protocols that allow devices to communicate with each other over the internet. (Big words. Lots of abbreviations...I know)
So, what does all of this have to do with web development? Well, as web developers, it's important to understand how the internet and networking work so we can create websites that are fast 💨, reliable 👍, and secure 🔒.
Let's not forget DNS (Domain Name System), which is what translates human-readable domain names (like google.com) into IP addresses, which computers use to communicate with each other.
And of course, security is also a crucial aspect of networking for web developers. Understanding how to secure websites through protocols like HTTPS (HTTP Secure) and SSL (Secure Sockets Layer) can help protect user data and ensure a safe browsing experience.
So there you have it, a quick overview of the internet and networking. Remember, understanding these concepts can help you create better websites and ensure a smooth browsing experience for users.
