Okay, imagine a radio tower, broadcasting the latest 40 pop songs to cars all over the city. If Internet allows you to access information from other computers across the world using a specific language (protocol), then WiFi is just a way of connecting to that wire in your living room wall and out to the Internet, wirelessly. Here is the differentiating factor between the I nternet and WiFi. The modem is used to translate the Internet signal from the outer world into a native language your computer can understand (don’t worry about this one) and the router is like a little tiny, itsy-bitsy radio tower that broadcasts WiFi throughout your home. One is called the modem and the other is called the router.
They’re the ones that make that physical connection to the web.įrom that Ethernet jack in the living room, you’re going to plug in two devices. Companies such as Comcast, Clearwire and CentruyLink are common ISP's. Your Internet service provider, or ISP, simply provides the cable that goes from your house to the Internet. It’s the "net" that ties them all together and it's also the language that computers use to speak amongst themselves. The Internet is what’s in between your computer, your server, your boss’s server and your boss’s computer. However, the server isn’t technically the Internet. So, when you type like you do everyday, you’re really just accessing another computer owned and operated by Facebook. Each server has a unique address on the Internet and that address is called its URL. A server is a computer thats sole purpose is to connect your computer to your boss’s computer.
Still with me? Let’s break that down a little. Your server then pushes your message to your boss’s server (also associated to his/her particular email address), which in turn pushes the email to their work computer. This computer is associated to your specific email and is called the server (remember that term). When you click "Send," that email is shot through the Internet tubes of society and lands on another computer somewhere on the Internet. Okay, you’ve typed out that shiny email to your boss and are about to send it off. Sounds about right, but how does it actually do that? When you send an email, you’re using the Internet to move that photo of your dog from one computer to another. Now here’s where it gets a little more complicated. The second aspect of the Internet is how that data actually moves from one place to another. Like speaking with someone in Chinese on the phone - the connection is there - but if you don’t understand the language, then there’s no way you’ll ever be able communicate. Without that protocol, even if two computers were connected with a cable, they wouldn’t be able to understand each other.
This language allows your computer to send and receive information to and from another computer.
The Internet is a way for one computer to talk to another - an internet lingo. Okay, now what’s the difference? The Internet is a Language If you can remember that moving forward, then half of my job is done. If I can get you to remember one thing, it’s this: WiFi and the I nternet are two completely separate beasts. There will be a few concepts introduced, but for the most part I teach in visual metaphors - so I’ll do my best to help you understand. I’ll do my best to put this into laymen's terms. Does that Jog your memory? Now the real question is this: do you know the difference between the I nternet and your WiFi network? If you don’t, stay calm and I’ll explain. Well, simply put, it’s a big huge network that’s changing humanity. I’m sure you’ve heard of the Internet… right? Duh.
